At night at Duel Academy, there is a mysterious and giant student dueling against an Obelisk Blue student. This is an anti-rule duel; the loser must give the winner his rarest card. Having defeated, the Obelisk Blue student loses his rare card. The giant guy turns back into the night as there is another Ra Yellow guy watching after him and smiling.

At Duel Acedemy, Obelisk Blue students are talking about the current rumor of the anti-rule duel and a mysterious giant guy. Judai, Sho, and Hayato come across and ask what is going on. However, the Obelisk Blue students leave them quickly and say nothing. Hayato says that this should be related to the rumor spreading throughout the school; Obelisk Blue students are challenged and defeated by the mysterious giant duelist, so they have to lose their rare cards. Hayato calls him Giant Duelist of Dark Night [Yami No kyojin Duelist].

Meanwhile, Professor Chronos is getting worried by the current situation since his Obelisk Blue students are knocked off by the unknown duelist. Furthermore, the anti-rule duel is the violation of the school rules. Seeing Judai and the others on his way, Professor Chronos comes up with an idea. He offers them some good condition. If they can do this special assignment very well, they will be exempted from the duel theory writing report. Judai looks very happy as Sho seems not to trust Professor Chronos. Judai is curious what kind of that assignment is gonna be. Professor Chronos tells them that they have to find the mysterious duelist and disclose his real appearance. Judai realizes that Professor means the giant duelist coming at night following the rumor. Professor leaves this work on them before he leaves. He thinks that those drop-out boys should try their best by this incentive. If Judai loses, Professor is gonna be happy anyway since Judai has to lose his rare card. Sho and Hayato look uncertain about this assignment because Professor Chronos doesn't look reliable. Judai asks what people are talking about; if they can do this job successfully, they don't have to send the report. Also, Judai isn't worried at all but becomes enthusiastic to duel against the great duelist as usual. In fact, Sho and Hayato realize that they can't stop this habbit of Judai anyway. Sho asks what Judai plans to find that mysterious giant guy. Judai tells them to leave his work on himself.

Chronos	Those drop-out boys!
Sho	Ah! Professor Chronos!
Chronos	I have some special assignment for you.
Judai	Special assignment?
Chronos	If you can do this job very well, I will exempt your duel theory report.
Judai	Really!?
Sho	Heee...how bad, Big Brother.
Chronos	That is true. Look into my eyes.
Judai	Of course, I will do it.
Hayato	Judai!
Judai	Well, what is that assignment?
Chronos	Now, someone is challenging other students for a duel by the anti-rule, right? You just catch him and disclose his real appearance.
Judai	You mean that giant duelist of dark night?
Chronos	Ahh...you are going to do it certainly anyway. (hi hi hi, by this point, they will do well on looking for the mysterious duelist. I still feel happy anyway if he is defeated and loses his rare card.)

Inside the duel arena, a Obelisk Blue student is dueling against a Ra Yellow student [Kohara]. The Obelisk Blue student with 200 LP has a monster Troop Commander in an attack position and a reversed card on his field [Troop Commander ~ Kirigomi Taichoo - 3/1200/400: While your opponent does not destroy this Monster, your other Warrior Sub-Type monsters cannot be attacked. When you successfully Summon this card, you may Special Summon 1 Monster with a Level of 4 or less from your hand]. On the other hand, Kohara with 300 LP has Mad Sword Beast in an attack position on his field [Mad Sword Beast ~ MosinSuru Kengakuju - 4/1400/1200: When this Monster attacks a Monster in defense mode with a lower defense strength, do damage to the defending player equal to the difference]. Judai, Sho, and Hayato have just arrived the audience seats, seeing the duel on process. The Obelisk Blue student tries to urge Kohara to go on his turn as Kohara looks confused. He looks at his cards on hand and has no idea what he should play next. Judai sneaks to Kohara's cards, seeing the magic card Earthquake [Earthquake - Magic: Switch all face-up Monsters on the Field into defense mode]. Therefore, he is sure that Kohara's victory has already been decided by that card. Anyway, Kohara is still worried about the reversed card. Although his monster now has higher attack points than his opponent's, he is uncertain whether he should activate Earthquake to change the position of Troop Commander into a defense position. Meanwhile, many Obelisk Blue students try to urge Kohara to play. No matter how much Kohara tries, they know that he can't win anyway. His opponent shouts at Kohara, challenging him to declare the attack quickly. Kohara doesn't have any idea what he should do, so he decides to declare the attack of Mad Sword Beast against Troop Commander without activating anything. Judai is getting surprised by Kohara's decision. Suddenly, the Obelisk Blue student opens his trap card Reinforcements [Reinforcements ~ Engun - Trap: Increase the attack strength of 1 Monster by 500] that can increase the attack points of Troop Commander by 500 points. As a result, the attack points of Troop Commander become 1700 (1200+500), so Mad Sword Beast with 1400 attack points is destroyed. Kohara's LP goes down to 0 (300+1400-1400), and he is finally defeated.

Judai feels pity to Kohara since Kohara should have won this game if he had activated Earthquake. Then, Misawa appears. He tells people that Kohara is, in fact, pretty strong. However, people usually intimidate him until he is defeated. Most Obelisk Blue students laught at Kohara, telling to quit dueling. Kohara says nothing but walks out quietly and clamly. Then, his face looks different and turns into a serious face. Seeing Kohara's act, Judai can feeling something weird. Even Hane Kuriboh appears near Judai to confirm his feeling. By the way, Misawa asks whether everbody comes here to inspect and learn about this duel. Sho tells Misawa that everyone is, in fact, looking for the criminal, the giant duelist of dark night. Misawa has heard about this rumor before. Kohara is walking to see a giant guy in an exit. Sho is wondering, asking Judai whether that giant may be the criminal whom they are looking for. Misawa disagrees that Ohara shouldn't be the criminal since he aims to become a game disigner not a duelist. However, Sho is still suspecting, so is Judai. He decides to go after Ohara and Kohara while Hayato and Sho follow him.

Ohara and Kohara are walking along the way in the building. Then, the group of Obelisk Blue students walk pass, ordering them to open their way. Kohara doesn't want to have any trouble, so he and Ohara complies to Obelisk Blue students easily. Of course, Kohara is getting furious but he can't do anything. Suddenly, Judai and the others reach him. Judai asks Ohara whether he is actually the mysterious duelist. While Ohara looks frightened, Kohara asks what Judai means by that. Of course, Judai challenges him a duel if Ohara really defeated those Obelisk Blue students. Kohara doesn't understand what Judai is talking about, telling him to stop his words. Then, he takes Ohara back. Hayato reminds Judai of Misawa's words that Ohara wasn't the criminal. Sho agrees with Hayato. He doesn't feel that Ohara is the giant duelist of dark night. Nevertheless, only Judai and Hane Kurioh now feel different from the others.

At night at Ra Yellow dorm, Kohara is arranging his deck with Ohara. He feels that he can't forgive the Obelisk Blue student whom he dueled against today. At the same time, Sho, Hayato, and Judai are waiting for the mysterious duelist to appear in front of the school. Hayato starts feeling that he probably should have selected to write the report rather than catching the criminal. Suddenly, people hear the scream from the forest. Judai first runs in the front. Going into the forest, he sees the Obelisk Blue student whose rare card was already taken. Judai asks where the criminal went and follows his way quickly. Hayato and Sho who follows him realize that this Obelisk Blue student is the same person who dueled against Ohara in the afternoon. Then, all people see a giant guy wrapped around by many Obelisk Blue coats; undoubtly, he must be the criminal or the mysterious giant duelist. Sho tells Judai to run away since the giant guy looks scary. Of course, Judai gets more excited as usual, challenging the giant duelist of dark night for the duel.

Judai understands that the giant duelist of dark night duels by the anti-rule. Seeing Hane Kuriboh appears, Judai trusts it and decides to let it fight with him in this game. Judai declares that if he is defeated, he will give Hane Kuriboh card. He shows up the card, claiming that this rare card was given by the duel king, Mutou Yugi. Sho is surprised by that Judai is betting by his important and valuable card. Hayato sees Judai become very serious, so he understands that nobody can stop him now. The giant duelist of dark night accepts Judai's offer following the guiding voice, hoping that Judai won't regret later. Standing by their duel disks, the duel between the giant duelist of dark night and Judai begins.

Giant Orc Monster Card

First turn comes to the giant duelist of dark night. Drawing a card, he summons Giant Orc in an attack position [Giant Orc - 4/2200/0: When this card attacks, it changes to defense mode at the end of the Battle Phase. Until the end of your next turn, this card's mode can't be changed]. Sho is amazed by the great monster with 2200 attack points summoned in the first turn. Hayato has just realized why that guy could beat many Obelisk Blue students. However, Judai points out the weakness of this monster. When it attacks, it must turn into a defense position with 0 defense point. Thus, it doesn't seem scary as it looks. Then, the giant duelist of dark night ends his turn.

It is now Judai's turn. He draws and gets Hane Kuriboh. Judai intends not to give it to anyone, so he hopes it will help him again in this game. As a result, he decides to summon Winged Kuriboh [Winged Kuriboh ~ Hane Kuriboh – 1/300/200: When this Monster is destroyed in Battle, all Battle Damage is reduced to 0 for this turn] in a defense position and ends his turn.

Second Goblin Monster Card

Next, the giant duelist of dark night draws a card and declares the attack of Giant Orc against Hane Kuriboh at once. Judai thanks Hane Kuriboh for its sacrification. At this point, Giant Orc must turn into the defense position according to its special effect. Sho claims that this is such a good time to beat Giant Orc. Anyway, the giant duelist of dark night summons the monster Second Goblin in the attack mode [Second Goblin - 1/100/100: Once per turn during your Main Phase, you may change this card to an Equipment card, and Equip it on 1 of your Giant Orc, or remove it from being an Equipment card, and place it in face-up attack mode. While this card is an Equipment card, the Equipped Monster's mode can be changed once]. Sho is getting amazed by the monster with the equipment ability. When this card is eqiupped with Giant Orc, Giant Orc can change its position in a turn. In other words, in this turn, Giant Orc eqiupped with Second Goblin can turn back to the attack position again. As Sho is getting pity, Hayata is impressed by the smart combo. After that, the giant duelist of dark night ends his turn.

Come back to Judai's turn. He draws a card and plays Polymerization [Polymerization ~ Yuukou – Magic: Fuses 2 or more Fusion-Material Monsters to form a new Fusion Monster] to fuse E-Hero Burst Lady [E-Hero Burst Lady - 3/1200/800] and E-Hero Clayman [E-Hero Clayman 4/800/2000] into E-Hero Rampart Gunner in a defense position [E-Hero Rampart Gunner - 6/2000/2500: This card can only be special summoned by fusion summon. If this Monster is in defense mode, you can attack your opponent directly. Battle Damage done by this effect is halved]. Judai then activates its special effect when it is in the defense mode. It can deal damage by a half of its attack points to the opponent. As a result, E-Hero Rampart Gunner shoots at the giant duelist of dark night until his LP decreases to 3000 (4000-2000/2).

Suddenly, all Obelisk Blue coats are scatter, and Ra Yellow Ohara shows up. Everybody is getting amazed by the true appearance of criminal as Ohara. Anyway, Judai calls out the real duelist of dark night to duel by himself. Hayato and Sho still get confused by the situation. Suddenly, Kohara appears from behind rock. He is the one who has controlled Ohara to duel. Kohara is wondering how Judai can figure out this truth. Judai explains that Ohara seemed not to play by his real strength. He looks like a doll played by someone. Thus, Kohara has to accept the truth that he has been behind the duels of Ohara. From the duel of Kohara in the afternoon, Judai has realized that Kohara had such strong cards. However, Sho still doesn't understand why Kohara has to do this. Kohara doesn't understand himself either. Whenever he is under pressure, he is usually defeated. Similarly, although Ohara is a big guy, he is usually teased. Kohara claims that the real bad guys are supposed to be those Obelisk Blue students. As a result, Kohara and Ohara join together to beat them up. Sho has just realized why Kohara duels by the anti rule. Anyway, Judai asks whether there is some meaning of these acts. He says that losing a game may be mortifying. However, people have fun in a duel when they put their hard effort.

King Goblin Monster Card

Kohara tries to tell Judai to shut up. No matter how much Judai claims, Kohara will win this game. Then, the game is continued. Ohara plays under Kohara's guide. When Ohara draws a card, Kohara tells him to summon King Goblin in an attack position [King Goblin - 1/0/0: If there is a Demon Sub-Type Monster on your Field other than this card, this card can't be attacked. This card's attack and defense strengths are equal to 1000 times the number of Demon Sub-Type Monsters on the Field, other than this one]. Judai is getting amazed by 0 attack point monster despite its attack mode. Discarding two warrior-type monsters into the graveyard, Warrior Dei [Warrior Dei Grepher ~ Senshi Dai Grepher - 4/17001/600] and Big Shield Gardna [Big Shield Gardna - 4/1000/2600: Negate the activation of a Magic card that targets this 1 card while face-down. At that time, this card changes to face-up defense mode. At the end of the Damage Step in which this card received an attack, it changes to attack mode], Kohara can summon specially two Half Goblins in a defense position [Half Goblin ~ Gobu Goblin - 3/500/500: Discard 1 Warrior Sub-Type Monster from your hand in order to Special Summon this Monster from your hand]. Then, Kohara activates the special of King Goblin. Its attack and defense points can increase by 1000 multiplied by the number of other Feind-type monsters on the field. As a result, King Goblin consumes the attack points from the three Feind monsters on the field, Giant Orc and two Half Goblins, and its total attack points become 3000 (1000*3). Kohara declares the attack of King Goblin against E-Hero Rampart Gunner in the defense position. Then, he lets Giant Orc attack Judai directly, so Judai's LP goes down to 1800 (4000-2200). Due to Giant Orc special effect, it has to turn to the defense position after attacking. Nevertheless, according to the equipment monster, Second Goblin, Giant Orc can turn its position back to the attack position. Then, Kohara ends his turn.

Kohara asks whether Judai has already seen his real strength. Judai disagrees and tells him that Kohara merely uses another person to become strong. Thus, he can't be the true duelist at all. It's now Judai's move. Drawing a card, he plays Pot of Greed [Pot of Greed ~ Kou Yuku Na Tsubo - Magic: Draw two cards from your deck] to draw additional two cards. After that, he summons E-Hero Sparkman [E-Hero Sparkman - 4/1600/1400] in the attack position. Also, he equips Spark Gun [Spark Gun - Magic: This card can only be equipped to an E-Hero Sparkman. You can change the mode of 1 Monster on the Field. This effect can be used more than once, but if used 3 times, destroy this card] with E-Hero Sparkman. According to the effect of Spark Gun, Judai lets it change the mode of monsters by three times; change two Half Goblin into the attack mode with 500 attack points each and change Giant Orc to the defense mode with 0 attack point. After this effect is activated by three times, Spark Gun is destroyed. Then, Judai plays The Warrior Returning Alive [The Warrior Returning Alive ~ Senshi No Seikan: Place 1 Warrior Monster from your Cemetery into your hand] to return a warrior-type monster, E-Hero Clayman, from his graveyard onto his hand. He fuses E-Hero Clayman on his hand and E-Hero Sparkman on his field into E-Hero Thunder Giant [E-Hero Thunder Giant - 6/2400/1500: When this Monster is Summoned, destroy 1 Monster on your opponents Field face-up with attack strength base lower than attack strength of this Monster] in an attack position. Once summoned, E-Hero Thunder Giant can destroy a monster with lower attack points on the field. Therefore, Giant Orc with its eqiupment monster, Second Goblin, is first destroyed by this special effect. Next, Judai declares the attack of E-Hero Thunder Giant (2400) against Half Goblin (500). Thus, Kohara's LP goes down to 1100 (3000+500-2400).

Anyway, Kohara claims that he still has some LP left. Judai doesn't think so, claiming that this should be the final turn. He plays De-Fusion [De-Fusion ~ Yuukou Kaijyo: Return 1 Fusion Monster Card on the Field to its' owner's Fusion Deck. If all the Fusion-Material Monsters for the returned Fusion Monster Card are in the Graveyard, they can be Special Summoned to the Field at this time] to separate E-Hero Thunder Gaint into H-Hero Sparkman and E-Hero Clayman normally. Judai declares the attack of E-Hero Clayman (800) against Halk Goblin (500), so Kohara's LP decreases to 800 (1100+500-800). Lastly, Judai lets E-Hero Sparkman destroy King Goblin, which has 0 attack point since there is no other Feind monster left on the field. Therefore, Kohara's LP becomes 0 (800-1600).

Kohara accepts his defeat, telling Judai to do as he wants. Anyway, Ohara asks Judai for the forgiveness of Kohara. He always appreciates for what Kohara has felt and done for him for a long time. As a result, Ohara would like to pay him back by receiving the punishment alone. He also believes that Kohara must become a strong duelist. Kohara knows exactly that Ohara would like to become a game designer. Ohara, in fact, doesn't care what will happen to him. He just wants Kohara to be safe. Judai tells Kohara that he has such a good friend. Although an individual strength is neccessary for a duelist, friendship is also important. Then, Judai decides to let them go, saying that he really enjoys the duel as usual. Kohara tells Judai that he must be a strong duelist in a day, and hopes that Judai will wait until that time has come.

When Kohara and Ohara leave, Sho reminds Judai of the duel theory writing report following the condition of Professor Chronos. Leaving the criminals go means that everybody has to write the report. Judai is getting shocked since he has just remembered it. Next day at Duel Academy, people report Professor Chronos that there is no mysterious duelist; meanwhile, Judai and Sho are writing a ton of theory report. Looking for the criminal, Judai didn't find him anywhere. Certainly, Professor Chronos doesn't believe this story. He asks how Judai will explain about that Obelisk Blue students' rare cards were taken. Judai tells Professor Chronos that those students are holding their rare cards normally, so Professor Chronos is getting surprised by what he means. Outside the school, Obelisk Blue students are glad to see that they have got their rare cards back. Kohara and Ohara, looking behind, decide to return those cards to them. Although this case can be closed happily, Judai still has to finish a ton of his writing reports.
