Walking inside the building of the school, Judai is thinking about what Asuka said before about Sho. In fact, Sho has a brother studying in this school. His brother is the top duelist among third-grade students and is named Kaiser. In the school store, Judai is sitting and keeping on thinking about something happenning between Sho and his brother. Because Judai doesn't know anything, he would like to duel against Sho's brother to figure out the truth. Then Professor Chronos just comes in, seeing Judai writing something. He walks behind Judai, takes out the paper that Judai is writing, and reads it. Judai wrote his desire opponent on the paper. Professor Chronos is amazed when he sees the name of Kaiser. Judai asks for his paper back because he hasn't finished writing yet. Professor Chronos looks down Judai and tells him that it is 1,000,000 years too fast for drop-out Judai to duel against the number of the Duel Academy, Marufuji Ryo. After that, Professor Chronos tears out the paper while Judai is getting shocked.

At the Osiris Red dorm, Sho has been keeping himself quite in his bed, looking at his sealed magic card Power Bond. He feels very painful when he thinks of his brother's words. Ryo told him that this card would be sealed until Sho was worth to use it. Now, Sho thinks that he is not worth even to become Judai's partner. He imagaines and dreams of what is going to happen in the coming tag duel that he and Judai have to become partners. His opponent may control Sho's monster to attack Judai until Judai is defeated. Sho is very afraid if he will hurt his big brother. Turning his face toward his opponent, Sho sees an appearance of his brother, Ryo, laughing. Suddenly, Sho gets up from his nightmare with shock.

In the wood, Hayato is making up his deck alone on a tree. He has his last card [Death Koala] on his hand that may not match and compete. Then Judai is walking over there, getting mad by Professor Chronos' previous behavior. Hayato accidently drops his cards onto Judai's head. He almost falls down from the tree but he can catches a brance in time. Judai turns up and sees Hayato, who is hanging himself on the tree, looking like a Koala. He picks up a dropped card and guesses that Hayato is trying a duel. However, Hayato tries to say that it is merely a card fortune-telling. Of course, Judai seemingly doesn't believe him at all. Then Judai has just realized that he is in a hurry, starting to turn back and continue running. Hayato asks where Judai is heading for. Judai tells him that he is going to Obelisk Blue to duel against Kaiser. Certainly, Hayato is very shocked , he then falls down from the tree.

Certainly, Judai is kicked out from Obelisk Blue by students. They think that it is very ridiculous that a drop-out boy from Osiris Red dare challenge Kaiser for a duel. Also, they throw water over Judai and laugh to chase him out. Judai is getting angry while Hayato hiding and looking behind has expected that this should exactly happen. In the evening, Hayato and Judai are walking together back to their room. Hayato tells Judai to give up. Nevertheless, Judai is still stubborn. No matter what, he intends to duel against Kaiser. When both of them enter their room, Judai sees Sho probably sleeping on the bed. Judai thinks that Sho is acting like Hayato (sleeping on the bed all the time). Thus, Hayato gets mad and tells Judai to shut up. However, when Judai opens the sheet, he doesn't see any appearance of Sho. Hayato just sees a note from Sho on the table. Judai takes it and reads at once.

A note from Sho Sho is going to leave the island. Don't try to stop me, Big Brother. Just good-bye to this life.

Judai is getting mad by that Sho intends to run away. Hayato asks what they should do next. Judai tells him to look for Sho immediately. Anyway, Hayato is uncertain because the dinner has almost been ready. Therefore, Judai has to drag him out to search for Sho around the island. They try to call Sho to let him show up and move around edges along the island. Hayato feels pity that the dinner may have already been over. At the same time, Sho is preparing for leaving the island by a raft. As Judai is still looking for Sho, his deck starts shining, and Hane Kuriboh comes out and hangs on his shoudler. Hayato feels that he hears the familiar voice of "Kuri Kuri" again. Hane Kuriboh guides Judai to follow it. Judai understands that Hane Kuriboh is trying to tell him where Sho is, so he goes after it at once.

Under a lighthouse on a pier, Asuka walks to see Ryo standing and looking into the sea. Ryo asks whether Asuka got anything about her brother. Asuka is afraid to say that she got nothing. Everything has passed normally through the wave without any trace. Anyway, Ryo tells her not to be hurried. She must be able to do it someday. Then Asuka changes the topic. She tells Ryo about Sho's duel. Because of that, Judai is now looking for Ryo for a duel. Ryo has just remembered that Judai was a new candidate in the entrance exam. While they are still talking, they hear some voice of Sho from the other side. At this moment, Sho is getting scared when he sees Judai chasing after him. Thus, he jumps on his raft and trying to escape. Seeing that, Judai jumps over on the raft. Suddenly, the raft is broken and both of them fall into the water. Sho is screaming and asks for help because he can't swim. He tries to hold himself with Judai until both of them sink into the water. Hayato hurries to jump after to save them, yet he finds that the water floor is very shallow. Then Judai and Sho appear from the water safely. Sho tries to tell Judai not to be worried about him and finds a new partner. However, Judai has already decided that his partner must be only Sho. Sho still refuses because now he can not win at all.

Ryo	Did you catch up something?
Asuka	Um...there is nothing changed in the whole day. Everything has passed with nothing. My brother's trace has gone through the wave.
Ryo	Don't be hasty. You will...some day.
Asuka	I got it. Anyway, did you see your younger brother's duel...?
Ryo	Then why...?
Asuka	I don't want to say but about this...Yuki Judai has been looking for you for a duel.
Ryo	Yuki Judai. Ah! that new candidate in the exam.
Asuka	Why don't you try...Ryo?

Then Sho and Asuka appear over there. Sho is shocked to see his brother. Judai has just first seen Kaiser by his own sight. Ryo asks whether Sho intends to run away. Anyway, Sho hesitates to answer. Thus, his brother says that it may be good for him. Feeling upset, Sho turns back and cries. Judai is unpleased with Ryo's act to his younger brother. Ryo says that he can't help anything. Judai argues that at least Ryo should have given farewell to the younger brother. Therefore, Judai challenges Ryo for a duel and Ryo accepts it. As Sho feels uncertain about Judai's decision, Judai tells Sho to merely watch his duel carefully.

At the seaport in front of warehouses, the duel between Judai and Ryo has finally begun. Sho is getting worried because he causes this duel. Anyway, Judai still enjoys the duel as usual. First turn comes to him. Drawing a card, Judai summons [E-Hero Featherman 3/1000/1000] in an attack mode. He sets up a reversed card and ends his turn.

Cyber Dragon Monster Card

Come to Ryo's turn. He draws a card and summons [Cyber Dragon 5/2100] in an attack mode. Judai is getting surprised when he sees Ryo summoning the strong monster without sacrification. Thus, Ryo explains the special ability of Cyber Dragon. While the opponent has some monster on the field while the player doesn't, Cyber Dragon can be summoned without sacrification. Getting worried a bit, Judai tries to accept this great play. After that, Ryo plays a magic card [Mystical Space Typhoon ~ Cyclone] that can destroy one magic or trap card on the field. Of course, Ryo uses it destroy Judai's reversed card. Then he declares the attack of Cyber Dragon, Evolution Burst, against E-Hero Featherman. Therefore, Judai's LP goes down to 2900 (4000+1000-2100). After that, Ryo plays another magic card [Different Dimension Capsule]. By its effect, Ryo has to select a card from his deck and remove it from the game by putting it into Different Dimension Capsule. The selected card will be activated in the next two turns. Having placed into the Different Dimension Capsule, Ryo's chosen card is disappeared with it from the field. Although Judai doesn't understand what kind of the favourite card Ryo selected from his deck, he feels very excited. Anyway, only Sho can guess what that card may be (Power Bond). Then Ryo ends his time.

Judai thinks that Kaiser (Ryo) is really great as what people said. Merely in the first turn, Ryo could set up all tactics for every movement. Entering his time, Judai draws a card and plays [Polymerization-Yuukou] to fuse [E-Hero Sparkman 4/1600/1400] with [E-Hero Clayman 4/800/2000] to [E-Hero Thunder Giant 6/2400]. He activates the special effect of E-Hero Thunder Giant at once. When it is summoned, it can destroy a monster with lower base attack points on the opponent's side of the field. As a result, Cyber Drago is destroyed by this effect. When Ryo has no monster left, Judai declares the attack of E-Hero Thunder Giant against Ryo directly. Getting hit strongly, Ryo's LP decreases to 1600 (4000-2400). Setting a reversed card, Judai ends his time. Sho thinks that his Big Brother (Judai) is also great. Anyway, he believes that his brother hasn't shown up his real strength yet.

Cyber Twin Dragon Monster Card

Turn comes to Ryo. He draws a card and gets Cyber Dragon. Therefore, he activates its special ability to summon it onto the field without sacrification again. After that, he plays a magic card [Monster Reborn-Shisha Sousei] to regenerate another Cyber Dragon from his cemetery. When there are two Cyber Dragon on the fields, Ryo uses [Polymerization-Yuukou] to fuse them to [Cyber Twin Dragon 8/2800]. By its special effect, Cyber Twin Dragon can do twice attacks in a battle phase. While Hayato is getting amazed, Asuka explains that Judai will get the direct hit in the second attack. Sho has realized that this is his brother's dueling style. In order to win... no one can beat it even Big Brother (Judai). Then Ryo declares the attack of Cyber Twin Dragon, Evolution Twin Burst, against E-Hero Thunder Giant. At this moment, Judai opens his reversed trap card [A Hero Emerges - Hero Kensan]. When Ryo declares an attack, Ryo can select a card randomly on Judai's hand. If the selected monster is a monster card, Judai can summon it specially onto the field. There is only one card left on Judai's hand and it is a monster card [Friendog 3/800/1200], so Judai can automatically summon it onto the field in a defense mode. However, both E-Hero Thunder Giant and Friendog are all destroyed by the twice attacks of Cyber Twin Dragon. Thus, Judai's LP goes down to 2500 (2900+2400-2800). When Friendog is sent into graveyard, Judai can activates its special effect. It allows Judai to get back a [Polymerization-Yuukou] card and a monster with [Elemental Hero] in its name into his hand. Thus, Judai gets Polymerization and E-Hero Clayman back. Then, Ryo ends his time. At this moment, Judai tells Ryo that he gets excited and enjoys this duel a lot. It is surprised that Ryo replies Judai that he also feels the same. Sho is very amazed by his brother's response to Judai.

E-Hero Mudballman Monster Card

Come to Judai's turn. Drawing a card, he gets [E-Hero Bubbleman 4/800/1200] and summons it into an attack mode. When this card is successfully summoned, Judai can draw additional two cards from your deck. This time, he gets his partner [Hane Kuriboh 1/300/200] and [Wing of Evolution - Shinkasuru Tsubasa]. Of course, he plans to use Wing of Evolution so that Hane Kuriboh can evolve itself as he did this play before against Manjyome. When Hane Kuriboh evolve to Hane Kuriboh Level 10, it can be sacrificed to destroy all of the opponent's monsters. Then the total attack points of the destroyed monsters will deal directly to the opponent. In other words, the total attack points of Cyber Twin Dragon (2800) will deal directly to Ryo (2600) and Judai will finally become the winner. However, Judai can't summon Hane Kuriboh in this turn because he has already summoned normally E-Hero Bubbleman. Thus, he has to wait until next turn to summon Hane Kuriboh normally. In order to handle Ryo's next attack, Judai plays Polymerization again to fuse E-Hero Clayman on his hand with E-Hero Bubbleman on the field to summon [E-Hero Mudballman] with 3000 defense points specially in a defense mode. Hayato is glad to see Judai's great play. He thinks that the twice attacks of Cyber Twin Dragon (2800 points for each hit) will be invalid against 3000 defense points. However, Sho understands that the key card of his brother will be unsealed in the next turn. Then Judai ends his time.

Ryo	Judai, this should be our final turn.
Judai	Ah, I am getting excited by what is gonna happen.
Ryo	I see that. You have played by your best. In return, I will bring out all of my power. I give repect to your duel.
Sho	(My brother is approving the duel of Big Brother, isn't he?)
Judai	(Kaiser, that sounds like you are going to tell Sho those words.)

Cyber End Dragon Monster Card

Ryo continues his turn. Playing a magic card [De-Fusion] to separeate Cyber Twin Dragon into two Cyber Dragons, he plays [Power Bond] from his hand. Of course, Power Bond was the card previously sealed in Different Dimension Capsule. Ryo explains that this card is treated as a Fusion magic card. It only works for machine monsters. He fuses two Cyber Dragons on the field with another Cyber Dragon on his hand to summon [Cyber End Dragon 10/4000/2800]. By another special effect of Power Bond, the summoned fusion monster can double its attack points. In other words, Cyber End Dragon's attack points go up to 8000 (4000*2). In addition, Ryo describes the special effect of Cyber End Dragon. When it attacks a defending monster with lower defense points than its attack points, it can deal damage equal to the difference directly to the opponent. Hayato tries to cheer Judai up to withstand this attack. By another effect of Power Bond, it forces Ryo to deal damage equal to the original attack points of the attacking monster to his own LP at his end phase of the turn that he activated Power Bond. To explain, if Judai can stand 8000 attack points of Cyber End Dragon, Ryo has to deal 3000 original attack points of Cyber End Dragon to himself (2600) at the end of this turn following the effect of Power Bond. Then Judai will win. Asuka thinks that the player usually has to take some risk to play Power Bond. However, only Sho understands how his brother is feeling. The risk isn't the problem for his brother, but respect toward the opponent significantly matters. From this point, Judai has already prepared for his coming destiny with fighting spirit of a duelist. Ryo declares the attack of Cyber End Dragon, Eternal Evolution Burst, against E-Hero Mudballman. As a result, Judai's LP goes down to 0 (2500+3000-8000).

People are all surprised by that Judai was finally defeated. Sho feels sorry to his Big Brother (Judai), running toward him. Although Judai was defeated, he tries to keep himself up and says his favourite words that he enjoyed the duel very much; what a nice duel! Seeing Judai's response, Ryo smiles a bit. He looks at Sho who has already changed his attitude and grown up. While Ryo is walking back, Asuka follows him and asks about the duel. Ryo thinks that Sho has such a nice brother. Judai also shares the same feeling. He thinks that Sho's brother is such a great man. He also tells Sho to go back, and he will help Sho recreate his deck. Nevertheless, this time, Sho agrees to unseal his Power Bond and use it. By the way, Hayato tells his friends that the dinner has already been sealed. Then people have just realized that they are all hungry. Thus, Judai tells Sho and Hayato to return to their dorm at once. Perhaps, they may be there in time...

Hayato	Judai
Asuka	Yuki Judai was...defeated?
Sho	Big Brother....Big Brother!
Judai	What...a nice duel~
Asuka	How was it?
Ryo	Sho has such a good brother, hasn't he!
Judai	What a great brother!
Sho	Hum...my big brother (Judai) too!
Judai	Well, let's go back and work on the deck.
Sho	Um!
Judai	But this time, we have to think about how to use Power Bond, Sho!
Sho	I got it. I am going to release the seal of it.
Hayato	But the meal at the dorm has already been sealed.
Judai	Perhaps, we can still go back in time.
