A gnashing game and an invited model

At the airport, the top model named Ailean Rao has visited Japan for her personal business. Many reporters try to interview her the important reason why she's come to Japan and left her Paris fasion show. Anyway, Ailean gets on her friend's car and leaves the airport quickly wihout answering any question. A reporter remembers that the driver in the car is the top soccer player named Heda. Ailean asks Heda take her to a place while Heda tries to invite her for a date. She refuses his invitation because she comes to Japan to play a game against a person. Then Heda says that he can be her opponent if she wishes. He can play any kind of game, pocker even chess. As a result, Heda takes Ailean to his condomenium to play a game. Ailean challenges Heda to play a game called, Rijinhai. It is similar to chess game. If Heda wins, Ailean must follow his direction while if Ailean wins, Heda will lose his important thing. Then the game begin...

At Kaiba's mansion. Ailean is coming into Kaiba's room. Kaiba asks why she's come late. She says that she had to play a boring game against a stupid guy. Then she asks Kaiba for her new target. Kaiba opens TV and lets Ailean see the news. A reporter is reporting that Heda, the top world soccer player, is sent to the hospital because of his serious injury. Then he is reporting about her visiting last night at the airport. Ailean tells Kaiba that there is no interesting news there. Kaiba says that he, in fact, would like to show this video. Openning the tape, Kaiba shows Ailean Yugi's duel against the first game master. Ailean thinks that he is kidding her. Such a little boy isn't her opponent. Kaiba tells her to see it again. The scene is cut to Yami Yugi scene that lets Ailean be amazed. When Yugi is playing game, he changes into another character. Ailean feels very excited to this new interesting opponent.

At Yugi's home, Anzu is happy with her arobic video of Ailean Rao, the top model. Yugi wonders how famous she is. Anzu admires her ability as a good dancer and world class model. Suddenly, a foreigner comes into the store. Sugoroku hopes she can speak Japanese. Anzu notices that this customer looks very smart with good shape. Walking toward Anzu, the customer takes her video and sings her name on it. Anzu is shocked when she has realized that this woman is, in fact, Ailean Rao. Ailean asks Sugoroku suggest her for a game. She needs a game which can play by strategy not luck. Sugoroku thinks that this is such a difficult purchase order. Turning her fact to Yugi, she asks him what type of game he likes. Yugi answers that he likes every kind of game. Suddenly, Anzu jumps over Ailean and says that she is such a big fan of her. Ailean asks Yugi if Anzu is his girlfriend. Yugi's face becomes red and he replies nothing. As a result, Ailean gives Anzu her name card, inviting Anzu and Yugi come to her house and telling them not to forget to bring games. Then Ailean leaves the store.

Later, Anzu and Yugi have reached Ailean's condominium. Anzu gets dresses very beautiful with a bouquet while Yugi has to carry a lot of game stuffs. Both of them come into Ailean's room. There is decorated by ancient stuffs. Anzu knows that Ailean is Canadian-Indian, so she gathers many Indian stuffs for her collections. Yugi takes out many games and introduces them to Ailean. Ailean asks Yugi composite the puzzles for her while she invites Anzu to see her dancing room. Anzu is very happy that Ailean is going to teach her dancing practice. However, when Anzu is posting her body following Ailean's instruction, she is spelled to stop posture and movement. Leaving the room, Ailean locks the door that lets Yugi be amazed. Ailean expresses herself one of the four game masters of Kaiba and challenges Yugi to play a game. If he loses, he will lose an important thing that is Anzu. Accordingly, Yugi transforms into Yami Yugi. In order to play a game against him, Ailean captures Anzu as a hostage. Then she starts explaining the rule of the game, Rijinhai, which is a native Indian chess game. There are the chessmen as following

Chess	Amount	Ability
The lightening god, Indra	1	Beat all, it can be used only a turn. Then it will be removed from the game
Queen	1	Beat only the king
King	1	Highest level
Warlord	1	Beat soldier , elephant and knight
Elephant	2	Beat soldier and elephant
Knight	2	Beat soldier
Soldier	2	Lowest level

In this game, both players must choose a chessman and place it on the board. There is a screen hiding both chessmen from each other. Then a screen is down. Whose chessman is larger wins this turn. He can take his chessman back and reuse it at anytime except Indra, which can be used only a turn and is removed from the game. The lost chessman is removed from the game and can't be played again. Yugi asks how this game will be ended. Ailean explains that there are many ways to win this game. Anyway, she is going to use the simple rule. Who loses his or her king first will lose. Yugi agrees and starts a new game.

Ailean admires Yugi that he doesn't express any feeling from his face. It is hard for her to read. First turn, Ailean places her an elephant while she says that Yugi's chessman must be a knight. Then she is right. Yugi really placed the knight. So Yugi loses his knight at this turn. Ailean asks whether Yugi is wondering something about her trick. Yugi tells her to continue the game. After both of them place their chessmen, the screen is opened. Yugi's chessman is a warlord while Ailean's chessman is a king. Yugi wonders why Ailean uses her king very fast. Ailean asks whether Yugi thinks that she is cheating because here is her room and this is her game. Perhaps, she can read what Yugi is thinking. However, Yugi doesn't believe that. He goes on placing a new chessman. After placing a queen, Ailean chages her mind and changes it into a king again. Yugi's chessman is a knight, so he loses in this turn. Losing three chessmen, he has no knight and warlord left. Yugi wonders if he is being conducted to place a chessman she wants. Next turn, both Yugi and Ailean place a soldier. The result is even, so both of them have to lose their soldiers. Next, Yugi places a queen while Ailean places a knight. Yugi wins this turn. In order not to lose this game, Yugi plans to end it by even. Then the last turn, both Yugi and Ailean place kings, so this game is over and the result is even. Ailean tells him that this rule may be hard to find the winner. So she challenges Yugi to play the real rule. When the kings meet each other again, who has more chessmen left, excluding Indra and Queen will win. Also, if Yugi loses in each turn, he will let Anzu closer to danger. Ailean points Yugi to see a secret door behind Anzu. She has a tiger there. Whenever Yugi loses, the door is gradually opened. Yugi is getting mad because Ailean is overdoing. Ailean tells him that in the past Rijinhai always put his life on death and dignity as well.

Next game starts. First turn, Ailean's chessman is a king while Yugi's chessman is a warload. So Yugi loses in this turn. A door is little opened that lets a paw of a tiger out. Yugi is wondering why Ailean has to let Anzu be in danger. Though she wouldn't have had to capture Anzu, Yugi couldn't avoid playing game against the game masters of Kaiba. As a reult, Ailean may have some reasons for her done. Yugi hasn't realized yet. The more he is worried, the more Ailean can read his thought. Accordingly, Yugi changes his plan. He starts playing the game by his luck. He closes his eyes and ramdomly takes a chessman and lets it fight. Also, he guesses that Ailean's chessman in this turn is an elephant.So Ailean is very shocekd. At this point, Yugi thinks that he can understand Ailean's technique. Once she said at Yugi's store that she didn't link a play playing by luck but by strategy. Rijinhai is a game played by strategy and possibility. So Ailean conducts the opponent's thought by giving condition to him. Then she can easier guess his chessman in each turn. Similarly, Ailean created the dangerous situation to Anzu and let Yugi be in trouble. Then she can read Yugi's feeling and guess his chessman. When the screen is opened, Ailean's chessman is an elephant while Yugi's chessman is a knight. Though Yugi loses, he says that Ailean's chessman is an eleplant as he guessed before. Ailean is amazed by Yugi's thought. Yugi explains that there was 1/9 possibility that he would randomly choose the king from his chessmen. Although Ailean knew it, she would still choose an eleplant, low level chessman. That means Ailean is using her strategy plus possiblility of Yugi's select. Ailean doesn't care what Yugi is analyzing. Game continues. Ailean puts out her Indra while Yugi places a soldier. Though Ailean wins, she has to remove Indra from the game while Yugi loses only the lowest-level soldier. Yugi is reading Ailean's strategy from her feeling and possibility as well as Ailean is doing with him. Ailean hardly believes that Yugi can read her strategy. Rijihai game has had a long history with various strategies for 2,000 years. Next turn, Yugi can beat Ailean's elephant by his king. She is shocked when she has realized that Yugi can read her strategy. Yugi tells her that the real origin of the game is Egypt. Knowledge of all kinds of games is inside his brain. The last turn, Yugi beats Ailean's king by his queen. When the king is lost, Ailean becomes a loser. Ailean accepts her defeat and admires Yugi as a great gamer. Yugi also accepts that she is the greatest gamer of people whom he has ever faced against.

As a result, Ailean releases Yugi into dancing room. Yugi hurries to get into Anzu and sees how she is. However, Anzu slaps his face that lets Yugi change back into little Yugi. Anzu tells Yugi not to interfere her practice while Ailean is smiling at both of them. Ailean turns back to see Kaiba and returns her sign as a game master to him. Kaiba is very mad when he knows that even Ailean was still defeated by Yugi. Before Ailean leaves, she tells Kaiba that Yugi is really a great player. Also, he is greater than Kaiba. So Kaiba is getting more angry. At the airport, Ailean is leaving Japan while Yugi and Anzu are sending her there. Ailean would like to come back and play a love game with Yugi again next time...
