Yu - Gi - Oh ! First Series - Episode 011 Summary . The group learn about the game " Capsule Monster Chess " or " CapMon " for short , when Miho Nosaka obtains a Gacha Box ( a capsule container ) whose capsules are filled with jewelry of Miho ' s fancy . Miho then reveals it was Warashibe , a college student whom she met just recently , that sent it as a present to her . While Yugi briefly explains Capmon to others , Miho expresses her joy of the present , much to Hiroto Honda ' s protest . Soon after , Yugi meets up with Warashibe , with whom he has been a friend for some time now due to their common interest in " CapMon " ( a " " CapMon " buddy " as Warashibe puts it ) , and informs him on Miho ' s reaction on the present . The whole thing revealed to have been Yugi ' s idea in the first place . Warashibe reveals his obsession for Miho , explaining how he saw her briefly through a show window while obtaining new " CapMon " capsules . Ever since , Warashibe has been convinced the two were fated to be together , and keeps referring to Miho as his " " CapMon " Goddess " , and he is dedicated to win her heart , much to Yugi ' s dislike of his extreme reaction . Later that evening , Miho visits Yugi ' s grandfather ' s shop and obtains a minor " CapMon " capsule , intending to send it to Warashibe as a token of gratitude for the present , thinking of Warashibe as a pen pal . However , Warashibe misinterprets the message as a love confession and leads Yugi to his secret base filled with rare level 4 and 5 " CapMon " on the next day . He asks Yugi for his help in order to meet Miho in the most romantic way he can imagine , but Yugi , initially shocked by the idea , tries to refuse , yet Warashibe ' s baby cry soon convinces him otherwise . Yugi and Warashibe then try executing the plan for him to meet Miho , which consisted of Yugi putting on a ridiculous disguise and pretending to be assaulting Miho , allowing Warashibe to save her , which fails miserably due to Miho seeing through Yugi ' s disguise and repeatedly striking Warashibe with her purse , because he was being too direct in his confession . Miho runs away crying out loudly how she does not know anything about " CapMon " , leaving Warashibe beaten and heartbroken . Due to the rejection , he later schemes at his base and wonders what he did wrong , eventually concluding there must be a reason why she refused him , and sets out to eliminate it . The next day , Warashibe disguises himself as a member of the kitchen staff in Domino High School cafeteria , and after concluding Miho rejected him because Katsuya Jonouchi , Hiroto Honda and Anzu Mazaki were in the way , decides to eliminate them by offering them glasses of poisoned water . As a result , all three end up hospitalized in the nursery with a bad stomachache , with only Yugi and Miho remaining healthy . Miho receives a letter from Warashibe , who claims to have brought judgment upon those who interfere with their fate . This infuriates Miho , who immediately asks Yugi to lead her to Warashibe ' s place . Once there , Miho scolds Warashibe , who shows no remorse . After being rejected for the second time , Warashibe proposes they settle the argument with a game of " Capsule Monster Chess " , with the stakes being that Warashibe would leave Miho alone if he looses , but Miho will have to accept her fate as his sweetheart otherwise . Miho angrily accepts . At the start of the game , both Miho and Warashibe take turns in drawing capsules from a dispenser . Miho ends up with a poor set , consisting of three level 1 , a level 2 and a level 4 monster , while Warashibe ' s gets a set of high - level monsters , including three level 4 and 2 level 5 monsters . Despite claiming to have studied the rules of " CapMon " , Miho ends up pushed in a corner and Warashibe easily takes out one of her monsters on the first turn . Angry with the resulting table , Miho yells at Warashibe and accidentally pushes Yugi into the capsule dispenser , which tips over and breaks . This exposes a hidden device that Warashibe had installed to alternate between high and low - level capsules , which had resulted in him getting much stronger capsules that Miho . Realizing that Warashibe cheated , Miho declares herself winner and tries to leave with Yugi . Warashibe attempts to block their exit , by dropping a portcullis . However the mechanism malfunctions and instead results in a large beam dropped on Miho and Yugi . As the dust settles , Dark Yugi emerges with Miho in his arms , much to Warashibe ' s surprise . Dark Yugi challenges Warashibe to a Game of Darkness . Dark Yugi agrees to continue with Miho ' s current set field and set of monsters , which Warashibe reluctantly agrees on , and is impressed how the Game of Darkness made the monster figures come to life , and one of each of their monsters already annihilated each other . Warashibe then destroys another one of Dark Yugi ' s monsters with Dinosaur Wing , and after Yugi makes a turn by placing his next monster without attacking , Warashibe destroys it with Head Sucker , leaving Dark Yugi with only one monster left . Claiming to have won the match , Warashibe is then asked to look at the field , and he realizes all his monsters were aligned in a diagonal pattern , which is what Dark Yugi was counting on . His last remaining monster is Torigun , who despite his otherwise low rank and limited battle qualities , possesses a special skill that goes in Dark Yugi ' s favor : it can move and attack in a diagonal pattern , and destroy any monster it comes across , even if it ' s a level 5 . With this move , Toribe destroys all of Warashibe ' s remaining four monsters , winning the game for Dark Yugi . Warashibe is shocked by the outcome , with Dark Yugi telling him how " CapMon " is not something to be collected , but played with , and know how to win using every monsters ' ability . Warashibe becomes struck with rage , and after flipping the table in frenzy , he still demands for Miho to become his , for which Dark Yugi inflicts a Penalty Game on him , capturing him inside a massive monster capsule , before leaving with Miho . After Yugi and Miho ' s friends recover from their poisoning , they discuss how it is better now with Warashibe off the scene . While Jonouchi complains that he never wants to hear about " CapMon " again , Miho comes cheerfully running . She trips and falls , revealing her purse was full of " CapMon " .
