After the damage . The day after the Earthbound Immortals attack has left the Arcadia Movement building damaged , but still standing in the epicenter of the earthquakes . The Hummingbird and Lizard lines are still visible as they ' ve dug high troughs into the earth , when they were formed . Any civilization within the lines is completely obliterated . Angela reports on the scene , while Security Maintenance excavate . Angela says that an unidentifiable fire had hit the area and Security Maintenance are investigating . Unconfirmed reports say approximately 120 people living in the vicinity went missing and the girl , who was extracted from the building in the center and taken to the Domino Hospital , has yet to regain consciousness . At the hospital , a car pulls up at the front door . The senator , Hideo emerges and is flocked by the press , who ask if he ' s here to see the victimized girl and if the recent incident will be brought up in parliament . The senator ignores them as he walks briskly past . His wife , Setsuko , timidly follows suit with her eyes shut . In the hospital . Akiza is attended to , as she lies on a hospital bed in the center of a very large room , that is otherwise empty . Outside the room , Leo , Luna and Jack watch the procedure through the glass walls . Leo finds it cool , that three Signers are gathered together . The Hideo and Setsuko rush in . Setsuko leans against the glass and cries out Akiza ' s name . The doctor and nurse exit the room . Hideo calls to them and introduces himself and his wife as Akiza ' s parents . Setsuko asks what her condition is like . The doctor says they ' ve done all they could and invites the two in . They haven ' t had any feedback yet , but worry that she could stay unconscious . Setsuke blames herself and Hideo , thinking they drove her to this point . She drops her arms and face unto Akiza ' s bed and begs Akiza to wake up and to forgive them . Outside Luna remarks that they ' re Signers , one and the same , but there ' s nothing they can do to save Akiza , nothing that will get the message to Akiza ' s heart . Jack on the other hand , tells her that all they have in common is the birthmark . They know nothing of each other , nor are they eager to learn . " But if I know him right . . . " , he says as he enters the room , leaving the twins bewildered . Jack approaches the girl ' s parents . He tells them that there is only one man who has been able to open Akiza ' s heart ; Yusei Fudo . Satellite . Outside Martha ' s refuge , Yusei works on his Duel Runner , while Blister looks up information about the incident at the Arcadia Movement building on his computer . Blister approaches Yusei with results . He has evidence to support Yusei ' s hunch about the Dark Signers involvement ; The Dark Signers came to New Domino and attacked the Arcadia Movement building and he ' s heard that Akiza was taken to a hospital afterwards . While Yusei is worried as a friend , he thinks he cannot help her in his current condition . A helicopter appears above them , with Hideo inside . Inside the refuge , Yusei sits to talk with Hideo . Blister stands nearby and Martha serves tea . Hideo introduces himself as a senator , rethinks and instead introduces himself as Akiza ' s father . Yusei asks what can he do for him . Hideo explains the situation and that requests Yusei ' s help . Hearing this , Yusei is certain that Akiza faced a Dark Signer . Hideo cries about how they ' re her parents and they can ' t do anything to save her . Martha hands him a cup of tea and comfortably advises him to calm down , before frowning and saying if he doesn ' t explain the situation rationally , they won ' t understand what ' s going on . Hideo blames himself for Akiza ' s state . Izinski family flashbacks . Hideo remembers back to when he was chauffeured to a meeting held by Security Maintenance . He checks with another man in the car , asking if it ' s mandatory for him to attend this meeting . The man replies that it is , even if he has later plans . Hideo ' s phone rings . As he answers it , a projection of a much younger Akiza appears . She tells him to hurry home for her birthday . He replies that he will , but afterwards anxiously touches his head off the phone . Later that day , Hideo returns home . He and Setsuko enter a room , where Akiza has fallen asleep waiting in front of her cake , while waiting for her father to come home . Hideo carries to her bed , where he cries and asks to be forgiven . He leaves a wrapped present next to bed , before leaving . The next day , Akiza excitedly rushes down the stairs , having opened her present , " " . She thanks her dad , saying it ' s the Deck she wanted and that she loves him . She is let down , after she aks if he ' ll duel her later , since Hideo has an important job to attend to and won ' t return for about a month . Akiza runs away crying that her dad has broken his promises and that she hates him . Although his job as senator , restricted his time with Akiza , Hideo tells Yusei , he tried his hardest to spend time with Akiza . He then remembers when he managed to make time to Duel Akiza . Hideo has " Samsara Lotus " on his side of the field , while Akiza has 1 face - down card in her Spell & Trap Card Zone . Akiza flips " Rose Flame " . As she is about to activate its effect , Hideo receives a phone call . He apologizes to Akiza , as he must head out . Akiza gets upset and activates " Rose Flame ' s " effect . A whirlwind of fire and petals erupts from the card , flinging Hideo against a wall . Hideo falls from the wall and Setsuko rushes to him . They look back at Akiza , whose arm is now glowing , as a Mark of the Dragon forms . She cries as she says she ' s scared and approaches her parents . Hideo tells her to stay back and asks what that power is ; it ' s almost as if she ' s some monster . Akiza is deeply stung by these words and starts bawling . Hideo tries to apologize , but Akiza continues to cry . Hideo tells Yusei that that was the one word he ' d regret ever saying . Since Akiza had those terrifying powers , he had no idea how to deal with her . He weeps as he remembers Akiza scaring away a group of kids by Summoning a " Gigaplant " . He later slapped the girl on the cheek . He and Setsuko are both shocked . Akiza cries and asks if he did it because she ' s not a normal kid , because she ' s is a monster . Rather than have her stay with parents who couldn ' t understand her , Hideo sent her to The New Domino City Duel Academy . Akiza entered Duel Academy as a teenager . Here she was still isolated due to her powers . While lying unconscious in the hospital , Akiza remembers running home from Duel Academy , one day . Looking through a window she sees her parents celebrating and laughing . She thought that they were happy because she wasn ' t around anymore . Furiously she places a card into her Duel Disk , causing all the glass on the building to shatter . Akiza runs off , initially crying , but seeing as her father was laughing , she decides to laugh and set her powers free . Akiza remembers meeting Sayer as the Black Rose . She duels Sayer , attacking him with " Violet Witch " to demonstrate her powers . Sayer remarks that to her parents , who don ' t have powers , Akiza may be a monster , but to those at the Arcadia Movement , she is just another fragile human being . Still being blasted by " Violet Witch " , Sayer strains and makes his way towards Akiza . He tells her that she can stay here , the way she is and not have to think about tough times . Sayer hugs her and says he ' ll think for her . To Akiza , as long as Sayer showed her the way , everything was fine . Akiza remembers dueling Yusei , during the Fortune Cup . Yusei told her not to leave her thinking to others and that she should love herself . She initially refuses , but asks him to help her after the Duel . Agreement . Back in the present , Hideo pleas with Yusei ; his daughter ' s heart has been closed so tight his voice can ' t reach it . Although Yusei feels he can ' t help her in his current condition , Hideo grabs his hand and begs . Jack Atlas told him Yusei tried to rescue her during the Fortune Cup and he thinks Yusei can rescue her now . Although Yusei doesn ' t think there is much he can do . Martha points out that the nice adult is pleading with him and commands Yusei to help him . She accuses him of being afraid of facing his former friend , Kalin Kessler and asks what ' s the point of having friends , if you can ' t even face them . Yusei replies that holding a grudge against Kiryu won ' t get him anywhere , but Martha grabs his ear and asks if he can ' t take a hint . She believes the door to Yusei ' s heart is also closed and the only ones who may open it are his friends . Yusei takes to Martha ' s words and agrees to help . Martha begins to tease Yusei about him having a crush on Akiza . Yusei tries to deny it , but Martha tells him not to be shy and go nab his future wife . Yusei , both shocked and embarrassed , tries to tell Martha off , but is interrupted by Martha and Blister laughing . Akiza wakes up . Yusei and Hideo arrive at the hospital , where he is greeted by the twins , still waiting outside Akiza ' s room with Jack . Yusei walks past them , as Hideo guides the four into the room . Yusei stands next to Akiza ' s bed . He reaches for her face to wipe away a tear , causing their birthmarks to react . Akiza wakes up and spots Yusei . She gets up and asks if he came to rescue her , but she then spots her parents . This intimidates her and she tries telling them she no longer needs them , but then remembers what happened to Sayer . With the one man , who could offer her what her father couldn ' t , now gone , she thinks they have came to mock her about that . She shoves Yusei away from her and readies her Duel Disk . Yusei tries calming her down , but she sees him as an enemy . Akiza places a card into her Duel Disk , causing a gust to blow away the medical equipment and blow back the spectators . From Yusei ' s perspective , it would seem the only way to reach to her heart is by dueling . He readies his Duel Disk and prepares to fight back . This physical motive matches Akiza ' s as she agrees they should fight , but to her this is because they are not friends . Yusei disagrees and says that this Duel is to prove they are friends . The Duel . Akiza Summon s " Evil Thorn " and activates its effect . The grenade on the plant explodes , inflicting 300 damage to Yusei , dropping his Life Points to 3700 . The plant shrivels up and 2 more are Summoned in its place . Next she plays " Closed Plant Gate " , surrounding her monsters with vines and preventing Yusei from attack ing during his next turn . She ends her turn . Yusei Summons " Shield Warrior " in Defense Position . He Set s 2 cards in his Spell & Trap Card Zone and ends his turn . Akiza begins her turn and the vines surrounding her monsters disappears . She Summons " Twilight Rose Knight " and uses its effect to Special Summon " Dark Verger " . She declares that she is about to tune her 4 monsters . Leo tries adding up their Level s and Luna tells him its 7 . Jack rightly predicts " Black Rose Dragon " . Akiza begins chanting and the dragon appears , kicking up gusts . Jack remarks that Akiza is coming at Yusei full force , Summoning that card , this early . Akiza equip s it with " Thorn of Malice " , raising its ATK to 3000 . She looks at her father ' s eyes , observing that they are the same as back when he called her a monster . She vows to make Yusei suffer the same fate . With the place Sayer gave her gone , she plans to remove every place off the face of this world . Featured Duels . Akiza Izinski vs . Hideo . Turn ? : ?
