A clueless Haruyuki is easily beaten by Ash Roller in the duel. During lunch, Kuroyukihime and Haruyuki enter the accelerated world and Kuroyukihime explains to Haruyuki that in order to continue accelerating that he must fight and defeat other Brain Burst avatars. She also points out that the avatar is created based on the thoughts of the user, which in Haruyuki’s case it is his inferiority complex. When Kuroyukihime offers to let Haruyuki return to his normal life, Haruyuki declines stating that he owes her for changing his life. Having agreed to further his friendship with Kuroyukihime, she orders him to learn how to fight. After linking out, Kuroyukihime explains to the students in the dining room that she asked Haruyuki to go out on a date and he rejected it, much to everybody’s surprise. After school, Haruyuki challenges Ash Roller to a rematch and forms a strategy using the information given by Kuroyukihime. Haruyuki starts off with a surprise attack with the intent to stall until time ran out, but Ash Roller obtained the ability to climb walls on his motorcycle making that strategy impossible. A desperate Haruyuki attempts his killer move, the headbutt, but instead he is rolled over by the motorcycle. Haruyuki then figures out Ash Roller’s weakness and lifts the rear wheel off the ground to immobilize Ash Roller since the motorcycle is a rear wheel drive model from the 20th century. Haruyuki headbutts Ash Roller at close range to win the duel. After exiting the accelerated world, Chiyuri sees Haruyuki and Kuroyukihime together and is mad at Kuroyukihime for getting Haruyuki hurt.
