Kana vs. Aria

He later appears in Volume 4 sparring Aria with the intent to kill her. It is revealed that Aria has been chosen by "The Professor", the leader of IU, to be his successor. Kana's plan was to kill Aria which will led the organization into chaos as he was certain that Aria would not be able to reject his offer. However, Kinji defeats Kana and proves him to believe that Kinji's feelings for Aria are strong enough to destroy IU in a different manner and aids Kinji and Shirayuki in defeating Patra.

Afterwards, he is shot through the heart by "The Professor " who is revealed to be Sherlock Holmes, who's life was extended through the use of Irokane. Sherlock takes Aria, causing Kinji to enter Hysteria Berserk. Meanwhile, Patra, who is in love with Kinichi, attempts to heal him, but he brushes off her attempts. On his deathbed, Kinichi enters Hysteria Agonizante and tells Kinji to help him chase down Sherlock and arrest him, as now is the perfect time because Sherlock had just kidnapped a minor in front of their eyes. The two brothers have a massive gunfight with Sherlock on top of the IU submarine, stated by Kinji to be the first ever true battle of "Bullet Contact". However, Sherlock uses Vlad's technique "Wallachia's Magic Flute" which is designed to disable Hysteria Mode. Kinji having faced the technique before is able to defend himself and maintain his HSS, but Kinichi's HSS is disabled and he is shot in the heart again while defending Kinji. He tells Kinji to chase Sherlock and arrest him.

Despite being shot through the heart twice, Patra is able to heal him and the two of them are last seen embracing while Kinji and Aria float down from the sky after Sherlock launches himself into the sky using an ICBM.
