Tatsuhiko Shibusawa/Synopsis

Dragon's Head Conflict
Six years ago, the Special Division for Unusual Powers summoned Shibusawa to stop the Dragon's Head Conflict that had been raging for 88 days, but instead, Shibusawa used the opportunity to further his own goals. Somehow, he developed his own organization. He targeted a jewelry store and stole the gemstones, killing every ability user guarding them, including an accomplished mercenary who fought in the war and the leader of a group within Gelhart Security Service (GSS).

Right before Shibusawa took his leave, Sakunosuke Oda arrived at the scene after receiving the news, claiming Shibusawa must be a newcomer to Yokohama because the latter didn't know that the jewelry store was a depository for the GSS, a powerful criminal organization who abstained from participating in the feud. Shibusawa then hinted that the culprit was the White Kirin, whom Oda knew from reports as an ability user who came a few days ago and had been attacking all organizations involved in the conflict. After Shibusawa departed, Osamu Dazai contacted Oda that the man he just talked to was the White Kirin (白麒麟,), the man planning on taking over the feud.

Over the course of the conflict, Shibusawa had managed to dismantle various organizations, including Strain, one of the four biggest international crime syndicates; Takasekai, whose leader's assassination left their chain of command in chaos; Shadow Blades, an illegal arms dealer; Bishop's Staff, a former religious group; and KK Company, a smuggling group. Furthermore, he also killed one of the Port Mafia's executives aliased the Colonel, leaving an opening in the Mafia executive position.

On the 72nd day of the feud, Shibusawa was ambushed by Dazai and various mafiosi in an elaborate setup. Dazai urged him to surrender, telling Shibusawa that he is a nullifying ability user. Shibusawa advised him that he himself was the only chance of ending the feud, which he planned to accomplish with another feud. An explosion suddenly took place in the Mafia headquarters and collapsed it; Shibusawa revealed that he was not working alone and declared all-out war on all criminal organizations. Sometime after, Shibusawa occasionally met Fyodor Dostoevsky, who advised him to move on with his next targets if his erstwhile plots bored him.

Towards the end of the conflict, Shibusawa's group captured six of the Mafia's men, along with Dazai who purposely allowed to get caught. The latter eventually got retrieved by Chūya Nakahara, and they soon reached Shibusawa's Draconia room, finding him burning gems and alternating between "It will be mine" and "It will not be mine". Bored out of his mind, Shibusawa languidly informed Chūya that his comrades killed themselves. Enraged, Chūya activated Corruption, with Shibusawa presumably getting caught in the ensuing destruction.

Nonetheless, the government protected Shibusawa and even covered up his crimes overseas, as they deemed his ability a valuable asset in counteracting a possible gifted nationwide invasion.
