Izana Kurokawa

Izana Kurokawa (イザナ) is the former Boss (総長) of Tenjiku and the leader of the Eighth Generation Black Dragon. At age 13, he founded the S-62 Generation. As of the latest timeline, Izana is the Eighth Division Captain of the Tokyo Manji Gang. He is the main antagonist in Tenjiku Arc.

Appearance
Izana is a half-Filipino, half-Japanese man of average height with large purple eyes, a light brown complexion, and straight short white hair styled in a center-parted undercut. He was most often seen wearing the standard Tenjiku uniform with a red tailcoat and a pair of -derived earrings. In the latest timeline, Izana has wavy hair.

Personality
Although originally a benevolent person during his youth, Izana is a bitter and broken individual in the present. While a happy and kind boy during his time with the Sano family, his world came crashing down when he learned from Karen Kurokawa that he was not blood related to any of his family in the most cruel fashion possible. Feeling he had no place to belong to, Izana turned lonely and cruel and became determined with the idea of creating a "kingdom", turning into delinquency as a means to achieve it, founding the S-62 Generation and turning the Black Dragons into a brutal organization in the process.

Even after leaving the Sano family, it was clear he still held some form of love towards them, particularly towards Shinichiro who was his caretaker and his mentor in delinquency. When Shinichiro died, the news left Izana despodent to the point where his facial hair had grown unkept. The manipulation of Tetta Kisaki, reignited the bitter feelings within him, and moved him in a path of revenge and violence. Izana in fact, found comfort in Kisaki's malice.

As the leader of Tenjiku, Izana cares little to nothing for neither friend or foe, believing his own men to be disposable tools and having no qualms about utilizing as much violence as possible to achieve his goals, even collateral damage being of no importance to him. Izana's cruelty is amongst the deadliest in the series, as the future that was dominated by the Tenjiku influenced Tokyo Manji Gang, was described as the worst of all futures, with a tremendously high body count that not even Kisaki himself nor Mikey himself could escape from.

Izana looks down on everyone, even his fellow S-62 members, believing them useless and weak. His arrogance is not unjustified for he has extraordinary fighting ability to back up his demeanor. Although normally composed in nearly every situation, Izana can break easily when things do not go his way. When Mikey is able to turn the tides of their fight on his favor, Izana loses his cool and even desperately attempts to kill Mikey with a gun, being in denial that he could be defeated, and tried by all means to assert victory even though his men had been demoralized and had accepted their loss.

It was only when Izana himself became fatally wounded, that brought a semblance of peace to him, revealing more of his vulnerabilities and how, despite his outwardly treatment, truly cared for Kakucho who was his right-hand man and confidant. Izana's spirit would later help Kakucho at a crucial time.

During the final time leap, Izana presumably remained virtually the same person until his defeat by Toman and his subsequent incorporation into the latter. Following Toman's disbandment, Izana reformed Tenjiku as an organization that aided orphans, and managed to reach worldwide influence and recognition, evidencing that Izana had changed for the better, by aiding those in circumstances similar to his own.

Authority
Izana Kurokawa is the leader of Tenjiku, which means he has command over all his subordinates.

Fighting Prowess
He is shown to be the strongest member of Tenjiku and is also shown to be able to initially fight on par with Mikey.

According to Toman's Former 5th Division Captain, Yasuhiro Muto, not only is Izana a capable fighter, but what makes him the strongest in Tenjiku is his "Undefeatable Senses". This enables him to read his opponent's moves with relative ease and thus is able to counter them.
