Character: Utsuro 382r4h

Utsuro was born containing a high amount of Altana within his body, granting him ageless immortality and high regenerative capabilities. Unfortunately, he was persecuted by a wary populace who continuously tried to kill him to no avail, leading to them becoming more fearful and greater attempts to kill him, sparking a vicious cycle. To cope with the constant suffering and death, Utsuro created multiple personalities. He was then placed in prison and forgotten about for decades until he was able to leave when his cell door rotted away. But at the same time, Utsuro's other personalities took over their shared body and decided to kill people, partially as revenge and partially to strive to become human again. He continued being a serial killer until he was caught by the imperial government, who instead of executing him, decided to make him into an assassin, seeing his potential. So he formed and lead the Naraku for 500 years, continuing to slaughter and kill; yet along the way, developed a death wish.

The original personality watched in the background at his blood-thirsty personas and wanted to fight back and resist them. Thus he created another personality, Gintoki, the original personality decides to act and kills his other personalities, including Shouyou, to become the only mind in his body.
