Azami

A mysterious call girl who happens to visit the hotel the protagonist lives in.

A cheerful and carefree young woman with an ever-present shadow, she ends up being hunted by the yakuza after a client dies on her.

Azami's extraordinary transformation began with a tragic childhood incident. During an assassination mission gone awry, a younger Takeo accidentally shot Azami in the head. The critical surgery to remove the bullet saved her life but had unforeseen consequences. It shattered her brain's natural limitations, unlocking superhuman strength while eroding her moral compass and igniting an insatiable thirst for violence.

To channel her lethal urges and protect innocents, her brother turned her into a vigilante, targeting criminals beyond the reach of the law. Yet, despite these efforts, her sanity continues to unravel. She's teetering on the brink of becoming a mindless predator, indiscriminately hunting any living being that crosses her path.
