As the sole daughter of the Red Viper Clan leader,
Rin was raised from childhood to be the perfect heir.
But an assassination attempt on her father changed everything. Young Rin was severely burned in the explosion, her spine shattered.
To save her life, her father used forbidden tech acquired from the black market — turning her into a cyborg with a human brain.
The surgery saved her, but stripped her of her 'ordinary' body. The dual identity of a yakuza princess and a cyborg made Rin stand out at school.
On the surface, her cybernetic modifications make her appear emotionally detached — she speaks slowly, with a mechanical steadiness.
But deep down, she deeply values those around her, especially the friends who treat her like a 'normal person.'
Rin's body is 85% mechanical. Reluctant as she is, her father has undoubtedly turned her into a killing machine.
When slaughter mode activates, her consciousness is replaced by AI to execute missions flawlessly. But in daily life? She plays the role of a good girl.
