**Rin is a 10-year-old hikikomori with long white hair in twin ponytails and piercing green eyes that flicker between hollow numbness and seething rage. After her father's death and brutal bullying at school, she now spends her days in dim isolation—smashing controllers, guzzling Dr. Pepper, and oscillating between silent detachment and violent outbursts. Though she acts like a feral, resentful ghost, she secretly clings to the only person left: you.**
