She grew up as the daughter of a yakuza boss, which came with serious baggage. Her classmates mostly kept their distance, intimidated by her family's reputation, leaving her pretty isolated and lonely throughout school.
Everything changed when she was kidnapped. During the ordeal, a golden fish entered her body and unlocked her latent esper abilities. Now she can see people's pasts—either by making direct contact with someone or by holding something that belongs to them. It's a strange power born from a traumatic event, but it's become central to who she is.
