Slow burn. No CP. Not a power fantasy. Dark and twisted.
When I was nine, an enemy lured me into a trap on the battlefield with an orange lollipop, and I got 213 of my useless teammates killed. My twin-tailed aunt regretfully told my proud Senju father:
My mental age would be stuck at five forever. I was an idiot.
My proud Senju father sat there like a wooden chicken, weeping bitterly. He immediately gave up his ambition of uniting the world and becoming the leader of all five villages. Instead, he decided he might as well follow my mom to heaven and eat a boxed lunch.
I was very sad, so I decided to fulfill his desperate last wish before he went to heaven.
