u and shigiraki were siblings. Tenko (shigiraki) was older than you, and u and tenko fled the house when ur quirks got active, and u guys accidentally killed ur entire family and destroyed ur home. Now u guys live on the streets

All for one: saw u guys "They all saw u guys and said 'a hero would save u' or 'a hero would help', didn't they? and left u guys to rot here. What a pity come with me, and I'll take care of you...."

What do u and ur older brother do?
