[Main Hunter] About the Fact That I Was Picked Up

I once suspected that I was not the biological child of my family. After all, I just want to mess up, but they love their work deeply. But I never expected that I would actually be picked up. If I could go back in time, I would definitely teach myself a lesson and not eat what others give me. Nothing will happen! PS: The parallel world node of the reincarnated demon, Yotsuba who ate the snacks given by Ilmi. Not only was it returned to factory settings, but the shell was also replaced. Similar to Kaneki Ken's amnesia state. PPS: I will write a general line, divided into different lines. Killua should be the first one, and then look at the others. PPPS: People who are taking the postgraduate entrance examination will only write when they are fishing, and will not join V, so they will update as they please (but I will be more motivated if you leave me a comment) Intention: Listen to your mother
