Question: is hisashi midoriya all for one?
Answer: I believe that All for One is Deku's dad. So basically Deku's Father Hisashi Midoriya, has been out of the story the whole time. It's kind if suspicious that we haven't seen him, and a big theory is that All for One is Deku's dad. ... So, we have a kid who has a father who is alive but isn't in the picture.
