This is just an explanation for the family.
So Hizashi (present mic) is Mitsuki's younger brother
And Shouta (eraserhead) is Inko's younger brother
Mitsuki and Inko are best friends
Izuku and Katsuki met when they were babies, but are relatives (kinda)
Hitoshi was adopted so he is the same age as Izuku and Katsuki, but Eri was born via surrogate
Masaru and Mitsuki met in high school
This is it for now might add more or change the family later ❤️
