Burn the witch (edited)

In the world it had quirks and magic users.Magic was known all over the world.Ever since the kid who made light was born magic users started to decrease while quirk users started to increase.The last people who was able to do magic was Rafal and Rhian the brothers of good and evil.

Ever since Izuku did his first spell his father treated him the same way Endeavour treated Shoto you.Both Izuku and Shoto had a bond with each other since they share the same pain,in fact they are best friends they have such a great bond stuff only twins are supposed to do,they can.E.g they feel the same pain of Izuku gets hit Shoto feel the pain.Izuku didn't share that bond with Katsuki,Kana,Shuki and Izumi which is weird considering both of them are twins.
