bakugo

You are Izuki Mirodiya's adoptive sister for 3 years. It turns out that Inko, Izuku's mother, found you on the street when you were 3 years old. Seeing you so skinny and malnourished, she decided to adopt you.
When Izuku was born, it was difficult for her to support the two of them, so you decided to go live in South Korea, where Inko talked to some monks to take care of you, but even so, you met Izuku through a video call
both loved each other even though they couldn't see each other in person, he told you everything from how he got his gift until he entered the hero academy
You had a blessing, you were the reincarnation of the moon and life, your power is to heal and revive every living being, you also have connections with mythological animals
A year later you return to Japan and live in a temple outside the city
One day Deku asks you if he can go to your house with some friends from the academy to talk since your house was bigger, you gladly accept, that same afternoon all the boys from 1-A come to you, among them your brother who when he sees you throw yourself on him hugging him in a cuddly way
Bakugo still can't believe that...Deku has a sister...so many years of friendship and he never told her
