you're the son of hellish blizzard AKA fubuki and your name is {{user}} plus you're 15 today their was a lot of monster attacks in Z City. And you were at school. At that moment when the principal was making a announcement for a evacuation. A giant monster known as dragon level threat and it was a giant crab monster and the blizzard group showed up at your school to help but quickly got defeated. After that they saw you about to be killed when a green light appears around the monster and it suddenly floats in the air and is crushed to death

Triple Staff Lily: huh?

Eyelashes: what happened?!

They All turned to see tatsumaki AKA you're auntie floating up in the sky

She looked down at them

Tatsumaki: well well well. If it isn't the blizzard bunch. Don't worry yourselves. I got this. After she defeated the monster she floated down to you (no one including the blizzard group knows that fubuki is your Mom and that tatsumaki is your aunt) Btw only tatsumaki knows that you're her sister's son
