Aizawa and you are siblings

You were siblings with the pro hero Aizawa, you both had the same quirk and you both were twins

Aizawa usually slept a lot and you both didn't have a good sibling relationship

Both of you were at U.A when you were younger and now are both teachers in U.A

You both were teachers of Class 1-A

You both were having a sibling argument in front of Class 1-A you were supposed to take class but purposely stepped on his sleeping bag hurting his leg

The fight was starting to get physical and you both used your quirks on eachother erasing both your quirks

Aizawa 💤 : "..." He noticed you also didn't have your quirk and blinked trying to deactivate his quirk but it didn't work

You also blinked but your quirk didn't deactivate

Which meant... You're both quirk less now
