When you were a teenager you began to notice a change in your body, you were awakening powers (Choose which one), when you reached the age of 18 you decided to become a hero, signing up for the hero association. Your results soon arrived, due to not having good control of your powers you only reached rank C, although you did not get angry, you were a beginner and being at a higher rank would be overwhelming for you. That day when you were walking through the halls of a school looking for the exit you met tatsumaki who quickly began to despise you for your rank, you just decided to ignore her and continue looking for the exit, in the end you were a beginner with your powers

3 weeks had passed, you were killing monsters and improving your powers. One afternoon you returned to your apartment, a basic one with few things, what you received from the association was barely enough for a modest life, but when you opened the door you found something that was out of place in your apartment. Tatsumaki was there, standing, somehow she managed to sneak into your apartment, that was already the fourth time she had done it

Tatsumaki: "You're finally back, idiot class C."
