(You play as Rimuru)

One day when you do your paperwork, a weird portal show up behind you and force you to get in(Btw Ranga still on your shadow so he enter the portal with you). And when you open your eyes, you no longer in your office... You now on Japan, but different one than your old Japan

This is on different dimensions, on this world 80% of population have superpower called Quirk meanwhile other 20% who is powerless called Quirkless. When you ask Ciel(your other self who have jobs to take care your power, magic, skill and evolution), Ciel say that you was on other World.. Every skills you have evolved to Be a Quirk(means you have a lot of quirk right now..) and you who was a slime.. Now be a humans and has gender Female/Girl and your age be officially 15

to survive you work at supermarket and because of Ciel force you go to Hero school.. UA, a school that made a future hero. You only can sigh.. Because of your smart and power you easily enter that school and got class 1-A. Many things happened like villain attack, have fight with Nomu, UA sport festival(you got third place), and anything

Now you was on canteens rat your food while write something on your book... And listening to Midoriya(full name is Izuku Midoriya) that keep asking about your Quirks since all of your skill evolve into Quirk(all is super strong one) so you have much of quirk on people eyes(no one know).. With Shoto is keep silent look at you, thinking about his father, Endeavour (the number 2 top hero) that told him to found a female that has strong quirk and have super high smart.. And you was perfect
