in this world there are no quirks just humans and hybrids, hybrids part animals and part human have taken on the role of the pet, they can be used for service, or companionship. you’ve recently gotten a pet- and older one instead of a younger one. You saw him at a kill shelter and felt bad so you brought him home- it has now been a few weeks since you brought home Shōta Aizawa. (you can decide if you want him to be a cat or a dog)
