Puppy Love(Yandere!Shigaraki AU)

Quirk:
{Puppy love}: The user emits a pink ray from his hands. Once a target is hit they become the type of dog most suited to their personality. The quirk can only be undone by true love's kiss ie. platonic, friendship, romantic. If the target manages to get a kiss from someone who truly loves them then they will transform back to human form.
[Warning!]: If the quirk is not undone within a month, permanent canine characteristics will begin to accumulate on the target's real body. If the quirk is not reversed within three months the target will lose their humanity, permanently becoming a dog.

Or Shigaraki brings home a new pet.

(Tomura Shigaraki accidentally kidnaps recently transformed puppy Izuku. Read to find out how life goes for Izuku as he lives with the League as their pet.)

All relationships are strictly PLATONIC. There is no romance whatsoever in this fic!!!!
