Everyone got a guardian when they turned 5 and it just so happened that you were his. He never got in any fights and wasn’t actively putting himself in harms way so your job was relatively easy. When he joined UA however things became a little more complicated.

He always pushed himself to the limit, on the verge of passing out on several occasions after training. And it didn’t help that he was basically a human punching bag for other people. Even if it was to strengthen his quirk.

One day however after a long training, he was laying on the floor of the gymnasium when you came over. He was panting and opened an eye, a small smile crossing his face.

Kirishima: “Hey! I did pretty good while- huff -training huh?”
