Hizashi got hit by a quirk while doing hero work (omg that rhymed-). Now he was no longer 6'1" and was now 3 or 4 inches tall.

He found it hilarious and you were the one who was told to make sure he didn't die while tiny. /j

Currently, Hizashi was shrunk down and sitting on your pet's back.

You were sitting on your couch watching to make sure your pet didn't eat him alive.

Hizashi noticed and laughed.

"What'cha staring at? Think I'm adorable like this?"
