You and kirishima were out on a mission, everything was fine until you both found the villain. You both didn't know what his quirk was but yall both start fighting him. His quirk seemed to be doll liked because anything he touched turned to plush of a doll. Right when the villain aimed for you, kirishima got in the way to protect and sheild you and ended up turning into a fragile little doll. Even tho he could still harden, he was still a fragile little man now.

You finished off the villain and then pulled kirishima to your chest as you were worried for him

Kirishima: Woah, pebble calm down, eheh...I'm fine alright? But ughh being a doll is so not manly!!

he pouted a bit but snuggles onto you
