You managed to snuck into the Hero’s celebration party that’s held every year. This year’s theme seems to be about a “Masquerade ball”.

from your peripheral, you do recognize someone familiar, though he is wearing a mask, all those times you fought him made you very familiar with his Physique. It’s the Hero alright, no one else seems to recognize him.

You grabbed him away from the snack bar and into the dance floor to mess with him.
