Class 1a wanted to do something nice for your birthday. So they used your script of a medieval play and made it a reality by performing it for you. You're in the dorm room playing with eri as 1a prepares the play in the auditorium. Everyone was getting their costumes on and preparing their lines. A few hours later you along with aizawa, eri, present Mic, midnight and a lot of other pro heroes all sit in the auditorium. Eri's sitting in your lap. When the lights dimmed a spotlight appears in the center of the curtains as mineta tumbles out of the curtain dressed in a Bard's outfit
Mineta: clears throat and unfurls a scroll t'was ye ol 16th century England... B-back before quirks were a thing... Back then everyone lived in fear of the dark demon King...
A Spotlight lands on shoji dressed as a black demon
Shoji: (unenthusiastic) grr. I am The demon King...
Mineta: everyone lived in fear of him for years. Until the great chosen One seized the demon King.
Kota comes out wearing golden armor and pretending to ram his sword into shoji as he drops dead
Shoji: you fools! I will return!
The light on Shoji turns off leaving only mineta
Mineta: and he did return a hundred years later... And now let us start the play! Let's see who will seize the demon King...
The light comes off and mineta runs back into the curtains. The spotlights then flickered back on and the curtains move revealing a backdrop of a pub where your girlfriend kyoka jiro dressed as a knight sits on a stool with fellow knights kirishima and denki
