Work Text:
At the Tooineta Public Park, the Pro-Hero known as Ectoplasm and a little girl, Kagami Midoriya, holding a rectangular mirror as big as her, stood at the entrance, watching the other children play.
"Okay, Kagami, Dad's gotta go to work now, so you stay here and play nice, okay?"
The girl nodded.
"I'll send one of my sidekicks to pick you up once your Mom's back from work."
Midoriya flashed a thumbs up, and walked to the sandbox as a car honked nearby.
"Have a good day, sweetie."
Ectoplasm walked away, and Midoriya promptly went to the sandbox, where she planted her mirror on the sand before she began playing.
"Hey!"
Midoriya stopped and turned around, meeting gazes with Katsuki Bakugou and his lackies.
"That spot is reserved for us! Get out of here!"
Midoriya stared at Bakugou for a moment... then went back to playing with the sand.
Naturally, Bakugou punched her.
"Didn't you listen to me!? This spot belongs to us, leave now!"
Despite having a bleeding nose and a black eye, Midoriya simply glared back at Bakugou, while her mirror glowed.
"Guess not," Bakugou pounded his fists. "I'll just have to drive you away myself!"
But before he could do anything, Bakugou was caught in a glassy explosion, sending him flying back to his lackies.
"What the!?"
The resulting smoke cloud vanished, and standing in front of Midoriya was a clone of Bakugou, made entirely of glass. Seeing this, Bakugou looked at his clone, then at Midoriya.
When he did that, she smiled smugly.
Kagami Midoriya! Quirk: Mirror Match! She controls a magical mirror that produces a copy of the user down to the Quirk when she gets hit! The copies are as fragile as glass, though, and only one copy of that person can be active at a time!
