(Izumi is five and Izuku is four. Overhaul is older in this fanfic as well)
The Midoriya family were celebrating the day Izumi finally got her quirk. They were going to Izumi's favourite restaurant for dinner and of course she had to get Katsudon!
Toshinori unlocked the car and got in with Toshinori by her side.
"Are you buckled up Izumi? Izuku?"
The two replied with an enthusiastic "yes!"
"Alright let's get this show on the road" Toshinori said with a smile.
They were halfway to the city centre when a truck skid to a stop in front of their car making Toshinori slam the breaks hitting his head on the dashboard in the process.
Three men wearing what looked like plague doctor masks walked out of the truck.
"Get the girl"
That was the last thing Izumi heard before passing out.
Izumi tried to sit up but her hands were tied to something.
"I see your finally awake"
"W-where am I-I?" That was all Izumi could stutter out to the mysterious man.
"You won't know me, but I know you... Izumi Chisaki" The man stepped out of the dark revealing his beak like mask and piercing golden eyes.
"All I want to do, is run some... Experiments"
Izumi's eyes lit up in confused fear as the man grabbed a scalpel. That night screams filled the empty halls of the Yakuza base.
