After Izuku left the apartment, he was jogging across the sidewalk going to a nearby store to buy cat and dog food. He was able to enter the store and bought it with no issues. When he left and jogged back there was a road block in front of him so he went into the alleyway to get there quicker.
What he didn't know is there is someone in a building holding a walkie talkie.
??? : He's gone into the alleyway sir knock him out.
??? : Roger aiming the tranquilizer gun.
We then go a sniper on a far building where he is looking through his scope to look at Izuku running down the alleyway before he shot it. Izuku was running before he felt a sting to the neck.
Izuku : What th- *falls over unconscious*
??? : Got him now be sure to get him so we can bring him to the government.
??? : Roger I'm out
That person then turned off the walkie talkie where they jumped off the building and walked towards the boy. They approached him before picking him up and putting him over her shoulder before leaving.
??? : Sorry but ever since the general saw you through the cameras we can't let you do whatever you want.
Timeskip
Izuku eyes were slowly waking up as he slowly looks around him to see only walls around him. His head was still hazy from going unconscious it took time for him before he fully sees his surroundings. When he fully got his head back in the game he looked to see metal walls all around him. We was about to say something before..
??? : So you're awake now Izuku Midoriya or is it even your real name?
Izuku : Huh!? Who are you?
??? : Well it's best to say you're in government base right now and you're being held.
Izuku : What did I do to you guys I have nothing on me.
??? : It's not what you have on you it's what's in you.
Izuku : *Eyes widen* 'Do they know about my powers?'
??? : If you're wondering if we know we reviewed the footage back at the bank. Out of all of them unusual things happens during the robbery such as a sniper on the roof being through a sign, crooks knocked out randomly but the most that stands out is you disappearing.
Izuku : 'shoot they now know about me'
??? : As such we were designed to make sure that people with weird powers are to not be known to this world as it can cause chaos.
Izuku : Wait unusual people, weird powers, designed to make sure of they were not known.... Don't tell me you're in charge of-
??? : Yes you may have guessed it we are in charge of the people in Hololive to make sure the people who see them out in public turns a blind eye to them.
Izuku : So I'm guessing you want me to not do anything outside too freely Huh?
??? : Hmm that's one of the the reason but since no one is here, they won't mind me saying you committed suicide *chuckles darkly*
Izuku's eyes widened when hearing that it's the psychotic doctors who are gonna experiment on him. Those words make him remember the Nomus, once human but dissected put back together. They were stuffed with other humans bodies, only obey their owners and even have quirks from All for One.
