Prompt: A good prompt idea would be to have cannon deku switched with this one due to a quirk and see how everyone deals with a different deku (and how fed up everyone in cannon gets with Izu)
Yes, I already did this.
However, now we are going to see what our old man was forced to go through!
After Writing: I tried. Shouta is weird to write for me.

Shouta's POV

Izuku, what did you do this time? I was taking a nap, and I get a call saying that he is playing another one of his jokes.

Can't the kid give me a break?

I enter the police station, and the receptionist, who knows me way too well because of Izuku, nods at me to go to the detective's office. When I am outside, I knock on the door before entering.

Inside, I see Detective Tsukauchi leaning against his desk, and Izuku is sitting across from him rather calm. Usually, he doesn't bother to sit; he stands around and starts messing with shit like he shouldn't. The detective looks up at me with relief.

Izuku turns around with a confused expression, and he looks very different. Rather than this black costume he has, he is wearing a bright-green bodysuit with barely any signs of his technology. His facial expression shows nothing of what Izuku would be showing right now. He may be able to act but never to that extent of innocence. It's his first sentence that confirms that something is wrong.

"Aizawa-sensei, w-what's going o-o-on here?" Damn it, problem child. What the hell did you do this time? On instinct, I use my quirk on Izuku, expecting it to be Toga.

I throw my scarf at the Izuku imposter before I freeze as I realize two things.

First: This isn't Toga, and whoever this is has a quirk.

However, the second is what has me worried: Izuku isn't here.

"W-what's going on?!" The imposter-Izuku asks as he trembles in place.

I glare him down, "I want your name, quirk, and where Izuku is."

"Midoriya Izuku, super-strength, and I am Izuku!" The kid rushes out nervously. I remain quiet for a moment.

"Detective, what was Izuku doing before he came here?"

Detective Tsukauchi takes a moment to remember everything, "Izuku was arguing with a hero to try and get them to fight the villain Miss. Universe as the hero had a more effective quirk for the job. However, like most heroes, he wouldn't listen so Izuku went to fight her himself. During their fight, there was a light, and we got whoever this is. This Izuku got away from the fight, and the heroes dealt with it. We don't have much else besides that Patchy is under your control due to the owner being too far away and we don't know Miss. Universe's quirk."

Izuku had to get hit with a quirk. I look over at the new Izuku- or Midoriya I guess he goes by- to see him trying to look at small as possible.

I sigh, " Midoriya, what were you doing before you came here?"

Midoriya perks up, "Oh, w-we were doing a b-battle trail, s-sir. S-suddenly, I appeared here." I think I have an idea of what is going on here based on the villain name and Midoriya's reaction. However, I need more information.

"What's your relationship with me?"

"T-teacher, sir. Sensei, w-what's happening?" Detective Tsukauchi seems to realize what I am getting at, but he lets me explain.

"The current assumption is that the Izuku here got hit with a quirk that switches him with Izuku of another universe, and you happen to be the one he switched with." Tsukauchi starts typing on his computer, probably filling files.

"O-oh." This Midoriya is so meek that I don't have a clue how Izuku became how he is.

"What should we do then?"

Tsukauchi rubs his forehead, clearly tired of Izuku getting into these circumstances, " Izu- Midoriya, you go to UA, correct?" Midoriya nods quickly, " Aizawa, I'm sorry, but can you take him for a bit? I'll figure out a way to send him back." Damn it.

"Fine. Let's go, Midoriya." Midoriya quickly reacts as he stands up to follow me. After some paperwork, we step out, and I start leading him to UA.

Due to Izuku being a recognizable figure, I have to lead him through backways to avoid getting us caught by the media. Unfortunately, that doesn't

"A-Aizawa-sensei? W-why d-d-do you refer to me as my g-given name? Also, w-why are people watching me w-weirdly? I u-usually get d-different looks due to the S-sports Festival."

I figure it wouldn't hurt him to know about a place he can never return to logically, "In whatever that idiot would call it, you and I are very close here. As for the looks, you constantly fight the media for hero rights because you're quirkless. Anything else?"

The whole time, Midoriya watches me with a surprising look before turning his eyesight somewhere else, "N-no!"

This is going to be long, isn't it?

"OH MY GOSH, YOU ARE SO PRECIOUS, " Hizashi blasts with his quirk to Midoriya, so I had to cancel his out, "Wait a moment, come here, Midoriya!"

I watch Midoriya approach Hizashi, and I realize why he did that.

"This Midoriya is taller than ours!" Hizashi exclaims.

"H-huh?" The kid must not be used to the attention. Meanwhile, Izuku begs for it like a dog.

"A little difference, but Izuku will be pissed when I tell him this!"

Nemuri grins, "He is more adorable too. He has this innocence to him."

I sigh, "Don't tell the brat. He's already going to go on a rampage when he gets back. If he learned anything, he probably figured out that this Izuku has a quirk. That's going to kill him."

Nemuri and Hizashi stare down Midoriya before Nemuri ask, "What's your quirk?"

"S-super-strength," He replies. I still haven't gotten over the fact of how nervous this kid is. The anxiety of Izuku not being here at all isn't helping the situation.

"Ooo, can you show us?"

I consider my options before looking at the two, "You two are in charge of him. Don't let him get hurt."

With that, I go take a nap.

"What do you mean Midoriya broke his arm?" I snarl as I make my way to Recovery Girl.

Nemuri follows quickly after, "Apparently if he overdoes it, he broke all the bones in his limb." And he hasn't found a cure for that?

"And what lead him to that circumstance?"

"We decided to fight him. He's a good fighter, but he needs work!"

"Are you kidding me?"

"Apparently, it's normal. That's why he has scars all over his arm." If the other Aizawa can hear me, I wish you luck with him.

Thankfully, we have Recovery Girl to take care of him.

---

"I-I'm s-s-sorry!" Midoriya stammers when I arrive.

"That's not conventional for a fight. It would make you a liability." Izuku may do some stupid things in battle, but he doesn't get himself injured like that. Well, physically. Mentally is another story.

"I-I know..." At least the kid feels guilty.

"Come on."

---

Good news: Midoriya has a sleeping schedule.

Bad news: I couldn't sleep because I am worried about Izuku. He's probably starting shit in the other universe, but it doesn't stop me.

Please give me back Izuku today so I can lecture him about being an idiot, and to keep wherever he is alive.

I got a message this morning from Tsukauchi saying that the two will be switched back after24 hours. That's something.

---

I don't want to know how Izuku got germaphobia when this one is not as clean. He isn't a slob, so that's something.

It's odd not to hear the kid screaming some stupid song he learned while cooking. Midoriya works out instead.

---

"As much as I appreciate the calmness, I want the brat back. Hopefully, he didn't mess up your universe too much."

"W-what?!" Before I get a chance to respond to Midoriya, the light appears for a moment, then disappears to reveal Izuku.

I don't bother to stop myself from hugging him.
