An intruder in the boys' locker room.

Meanwhile, with Izuku.

Izuku: It's good that the principal told me that the modifications to my suit are complete. I hope Hatsume didn't add unnecessary things again.

As I arrived at Power Loader's classroom, Izuku stood still just before opening the door, remembering all the times he'd wanted to go in and something exploded.

Izuku (nervous): W-well, Principal Nezu told me Hatsume-san shouldn't be here today, so it shouldn't be a problem if I open the door, right?

Izuku reached for the doorknob, hoping it wouldn't explode when he touched it. When he touched it and it didn't explode, he sighed and opened the door, seeing only Power Loader in the room.

Power Loader: Midoriya, I was waiting to give you your suit.

Izuku: Thanks, sensei. Sorry I got caught up discussing my training with Principal Nezu.

Power Loader: Midoriya, for your sake and the others', I hope you don't hang out with the Principal. We've already had enough with the Principal's behavior without someone starting to behave like him.

Izuku: Don't worry, sensei. We were just talking about what we would do to be ready for the next villain attack.

Power Loader: Well, what matters to us is your suit.

Izuku: Speaking of which, where is it?

Izuku thought his new suit would be in a briefcase like the previous designs, but Mei and Power Loader had created a suit that would fit Izuku's body at any time and with enough technology to be stored in a bracelet.

Power Loader: Mei managed to create a device that stores your suit in this bracelet…

As Power Loader explained Mei's invention, the door opened, revealing the girl, sweating, tired, but with a smile on her face at being able to create new "babies," as she called them.

Hatsume: I've already finished all the homework Sensei left me, it's time to keep making more babies.

Izuku and Power Loader turned to look at her. Power Loader couldn't believe she'd already finished all the homework she'd given him. After all, she'd given him enough to spend a week doing just that, but the young woman in front of him had finished it in a matter of hours so she could keep inventing things.

Power Loader: I think it'd be best if you left before she makes you her test subject. Here's everything you need to know. I recommend you don't read it until you're in your class locker room. Since it's only a prototype, it still has some flaws, and there are two in particular that you should look at in detail.

Izuku: Okay, sen…

Hatsume: Midoriya, it's good that you're here. There are some babies you have to try.

Izuku: Thank you very much, sensei. I think I should go before Hatsume-san catches up with me.

Power Loader: Don't worry, I'll distract her. Mei, before you do anything, I have to make sure you've done your homework properly.

Izuku stopped listening to what they were saying as he walked away to the boys' locker room.

Izuku: I must thank Power Loader-sensei for distracting her. Otherwise, who knows how long Hatsume-san would have let me go.

Setsuna (thinking): He's finally here. It's time to see if what Yaoyorozu says is true. I should have brought my cell phone. No matter how big it is, I wouldn't mind having a picture of her amazing naked body.

Izuku: Now I have to see what this paper says, (reading the paper) WHAT?!!!

Izuku began to read what it said, not seeing anything alarming until he reached the bottom of the page where it said "warning" in red capital letters.

Setsuna was surprised to hear Izuku screaming, so she went closer to see what the paper said, thankful she had good eyesight so she could read it without Izuku noticing.

Setsuna (thinking): I think today is my lucky day. I'll be able to see his body perfectly without anything in my way.

Izuku read the paper over and over again to make sure he hadn't misread it.

Paper: Warning: Wear the suit completely naked. If there is any type of clothing, there could be a malfunction and the suit won't fit the user properly. When you finish using it, or in case of a malfunction, the suit will create its own underwear, so don't worry about ending up naked in public or around people.

Izuku just sighed in resignation as he undressed, unaware that someone was spying on him. She couldn't believe what she was seeing. She was so surprised that she couldn't keep quiet. Unfortunately, her body was with her other companions.

Setsuna: Holy crap, it's huge!!!

All the girls in both classes stared at her, not knowing what just happened.

Kendo: Are you okay, Setsuna? Besides, what is huge?

Setsuna just stared at her, her face reflecting total shock, unable to believe what she had seen.

Setsuna: I-I'm sorry, Kendo. I just remembered I haven't done a lot of my homework these past few weeks, and now I'm there is a lot.

Kendo: O-Okay.

Kendo (thinking): But yesterday we all got together to do homework together, and you were the first one to finish.

Setsuna: By the way, Yaoyorozu, I think your thoughts were wrong.

Yaoyorozu: What are you talking about, Setsuna-san?

Setsuna just looked at Yaoyorozu with a mocking smile and said nothing else.

Back with Izuku, he had already activated the device Mei created, revealing a suit very similar to the one he normally wears. The only difference is that since it's a suit that fits completely to the body, his muscles are more prominent.

Izuku: So this is why I shouldn't be wearing anything when using it.

Izuku looked around the suit, seeing that there was more protection around his crotch, making it safer for the hero, so his groin wouldn't be hurt.

Izuku: This would have helped me a lot when Kota punched me in the crotch. Although the design might not be as good, I can't strip everywhere to put on the suit.

Izuku left the locker room without noticing that on the back of the sheet was another important notice. Unfortunately for him, someone else noticed and went to see what it said.

Setsuna (thinking): So it's just a prototype, and to think it would have such a huge flaw, I hope Midoriya didn't see this, so I can let everyone see Midoriya's true size, although I wonder if I should keep this information to myself.
