Kuro POV:

Master was feeling down and I had a good idea on how to cheer him up but I was sure that the others wouldn't like that at all. We were in his room and waited for Master to come out. It didn't take him long to shower and change into his uniform.

Me: Master you ready?

Izuku: Yeah, but what are you planning, Kuro?

Me: You will see.

Fenrir: Something tells me that we will regret this.

Me: Nah, not at all. Now teleport us into the classroom.

Fenrir: Do not order me around you little fox.

Me: Ohh I am not scared of a big bad wolf like you!

Izuku: Guys, Enough! Fenrir, please. I don't want to be later than I am already.

Fenrir: Yes, Master. Immediately.

With that, we were directly teleported into the class room. The moment we were in, I concentrated on each and everyone's connection to the darkness. Once we were in the classroom, Fenrir disappeared and I was left with my master alone.

Me: Master was here all the time, you just didn't see him! You also can't see me!

Izuku: Kuro?!

Me: What?! No one ever said anything about me not being allowed to brainwash them all.

Izuku: ... This feels wrong.

Me: No, besides Nezu will tell Aizawa about what happened. I also don't want them to think you are sloppy on your first day. Besides it was kinda our fault so let me at least clean up our mess.

Izuku: Aww Kuro?! Thank you.

I saw master go to his seat. He was right behind Bakugo but in front of Hitoshi.

Hitoshi: Say Izu, How long have you been here?

Izuku: Just came in.

Hitoshi: What?! I didn't see you at all.

Izuku: That's because of Kuro. He used his ability on everyone. I will tell you what happened later.

Time to mess with them all!

Me: Hihihi

I went to the seat number one.

Ohh someone likes blinky stuffs.

Me: You lost your sparkle, glitter boy!

Nothing beats a little bit of mental fun, right?

The moment I said that, I could immediately see the effect taking place.

Sparky: Oh no no no no no no! Le sparkles?! Gone! NO! MY Glamour! GONE!

He immediately took out a hand mirror and began looking himself ito it and I could see him tear up.

Ok next one that Alian!

I jumped on the next desk right beside him.

Hmm what should I do with her?

Oh I know!

Me: Do the Dame to Consita Dance!

This sure will be fun!

In the next moment, she stood up and did exactly what I told her to do.

???: This is not heroic. I must ask you to stop whatever you are ding and sit back down.

Ohh foureyes, you can't wait till it's your turn...

I went to him and since he was doing some robotic motions the whole time, I thought it would be funny to have him behave like an actual one. On top of that he looked like he wanted to dance too-

Me: You are a humanoid! A robot in disguise so behave like one and do a robot dance too!

He was already standing and doing something with his hands but now he was more robot like.

Mission accomplished.

I could hear Izuku and Hitoshi laugh but I was not done at all.

Me: Yo, you frog behave like one! Find the fly!

The girl jumped on the table and began doing some frog noises and she began jumping from desk to desk searching for the fly I mentioned.

Next one seat number 5.

She looked very cute and I was about to have my fun even more.

Me: You are a fly!

In the next moment, she opened her arms and ran across the room making ZZZZZ noises and Frog girl chasing her.

Me: You are a Kangaroo! Look there red shark over there is after you!

Shark boy: Bro calm down! Why are you after me?! Hey calm down!

Next up Pikachu.

Me: Pikachu, there is a trainer that is about to catch you. Nope there are two.

With that he immediately began shooting electricity all around him.

I then went to seat number 12.

Me: I am a GHOST! NOW YOU SEE ME NOW YOU DON'T!

With that she began screaming "Ghost". Then I saw a guy with a tape quirk.

Ohh that's just perfect.

Me: Tape Candy Cane to the ceiling!

As I was about to jump to the next table, a dark creature blocked my way.

Me: The fuck?!

Dark Shadow: Kuro?! Is that you?!

Me: Dark Shadow?!

Dark Shadow: It's really you!!!

Me: Hey, long time no see!

Dark Shadow: I see you are as foxy as always.

Me: Well I am a fox after all!

???: Dark Shadow, whom are you talking to?

Me: So you are attached to that person now?

Dark Shadow: Yeah. His aura was calling towards me and I couldn't resist.

Me: I am happy for you man!

Dark Shadow: Say, how is it possible that you are here?

???: Dark Shadow are you okay?

Me: We found our Master!

Dark Shadow: You mean the Master of Darkness?

Me: Yep.

Dark Shadow: Where is he?

Me: Right there.

I then went back to Izuku's desk and sat on it very proudly.

Me: Let me introduce you to him! Dark Shadow, this is our Master Izuku Midoriya.

Dark Shadow: Nice to finally meet you Master.

Izuku: Huh?!

The look in Izuku's face was funny as heck. He looked soo confused what was going on. Well he didn't know Dark Shadow so it was kinda expecting.

Me: Oh wait before I forget.

I jumped to the Dandelions desk.

Me: You are a Pomeranian now behave like one and be nice to Izuku your owner!

Dandelion: Wuff.

Izuku: KURO!!!

Me: What, don't tell me you don't see the resemblance.

There was soo much going on in the class, it was ridiculous. The best part was that Aizawa was in the room watching everything and snickering at some things too.

Aizawa: Izuku, can you please get my class back to normal.

Me: NOOOOOO!!!!

Izuku: Can we enjoy this a little bit longer?

AIzawa: ... If you get them all down outside the training area, then I don't care.

Izuku: Kuro?

Me: On it!

Aizawa: Oh and make them all change into the sport uniform when you are on it. I will be waiting outside.

Me: YESSSS!

We then continued to watch the whole class for another 15 minutes. Hitoshi was one laugh-crying man on the ground while Izuku was also laughing but still sitting on his table. Dark Shadow was hovering all over Izuku and wanted to get some more attention. This made me very jealous.

Me: Go back to your owner Dark Shadow!

Dark Shadow: He is our Master!

Me: I don't care!

Bakugo was sitting on the ground acting as a dog and making some dog noises including whining for Izukus attention.
