Y/n's costume:

All Might: "It's time for the trial of battle!!! I'm liking everyone's styles! Very cool!! Y/n, you might wanna change yours a bit you never know what perverts are around!"

Mineta goes to look at them closer causing them to kick him away.

Y/n shrugs.

Y/n: "I can handle it." This is the last time I have Daki, Mahito, Doma, Sukuna, and Istaroth work together to make a costume for my female version, actually, any version if I let them design my male version it'd probably be worse.

Tenya: "Sesnei! Regarding the performance ground we'll be using, is it the mock-city from the entrance exam."

Izuku: Ah, so it's Iida in there! He's looking pretty cool in that, too...!!

All Might: "You'll see---in fact, take two steps and you'll be there! This will be an indoor battle trial! Villain cleanup is usually seen out in the open, but statistically, the better part of it is an indoor job. Most acts of villainy are committed indoors. Imprisonment... house arrest... the black market... in this hero-saturated society. Hehe. Why, any villain with intelligence is lurking in the shadows!! For this test, you'll separate into "Villain" and "Hero" groups. For a two-on-two team battle!!"

Class: "!?"

Shoto: I want to fight Y/n, maybe I can get answers.

Y/n: I wanted to do a 1 v 2. It'd be easier for me to test my skills.

Tsuyu: "What about the foundational  training?"

All Might: "This is foundational training! Only this time there won't be any robots it'd be okay to just destroy!"

Momo: "So how do we determine who wins and loses?"

Bakugo: "Is it okay if we just blow them away?"

Ochaco: "Is there a threat of expulsion like with Aizawa Sensei's exercise...?"

Tenya: "If we're separating into different groups, what would be the best way to do so?"

Aoyama: "Doesn't this cape look killer on me...?"

All Might: "Hnnn~~~ I can't hear you speak all at once!!"

As All Might talks Y/n raises their hand.

All Might: "Yes, Y/n?"

Y/n: "There's an odd number of students, can I fight by myself?"

All Might: "Hmmm." They're strong enough to take all of them by herself. Keigo and Aizawa have fought them before. It'd be too dangerous for these rookies to fight them. 

As All Might contemplates whispers are heard. Students start drawing lots.

Team A: Ochaco and Izuku

Team B: Shoto and Mezo

Team C: Momo and Mineta

Team D: Tenya and Bakugo

Team E: Mina and Aoyama

Team F: Koji and Rikido

Team G: Jiro and Denki

H: Fumikage and Tsuyu

I: Mashijiro and Toru

J: Kirishima and Hanta

K: Y/n

All Might: "After some debate I'll be fighting Y/n-"

Shoto & Izuku: "What?!"

Bakugo: "Damn right, they will!"

Y/n: "Awe, thanks Katsuki-Chan. Although I would prefer to fight multiple people at once."

All Might: "And the first two pairs to do combat will be the following. Team A are the heroes. Team B are the Villains."

Y/n doesn't pay attention to the fight before them as they notice Shoto walking towards them.

Y/n: "Sho?"

Shoto: "A word."

Shoto grabs their wrist.

Y/n: "Release me."

Shoto: "I want answers."

Y/n: "You won't get them."

Y/n snatches their arm back.

All Might appears behind them.

All Might: "Todorkis. Is everything okay?"

Y/n: "Peachy."

Shoto: "No! I want answers."

All Might: "Fine."

Y/n: "Huh?!"

All Might: "You want answers. Y/n is a villain. You and three other classmates will start the fight and 30 minutes in I'll appear as back-up. This fight will be an hour long."

Y/n: "If I win?"

All Might: "Shoto has to drop the subject."

Y/n and Shoto shake hands.

All Might collects the students.

All Might: "The best in this match was young Idia!!!"

Idia: "Wha-huh!!?"

Tsuyu: "But weren't the winners Ochako and Midoryia?"

All Might: "I wonder why I could possibly think so~~? WHO KNOWS WHY?!!!"

Momo raises her hand.

Momo: "Yes, All Might-Sensei. It's because Iida was the one who adapted the most to the situation."

As Momo drones on Y/n looks at Shoto who is staring at them.

Y/n: "Well done Katsuki-Chan."

Kaatsuki: "Thanks, Y/n-San."

Shoto looks over at his classmates.

Shoto: I wonder who All Might will pick.

Y/n and Shoto watch each fight looking over at each one.

All Might: "Good work everyone. Now for the final fight. Y/n will be the villain. Shoto, Bakugo, Yaoyorozu, and-"

Keigo walks through the door.

Keigo: "Yo." 

Y/n: Keigo Takami aka Hawks... "Ready?"

All Might: "Wait. Why is Hawks here? Why are you here?"

Hawks: "Y/n wanted to even out the fight."

All Might nods while sweatdroping.

All Might: "Jiro will start the fight and 30 minutes in Hawks and I will appear as back-up. This fight will be an hour long. Instead of you not being able to hear anything like the previous fights you'll be able to hear everything."

The said students stare at each other.

Y/n summons a petite young woman with long, dark brown hair, parted in the center and worn braided back into a large, low bun, which is held in place by a floral tama-kanzashi hairpin. She has large, gentle eyes that initially do not possess pupils, only a haze of lavender that fades to dark purple the higher it goes, and notably red lips in contrast to her pale complexion. She is noted to have an attractive appearance by others. She is wearing a dark purple medium-lengthed hōmongi kimono that is decorated with wavy pale purple tree branches and red flowers, and a cream-colored taiko musubi obi to secure it around her waist, as well as plain white socks and violet zōri sandals.

Y/n: "Tamayo, I have a favor to ask."

Tamayo: "Anything, Y/n-San."

Y/n: "I'll head out first."

Y/n prepared first they used their obi to dig under the building and hide the fake weapon beneath the building. Then they stand in the original room waiting for them. The students were watching as the girl stood there.

Y/n looks to the left.

Y/n: *Whispering* "Mahito?"

Mahito: "What? I got bored."

The students watch as Tamayo turns to her mirror. Y/n enters.

Tamayo: "Hmm? Did you forget something?"

Y/n: "That's right. I need to devour you before I forget... since tonight's your last night here. Right, Tamayo?"

Tamayo: "Ah...!"

Y/n's obi sashes wrap around Tamayo. 

~In the viewing room~

The students stare at them.

All Might: "There's a hostage situation that's insinuating cannibalism. Also, Y/n's hair is black for some reason."

~With the group~

Kyoka: "Hostage?!"

Bakugo: "What is that damn extra plotting?"

Momo: "Y/n isn't going to actually eat the hostage, right?"

Bakugo: "Of course not idiot! It's all an act! Icy-Hot, you're helping me find them. You two extras find the missile!"

The group splits up trying to find their objectives.

Shoto enters the original building. Unknown to him Y/n's obis reach behind him.

Shoto: "Huh?"

He turns around only to be taken by the obis Y/n sent.

Bakugo opens a sliding door.

Bakugo: "Miss! Ah...!"

Y/n stands inside, holding Tamayo in their obi sashes.

Y/n: "Are you a hero? So you came. How many of you are there? I know one is that white and red-haired, ugly little brat. Is there a Pro with you? Or will they be here soon? I know you're not a Pro. You seem weak, after all. I have no use for anyone who's not a Pro. Got that?"

~Veiwing room~

Keigo: "5 minutes have passed. Where even are those three?"

All Might: "It seems that Y/n used the cameras to their advantage."

~Back with Bakugo~

Bakugo: Her body... What's going on? I don't see the woman's body. She's not bleeding.

Y/n: "I never devour dirty old people or anyone ugly."

Bakugo: "Ah!" Y/n's eyes! They read Upper... Six? "Let that person go!"

Bakugo get's ready to attack.

Y/n: "Who do you think you're talking to?!"

Bakugo: "Grr...!"

Y/n attacks Bakugo with their obi sashes. Bakugo is launched back into a building before he can even move.

Bakugo: She's so fast... I never saw that coming! Upper Rank... Does that rank have something to do with her strength? I have no strength in my limbs. My body's numb! Calm down!

Bakugo adjusts his gear.

Bakugo: My body's responding fine. Otherwise, I wouldn't be alive right now!

Bakugo gets up.

Bakugo: I have no strength in my limbs... because I'm afraid! I'm afraid of that damned extra! Is it because she managed to attack me so fast even though she's quirkless? Is it because of those pacts? My body's numb because I hit my back hard, so no wonder! Their weapon is their belt. It has supernatural abilities. They can absorb humans inside it! Could it absorb anything? That's why no matter how hard we searched inside the building, I couldn't find a secret path that a human could fit through! All they need to abduct humans is a crack big enough for that belt! No wonder we couldn't find the weapon they either had it in that belt or somewhere else.

Y/n: "Oh, you're still alive? Oh? You're not as fragile as I thought. I do like your eyes. They're lovely. I'll just gouge out your eyeballs and devour them."

Y/n licks their lips.

~The Viewing room~

Ochaco: "She just launched him across the road into another building!"

Tenya: "She's playing the part of Villain excellently."

Denki: "Where did All Might and Hawks go?"

Tenya: "They went down to get ready to head in."

Ojiro: "10 minutes past."

~With Y/n~

Bakugo: "Ah!" 

Y/n: "Fufufufu..."

Bakugo launches himself forward. Y/n does the same.

Bakugo: "Ngh! Ugh!"

Bakugo blasts through Y/n's obi sashes.

Y/n: "Fufu!"

Y/n's obi sashes bind together and go toward Bakugo. Bakugo blocks it with his explosion and is pushed into the air.

Bakugo: "Ugh... Gah! Urgh... Ugh!"

Bakugo blasts through Y/n's obi sashes again.

Y/n: "Ngh!"

Bakugo: "Grr..."

Y/n hits Bakugo's left gauntlet, and Bakugo is hit to the ground. He lands beside Y/n's sash where Tamayo lies dormant.

~ADVERTISMENT~

~Meanwhile in Kimitsu No Yabia~

A young man of short stature and average build with pale skin and lavender-purple eyes. He has short hair that is neatly styled and vertically shaded from a dull and light green to black. He wears a button-up collared shirt under an all-white iromuji-haori and dark blue Seigo-Sendeihira styled hakama pants.

He's walking around a house.

Male: "Lady Tamayo?"

The male calls out.

Male: "Lady Tamayo?!"

The male calls out more worried. After a few more calls the male is frantically running around looking for said woman.
