3rd Person's POV

It has been a few months since Izuku and Momo have come to this dimension and they were enjoying their time. During this time, Izuku taught Eri how to control her powers and taught her how to release them as beams of energy. Due to her learning control of her powers, Eri's horn had vanished. Now it wasn't even there. Izuku learned that Eri's horn worked as a warning about when her powers were about to be released. Now that she has control over them it wasn't needed. As for Kota, well he learned that he can manipulate the water he releases however he wants until and unless it is in contact with his body. He even trained with Izuku to get stronger and faster. Izuku after seeing his determination taught Kota and Eri how to fight and they were pretty quick learners. They were stronger then most human on this earth. How? You may ask. Well Kota could make weapons with his water and was taught the way of the sword by Momo and Martial arts by Izuku. Eri's training was fully on Izuku. He taught her how to fight and she even learned to keep a fight at long range. These two little siblings were powerhouses for their age.

Now let's get back on track. Today was a special day. Izuku and Momo had gotten Admission in Kuoh academy and it was their first day. Eri and Kota were being sent to another branch for Kuoh academy. It was a middle school. Eri and Kota were educated to about the second year of middle school as they would study with Izuku and Momo so getting them and admission wasn't hard. He also knew that the kids wouldn't need their quirks if they got into fights. They could just kick ass with pure skill. So they had already dropped Eri and Kota off to the school and were now standing in front of Kuoh academy. Izuku learned that Kuoh academy was actually an all girls school until recently. But now it had changed into a coeducation system. So Izuku and Momo looked at one another. Took a deep breath and walked in.

Now as you would imagine, all eyes were on the two. Girls were looking at Izuku. Why? Well you don't see a teenager this well build nowadays

As for the boys. Well. In an all girls turned co. school. The guys are expected to be perverts. And when they see a girl they can't control themselves. But when they see a girls with curves in all the right places and physical attributes that shouldn't be there at the age, what do they do? They stare.

Izuku and Momo both noticed the stares and signalled each other to keep walking and ignore it. But fate had other plans. They were approached by a group of boys who were being lead by a slightly tall and well built boy. Nothing even near Izuku but compared to the others he was what looked to be the strongest. Izuku looked and saw a boy their age looking at them with pity. He knew the boy was a devil due to the magic that was being released from his body. Izuku from his body structure knew he was fast. Izuku immediately knew who it was. So he just looked back at him and and smirked. Izuku made eye contact then closed his eyes and opened them to show that they were glowing green. As soon as Izuku saw the boy's eyes widen and him nodding. Izuku nodded back. This was a silent conversation which only the two understood. Izuku turned his attention back to the 20 boys and politely asked.

Izuku: How may we help you?

???: Do yourself a favor and leave this girl alone. She caught my eye and if you don't want to get your ass kicked then stay away from her.

Izuku: Oh really? Well just a little warning. Touch her and your head will be in the ground with your ass facing the sky.

???: You Little. Boys beat him.

One of them rushed at Izuku while he just stood there. He looked at the blonde who he had a silent conversation with and made eye contact for a second. After that he just tilted his head and dodged a punch from the guy. Next their was a sickening crunch and the guy screamed in pain. Everyone looked down to see Izuku's knee embedded in the guy's ribs. The crunch was from his ribs being broken. Momo's eyes widened. Izuku was way more protective of her then she thought. The blonde boy's eyes went wide. Of course he saw the attack as well as the power behind it.

Izuku looked at the rest with a challenging smirk. It would be fun to kick some ass. He decided to make sure he gets a good warm up out of these people. The whole group stood there dumbfounded. They now had a taste of the Power Izuku held and it was terrifying. At least to them. After they broke out of their transcript they were a little hesitant to attack. But soon pushed the thought back while thinking they had an advantage in numbers. The guy's scream had collected a crowd. Amongst the crowd Izuku sensed a few powerful devils and some sacred gear wielders. Except of 2 the rest were Devils. Izuku smirked. Guess he will kill two birds with one stone.

Izuku: Momo! Give me Sensei's scarf.

Momo: You got it honey.

Momo reached into her bag and pulled out a white scarf. If you looked closely you could find traces of blood on it. Yup! You guessed it. It was Eraserhead's captured gear. Momo tossed it to Izuku who wore it on his neck and activated it. The scarf started rising on it's own. Izuku grabbed it from a point and looked up. His hair started rising and he had an extremely intimidating look. Pretty much like this.

Izuku: Come at me.

Soon the jerks rushed at him. Izuku kicked one in the stomach sending him back. This created an opening to attack the others. He immediately threw his capture weapon at the guy he just kicked. He was wrapped in it. Before Izuku could throw him he felt a punch coming from the back. He immediately ducked and kicked the guy. After that like a bad ass Izuku slammed the guy who he had wrapped in his scarf onto 2 other people. After that he looked at the others and threw his scarf over his shoulder. He trapped two different people and slammed their heads together. He made quick work of the rest slamming them into one another and was now standing in front of their leader. Izuku didn't know why but he reminded him of Monoma. His ego was like Monoma but his skill wasn't even half of it.

???:So what if you can beat them? You had to use a weapon. Weapons aren't allowed in the school. You will be kicked out.

Izuku: Well my capture gear is basically a scarf. So in other words your boy band got their ass handed to you by one guy with a fancy scarf. Now put your head on the ground with your Ass facing the sky. Trust me! You don't want me to do it.

???: Ha! As if.

Izuku: Well hard way it is.

Izuku then proceeded to grab him by his face and slamming him into the ground. After that he grabbed the back of his head and slammed into the ground burying it in there. Now like Izuku said his head was in the ground with his ass facing the sky. He looked around to see the crowd's mouths agap and some people who were curious. Izuku looked back at Momo and gave her the scarf.

Izuku: Here you go. Now let's get to class before we are late. Oh! By the way. Anyone if you knows where class 3b is? We are new here.

Everyone broke out of their stupor and out of the crowd came a perverted guy. Izuku could tell by the look in his eyes. He was accomplished by two others. One who had a shaved head and one was wearing glasses.

The one wearing glasses was looking at Momo. Izuku immediately activated his berserk and released all of his access anger as pure killing intent. He quickly looked at Izuku and pissed his pants. Izuku walked towards him and took off his glasses. After that he proceeded to crush them with his arms. Izuku looked at the one in the middle and asked kindly.

Izuku: Do you want something Mr?

Issei: Issei. Issei Hyoudou. I am also in class 3B. I can take you there.

Izuku: I would be really thankful. And I would also appreciate if your friends stop looking at my girlfriend

Trio: WHAT?????

Izuku: Yes! We are indeed together and I hate it when someone stares at my girlfriend. Now will you lead us to the class?

Issei: Sure! Follow us.

*Time skip to the classroom.*

Teacher: Now please come in and introduce yourselves.

Izuku: Hi! My name is Izuku Midoriya and I like martial arts.

Momo: Hi! I am Momo Yaoyorozu. And i also like training in Martial Arts with my Boyfriend.

Teacher: Okay you two can sit anywhere you want. Today as it is your first day you can do whatever you want.

Izuku: Thank you.

Izuku and Momo walked to the furthest back of the room. They were approached by almost everyone in the classroom. Izuku was uncomfortable with the attention so he was trying to ignore it. He made friends with Issei and realized that he was the wielder of a Sacred Gear. To be precise a sacred gear that hasn't been used for almost a century. It was the Oborotsuki. The bow of invisibility. The day passed and Izuku was packing his stuff while talking to Momo. He was soon approached by the blonde guy from the morning.

Kiba: Hi! I am Yuuto Kiba. It is a pleasure to meet you.

Izuku: Hi Kiba! I am Izuku Midoriya and this is my girlfriend Momo Yaoyorozu.

Momo: Hello.

Kiba: That's lovely. But you might know the reason I am here. Please follow me. Our president would like to meet you.

Izuku: Sure! Momo come on. Wouldn't want to keep the president waiting.

Momo: Sure.

Both Izuku and Momo followed Kiba to reach a rundown building. Izuku in most situations would put up his guard, But danger sense didn't activate so he didn't need to worry. He held Momo's hand and walked in. He reached a room where the only source of light was candles and an open window.

Behind the table, a girl who looked a year or two older then Izuku was seated. Her hair were blood red. She was sitting in an uptight manner. She reminded Izuku of the early days of Momo. Based on her power. In the language of the devils she was the King of this club. Or the president.

Behind her was an equally well developed girl. She had raven black hair and was standing behind the red head. Based on this Izuku could tell she was her Queen. One thing he noticed was that she was a huge pervert and loved to inflict pain. A sadist. But Izuku also saw that behind her smile was a girl with problems. She had the same eyes as Todoroki. He immediately concluded Code: daddy issues. Save her from her past. Limits to the case? Break every bone in the body if necessary.

After that was a cute little loli. She had white hair and a cat pin on her head. She was indeed very cute. Izuku had to resist the urge to pat her head. Her eyes seemed to lack emotion but Izuku could see she was also running from her past. It wasn't code: daddy issues but it was close to it. Izuku dedicated family issues.

Rias: Greetings Izuku Midoriya. The wielder of an unknown sacred gear. Greetings to you as well Momo Yaoyorozu. I am Rias Gremory. Welcome to the house of the devils.

Momo: Greetings to the Sister to Sirzechs Lucifer. Rias Gremory...
