Bowing slightly to show respect, (YN) looked at his fellow classmates with a small smile on his face. “Hello everyone, I am (FLN), (YN). I will be in your care.” He introduced himself.

The classroom erupted in cheers from the female students, they were already fangirling over (YN) as soon he stepped foot in the classroom. He almost already has what all the female students want from a boy. Tall, handsome, deep yet gentle voice, broad shoulders, and a great smile that shows his row of perfect white teeth. And thanks to Slaanesh, (YN) has undeniable unspoken rizz and even almost all of the male students weren't safe as well.

The teacher managed to make the students settle down before speaking. “Well class, Mr. (FLN) here came from Europe, specifically the nation of the United Kingdom.” The teacher explained.

A female student immediately raised her hand as she stood up. “Are you half British?” She asked curiously.

Shaking his head, (YN) would just begged the Chaos Gods to torture his soul than being British. “No, my parents are japanese.” He said.

“Well then, Mr. (FLN), how about you sit next to Hyoudou, Issei in the back row.” The teacher said.

The female students protested against the idea since the boy named Issei was infamous for being a massive pervert along with his two friends, the female students told the teacher their concerns of (YN) getting corrupted by Issei and his two friends’ lewd acts.

The teacher made the class quiet by raising her voice, (YN) excused himself as he walked to the back row where he saw a spiky brown haired boy which was Issei. Putting his bag on the hook at the side of the desk, (YN) sits down on the chair. Issei leaned on him.

“I'm Issei, the future harem king, nice to meet you.” He said, extending his hand out for a handshake.

(YN) shook his hand with an awkward chuckle. “Umm… I'm (YN), the future king of England.” He said, jokingly.

“Alright, let's get class started, our topic is why skibidi toilet Goated?” The teacher said.

[Timeskip]

(YN) ate his lunch by himself at some secluded area because the cafeteria and the classroom are not safe because of the female students, he was deep in thought while listening to music. (YN) has knowledge of sacred gears, they are artifacts created during the Great War that let the user possess different abilities from physical to magical abilities, after he shook hands with Issei, he felt a sealed sacred gear with a soul of a dragon, the Red Dragon of Domination.

Aside from that, (YN) feels the presence of devils on school grounds. The student council were devils, however, there was another group of devils in the school so (YN) will get someone to investigate it along with keeping an eye on the student council as well. (YN) continued to eat his lunch until in the corners of his eye, he saw a figure standing on the rooftop not so far from the school.

Using magic to enhance his eyesight, he saw a tall woman with jet-black hair, wearing a skimpy revealing outfit with the similar colour of her hair, and a pair of wings. Her presence was almost nonexistent, but (YN) can still sense it if it was small as an atom.

‘A fallen angel?’ He thought, staring at the woman.

“Commander.” A robotic-like voice said out of nowhere.

(YN) doesn't need to look at the 7 foot tall space marine behind him, the marine was part of the Raven Guard chapter, one of the best stealthy chapters and despite being clad in heavy power armour, they still managed to be as stealthy as possible.

“See that woman?” (YN) pointed. “Follow her and gather information, I took an interest in her.” He said, returning back to his lunch.

The marine, without making any noise, vanished in thin air and leaving no evidence behind.
