"Alright, class. Today, we have a new student joining our class."

In Kunugigaoka High School, new students were not that rare. Still, most people would be curious at who they are. The teacher of this class was no exception.

She was a new teacher who fulfilled her lifelong dream just this year. The teacher was called Takashi Hayami. Takashi Hayami was a pure and naive person in a way. A type of teacher that annoys most people because they try way too hard.

Still, she was pretty popular with the class because of her looks. She probably never noticed how the boys stare at her ass every day with perverted eyes. However, none of the girls grew jealous of her because of Takashi Hayami's purity.

"Takashi-sensei, is it a cute girl this time?"

"No, Isogai-san, it's a boy."

"Eeeeeh!"

The boys grew disappointed at this. If it was a guy, it would just be someone popular that could hurt them or some loser, so they didn't care much anymore.

Takashi-sensei was still excited. Her naivety could be seen because she believed that the class must be perfect, with everybody being good friends and whatnot.

"Everyone, please welcome Dai Maou-san."

The excitement that was in the classroom toned down as the new student entered in. After all, the student called Dai Maou was the perfect example of normal, boring, and a loner. He was a boy with dark hair and glasses that covered his eyes. His expression was plain and he was of average height. He seemed to be mostly skinny as well. Dai Maou would be the type of new student that was considered a loser.

Takashi Hayami was thinking similarly, but as soon as she saw him, she put a goal in mind.

"I must make this child part of our family in this classroom."

Most would sigh at this pure and naive person.

The new student called Dai Maou was quickly forgotten after his arrival. At lunch, some tried to approach him as a show of kindness, but he did not say anything.

At the end of the school day, most of the students in his class ignored him. After all, their impression was of him was that he was a weirdo.

.......................................................................................................................................................................................................................

Dai Maou was a weirdo and he knew it. After all, he believed that he was the reincarnation of Satan, a demon lord from a world of magic called Estoria.

He knew it himself that he would be considered a weirdo. Heck, most would leave before he finished telling people his secret because it was unbelievable.

"Daisuke-san, can I have a croquette?"

Due to this, Dai Maou set out to pretending to be a human. Hence why the self-proclaimed reincarnated demon lord Satan is eating croquettes and walking home like a normal teenager.

"Hmm. The food from this world called Earth is delicious as always. It's definitely much better than the meat of a dragon. I shall add this to my Conquest Note for things I must limit to only myself when I become the dictator of this world."

Since he was reincarnated, Dai Maou a.k.a. Satan wanted to take over the world. Even though he knew he had no proof of him being Satan and it could be all a dream, that did not stop him from planning his conquest of the world.

"I wish magic could be used in this world, but none of my spells work. If I did have it, this world would have been mine."

Dai Maou sighed as he was thinking about magic. However, that did not deter him. Since he could not conquer the world through force, he was planning to do it what people from Earth called "authority".

"All I have to do is become the Prime Minister of Japan and declare war on the world. It shouldn't be that hard to conquer the world. After all, the ones who are smart gain authority. Once I become a CEO or something, I should easily do it. But I still need communication skills. I should probably interact with my classmates."

Unlike how he looks, the man once known as Satan was complicated. He knew how flawed, but he attempts to fix it because he realizes the benefit. He would even allow others to look down on him because he believes that in the end, he shall become the ruler of the world. At that time, Dai Maou would probably just torture those people nonstop.

As Dai Maou was walking in the crowded streets of Shibuya, he started to become excited. After all, he was a fan of manga and anime which most would call an otaku.

"I hope today, Doflamingo cuts Luffy into pieces. Or maybe Fairy Tail will be crushed. Hopefully, those Albareth dudes will know the right thing to do with the Fairy Tail chicks."

In this way, Dai Maou did not know he was a weirdo. After all, even otakus would look at him like he was crazy. But he was just greatly influenced by his previous life of evil. Heck, he even calls his house a mansion and his bike a steed.

As he was walking on the streets of Shibuya, he passed a girl. The girl was a top-class beauty. She had dark hair and alluring curves. Her face reminded him of an idol. Everybody around her was looking at all of the parts of her body, but she ignored them.

Dai Maou ignored her as well because he knew once he ruled the world, he could find better girls. But when she passed him, he felt something from her.

"Eh. Why does that girl remind me of something? From the looks of her, she's also my age. Is she another person who reincarnated. No! That can't be. It can't be that easy to reincarnate."

Just like that, Dai Maou ignored the girl. 

The girl, however, kept walking through the streets of Shibuya It looked like she was looking for something.

That day was a strange day for Shibuya. After all, many strange people arrived. Even otakus would think they were weird. It was not weird to cosplay in Shibuya, but the cosplayers acted very strange. Also, there were many beautiful girls at the prime of their youth there.

In a place that was just completely white, a winged person was floating. He had purple hair and a handsome face. The man was very short and seemed to be childish.

The man was playing chess against someone. However, that someone couldn't be seen. The pieces on the other side just moved by themself.

At that moment. someone appeared in that place. It was someone wearing a white robe, so their features could not be seen.

            However, this person also had wings.

"Lucifer, what have you done this time? Where have you placed the Holy Grail?"

The robed person seemed to be very angry, but their voice seemed to be one similar to a robot.

"Hey, Michael. I just did what God-chan told me to. I hid the Holy Grail."

The purple-haired boy called Lucifer responded with an uninterested tone.

"How dare you address Him that way? Besides, you hid it a place where anyone can get."

The robed person seemed to be worried that a catastrophe would happen.

"Hey, Michael. It's alright. Everytime someone makes a wish, it's usually something boring. I was just nearby a certain place and I wanted it to be interesting this time."

Lucifer seemed to be excited when he thought of this.

"But why in God's name would you disguise it as the latest copy of Weekly Shonen Jump?"
