And Now He Trains Beautiful Warriors Using Superpowers!?

I, who should have died after being hit by a car, was born again in another world.

However, I was born in a shady minor family that used magic and controlled wooden puppets called the Marren Clan.

Possessing a strong interest in magic since my previous life, I spend my time zealously studying magic to the point where even the people in the vicinity draw back.

One day, I heard I was to be married to my little sister when I turned 16 in accordance with the traditions of the Marren Clan and decided to flee to the city.

For now, since I have the strongest magic, I guess I should idle around making only enough money so that I don’t have to work for my whole life.

"I did it again...!"

The Hero who can't seem to set out on his journey!!

The protagonist, who was reincarnated into another world, becomes a hero and receives the task of defeating the Demon King. To repay the world that accepted him , he decides to set out on a journey... However, he can't seem to leave the first village, as he is constantly tempted by charming heroines such as the female priestess, his childhood friend who is a magician, and so on!

Thus, the birth of the "I did it again...!" type hero!

Long ago, a powerful demon lord ruled over the people until an equally powerful hero rose up to defeat him. To counter future threats, Rosewood Academy, a school for heroes-in-training, was created. Today, Rosewood Academy enrolls only the best of the best, and Arnest Flaming is the best of them all. The top student in the school, a dutiful girl nicknamed "Empress of Flame", she has an irritating encounter with a light-hearted boy in the school hallway one day who seems to equal her powers, though she's never seen him before. He introduces himself only as Blade, and Arnest soon finds out not only is he transferring into the school as a new student, but she is personally requested by the King to help him settle into daily life in Rosewood Academy.

There’s a legendary Bishoujo Game that has become popular among Japanese gentlemen.

Its name is “ Magical★Explorer” or Magiero for short.

The game’s protagonist has a cheat-like power with12 different beautiful heroines to flirt with, including additional 12 heroines from the DLC, a harem of 24 beauties. I have become that protagonist!………………Not. Instead, I have become the third-wheel character who always laughing like an idiot next to him.

Of course I was in despair at first.

Of course. If I am the protagonist I could have all 24 heroines for myself along with unparalleled cheat power. However, since I am the third-wheel there’s no heroine that would lay their eyes on me.

But now I couldn’t care less about the protagonist and his heroines. Why? Because I discovered magic. While I was using it, I have become interested in it. I want to master it. I want to become the strongest. Thus I have decided.

I would abandon half my role as a protagonist’s friend to train my magic and then I would beat the hell out of that cheat who can solo the Demon King.

Depicting the story of a shut-in, Kirihara Yukito, after being reincarnated into another world.
His peaceful life with his precious caring sister, Sana, suddenly come to an end when a beast appeared and attack them, thus reincarnating him into the “Ever World”. Moreover, knowing that Sana also got reincarnated into the Ever World, for the sake of finding his beloved little sister he begins his journey in another world…

Franz is a recent graduate of magic school who is having trouble finding a job — he constantly bungles interviews due to his poor communication skills. With all the major magical jobs out of his reach, there’s only one place left for him to go.

The industry of black magic. Known for being Disgusting, Dirty, and Dangerous, Franz is incredibly hesitant to actually enter such a market until he no longer has a choice. With his back to the wall, he talks to the Black Magic Incorporation’s CEO, who tells him the truth — black magic has shed its harmful exterior, and has instead become Pure, Pleasant, and Permissive. In short, Black Magic Inc. has actually become a white company.

Join Franz, his Cerberus boss, and his succubus familiar as they get to work in a company which actually respects them as human beings, which is probably another cry for help from Japan’s overworked populace in that a legitimately caring company is seen as a fantasy, but you probably already tuned out after I said “succubus familiar”.

A man who had always been fascinated by magic, even at the age of 30, suddenly died and woke up in a different world. He was named Shion and hoped to find that magic existed in this new world, but soon discovered that it did not.

Feeling depressed and purposeless, he eventually stumbled upon the existence of magical power after a certain incident.

“I have an idea. If there’s no magic, then I’ll just have to create it myself,” he thought.

With that determination, he began to study magic every day. Through encounters with enemies that could only be defeated with magic and a widespread disease that could only be cured with magic, he became a hero who saved the world. This was the story of a simple magic enthusiast who was thrown around by fate but overcame it all with the power of magic and an unyielding fighting spirit. He eventually spread the use of magic to the people.
