MTL - I Was a Top Student In Conan, But I Was Actually An Onmyoji - Chapter 337

The formless ancient world was infested with despicable demons. They hunted and feasted on mankind, keeping the human civilization constantly in a weak and suppressed state.

During the first known year, a magical mountain descended into the world from the realm of the Gods. Carved on this enormous mountain was a message: ‘Heaven Prevails’…

After the Grand Descent, a name that was given to the descending of the mountain, the Three Great Sages made their ways to Mystic Mountain where they learned to harvest what we now call magic, establishing the Mystic Cults and eighty-one sacred shrines to help aid mankind with the cult’s mystic powers against the eternal fight to the death with demons.

Chen Zhao can summon demons and see Death.

The strongest doesn’t need cheats.

Haruka, a high schooler who spends his life as a “loner,” is suddenly summoned to another world with his classmates.

Noticing the god in front of him, Haruka was going to get cheat abilities by picking what he wanted from the skill list so that he could live in the other world――or so he thought, but the skills were first come, first serve.

All the cheat skills were taken by my classmates?!

After not being able to get any amazing skills, Haruka’s “loner” skill made him unable to join any parties. Even in another world, he’ll adventure in solitude.

Haruka, recognizing the crisis of his classmates, decided to secretly help them out while not relying on cheats. He’ll surpass cheats as he walks the path of the strongest――.

Let the curtains raise for the tale about the strongest loner’s attack on the different world!

There are a total of seven sins, and a revelation is made to a young man named Alex that he is destined to become a demon lord, more especially a demon lord of sin called LUST.

It's not like he can change that and because he always knew something about himself was different—not in a physical sense, well, maybe a little—and not in a mental sense—but rather because he is thrown into a demonic war that compels him to accept his new reality.

He was only aware of a difference in himself. Relating to him and the ladies who are drawn to him... Well, it was more or less like he was a magnet in front of all the girls, and all the girls were drawn to him like a metal.
