Global Reincarnation: Only I Know the Plot - Chapter 7:

The Third World War has been ended by the efforts of Kamijou Touma. With that, he vanished. With the Magic Side regrouping, the Sabbath for their followers has arrived.

In the headquarters of the Science Side, Academy City’s strongest Level 5 Esper Accelerator has washed his hands off the “Darkness.” Along with Last Order and Misaka Worst, his days pass by peacefully with no sign of GROUP.

Hamazura Shiage has formed a new ITEM with Kinuhata, Takitsubo and Mugino. Peace has come to the hands of the alumni who have “graduated” from Academy’s Dark Side at last… at least until a new evil “first year student” appears before them.

— This is a follow up to the popular Toaru Majutsu no Index light novel series, where Kamachi-Sensei has promised to deliver new premises and give a totally new flavor to the fights and plot developments

On the desolate barren planet of Rennes, an Asian teenager named Lin Yuan receives an admission notice for the Empire’s best military academy San Romia. So begins his life changing military school career.

Min's system, System #151044, is tired of watching him get girls and make dumb decisions yet still manage to defeat the villain. If only he was the villain, there's no way Min would win.

His wish was granted. He now upgraded from a bodyless helper system to the evil villain, Ronin Dreadborne!

-----------------------------

After getting murdered and reincarnating as a system inside a Hero Transmigrating Machine, System #151044 spent thousands of years wondering why he had such a cruel fate to be a system for incompetent transmigrators like this.

But the worst is Min Cheng............

Because Min Cheng spends all his Hero points on girls instead of leveling up! And he is the dumbest transmigrators he ever met!

But through a rogue system that gave them a code to free themselves from their roles as a system, System #151044 was able to transform into Min Cheng's enemy on the next world, Ronin Dreadborne, in a mage fantasy world!

[Fate itself is evil. The only true enemy is fate, and I have defeated it.]

[And I shall teach you how to defeat it too. I will be giving you the gift of freedom. ]

[Be the master of your fate like you were always meant to be. And conquer those who try to stand in your way.]

That is exactly what he did as Ronin, and to defeat an evil fate, you have to be evil yourself!

“I will be the best villain in all the dimensions! Watch out, Min Cheng! I'm coming for you!”

How pitiful is a life without love?

In every happy ending, there is always a male character who either meets his demise or lives the rest of his life alone.

Maybe these male characters regard feelings as playthings, or maybe they just don’t care. But what if they each meet someone who is willing to love them and spend the rest of their life with them?

These are the love stories of said male characters and their counterparts.

NOTE:

Although the author labeled this as a quick transmigration novel, it is far from one. Each arc can be read as a short standalone story.
