Harry Potter and the Dovahkiin - Chapter 13: Journey 2

Yi Zaha. The crazy demon crazy for martial arts. While he was running away after stealing the heavenly pearl of the Demon Cult Leader, he fell off a cliff. After thinking that everything was over, he opened his eyes to see that he had returned back to when he was a waiter… And he is being beat up for something that he didn’t do. The crazy demon who returned to the beginning of his days as a waiter! Will he go crazy again, or will he drive his enemies crazy?

There’s the so called class transfer.

Among the high school students that were given cheat abilities, Kirishima Ran was given 『Underling Training』for some reason, a skill that can make a woman a slave.

Ran who was driven out by the kingdom using an absurd reason will make use of the given skill freely to take revenge on his classmates, release his desires (This is mainly the reason), and fight off the world’s system.

It’s a story of him using his wonderful skill making his classmates turn to an obedient cute and lewd slave.

The year was 2026, and the world wasn't what it used to be. Ever since the Abyss Gates cracked open three years ago, spilling monsters and dungeons across the planet, life had turned into a chaotic mess. Cities were half-ruined, half-rebuilt, and people clung to whatever normalcy they could find. Hunters—those brave or crazy enough to fight the monsters—became the new heroes. Everyone else? Well, they just tried to survive.Fin wasn't a Hunter. He wasn't a hero either.He was just… Fin. A lanky 19-year-old with messy brown hair, a chipped front tooth from a dumb skateboard accident, and a power that everyone called useless. Absorption. Sounds cool, right? Like he could suck up energy or steal someone's strength. Nope. All it did was let him “feel” things he touched a little more than normal. He could tell you the exact texture of a brick wall or how warm a coffee mug was—big whoop. No fireballs, no super strength, no flashy moves. Just a glorified touchy-feely trick.“Fin, you gonna eat that sandwich or just stare at it like it's gonna confess its life story?” Meg's voice snapped him out of his thoughts.He blinked and looked across the rickety table at his best friend. Meg was short, loud, and had a wild mop of dyed purple hair that she swore made her look “intimidating.” It didn't.
