MTL - I Just Wanted To Retire and I Was Forced To Become a General - ~ Side Story・The marriage under the sunset is my lost youth

The NPC sets out on a journey to defeat the Demon Lord, joined by beautiful girls he meets along the way.---This is an NSFW story, so if you're under 18, turn back now, son. No NTR, and no full-on Yuri. There might be slight Yuri—like girls kissing and stuff during threesomes—but it's not that kind of Yuri where the girls fall in love with each other while in a relationship with the MC.---

An ineffable rebirth, taking advantage of a mystical magic cube that was produced from rebirthing to pass through various worlds(anime, novel, movie, games, etc), collecting whatever I want to obtain!

“Infinite Abilities Academy”On his first day at Infinite Abilities Academy, Class F freshman Su Bei awakened a new ability. It was only then that he realized their world was actually a manga. And the protagonist of this manga was his classmate Jiang Tianming.But that’s not the main point. The main point is that in the next chapter of the manga, he, Su Bei, is destined to die tragically in the restroom! This event would kick off the protagonist’s first challenge at the ability academy.Su Bei: …The only good news is that this chapter of the manga hasn’t been published yet. He can alter the course of the story and save himself from a cannon fodder’s fate through his actions.As everyone knows, becoming friends with the protagonist doesn’t guarantee escape from plot-induced death, but becoming the protagonist’s enemy will certainly result in defeat at the protagonist’s hands.Under the blazing sunlight, the golden-haired boy smiled recklessly, yet there was a hint of solemnity in his purple eyes: “Saluting you on behalf of fate, the unluckiest of the unlucky in this generation~”

One day, billions of young and middle-aged people around the world were pulled into an underground palace survival game.
