Aka no Nitamame

In a matriarchal world where women dominate and men are treated as lesser beings, Kureto was cast aside at birth for the sin of being born male. He scraped by as an orphan, unwanted and powerless—until the day his unique skill awakened. A "supreme virility" skill that strengthens him with every act shared with a woman.

Under the guise of "training" with his dorm caretaker, Kureto masters his newfound power, achieving strength no man should possess. When he's accepted into the elite Knight Academy—a school meant for noble-born women—he sees a chance to change his fate. To become an honorable knight, to reclaim his dignity, Kureto will fight—both in the arena and between the sheets—against the very women who once looked down on him.

Touma Funasaka is offered an unusual recommendation for his next school by his homeroom teacher. The school in question is Toyashihara Academy—a national, full-boarding institution that accepts only students through recommendation, with no general admissions. It also happens to be his teacher’s alma mater.

The low tuition and full-boarding system seemed like the perfect opportunity, so Touma decides to enroll. But what awaited him was an academy that defied common sense—a place built atop a vast underground dungeon, ruled by sex and violence.

Though bewildered at first, Touma quickly adapts to the decadent academy life. While indulging in a corrupt and hedonistic youth, he also joins comrades to form a party and challenge the dungeon’s depths!

One day, the protagonist wakes up in the body of Charlotte, a gentle healer living in a world of magic and nobility. Her new life seems peaceful, until she discovers that Charlotte had just accepted a suspicious commission: to create a love potion.

The problem? Charlotte isn't a witch, just a misunderstood herbalist mistaken for one. And before she can figure out who requested the potion, the Crown Prince himself shows up at her door.

Convinced he's the mysterious client, Charlotte panics. If she refuses now, she might lose her head for disobedience! So she decides to fake it till she makes it, brewing potions by instinct and stumbling into one awkward royal encounter after another. But the more she tries to survive, the more tangled her fate becomes with his.

"Wait... isn't this one of those classic romance clichés?" 

Apparently, it's now her life.

"...Wolka?! Noooooo!! Y-you can't die on me!!"

Wolka, an adventurer, is a reincarnator from Japan. During a dungeon exploration, his party is ambushed by a powerful monster, and Wolka suffers fatal injuries while protecting his companions; in his final moments, he finally remembers the world he had reincarnated into was that of a dark fantasy manga he read in his previous life — that he and his companions were minor characters to be annihilated then and there.

But Wolka, empowered by his hatred for bad endings, desperately presses on for the sake of his companions — and defeats the monster. It only cost him an eye and a leg — but in exchange, he and his party escaped their intended fate. What he did not account for, however, was how the experience changed the young girls that were his companions.

"I swear I'll protect you this time!! So please, please, don't abandon me..!"

"I'll always be by your side... You're fine with that, right, senpai?"

"I would give my life for yours... That is what I decided."

This is the murky, otherworldly story of a reincarnated man who values happy endings above all and the girls who harbor intense feelings for him!
