The Speedrun Manual of Miss Witch - Chapter 252

The Red Dragon came from the vast wild wastes, coveting all the strength in the world. It once had countless titles: Mountain's Wrathful Flame, Infernal Calamity, Crimson Emperor, Ashen Dragon......The world trembled under the shadow of the giant dragons. He stirred up the craze of the magic industrial revolution; in the empire he established, Wyverns roared, artillery fired in unison, and steel beasts appeared in the sky and on the land, while disasters from another world rampaged everywhere.“Submit, or die.”Cassius spread his wings, blotting out the sun, and gazed down at the trembling humans, elves, and dwarves below, saying thus.......It is a story about a Red Dragon with a player template conquering, ruling, and transforming an alternate world.(Pseudo of DnD, The Fourth Calamity, Red Dragon)

Ren Arakawa thought getting stabbed by his psycho ex-girlfriend was the worst way to die, and it would end his story. Turns out, it was just the prologue. He wakes up in a parallel earth full of dungeons, monsters, hunters and way too many women with clingy tendencies and knives.To make things worse, the goddess who reincarnated him? Yeah—she's the Yandere Goddess, the divine creator of obsessive love and the world he is going to reincarnate is female-dominated world, and she’s mad Ren called his ex “crazy.” So she curses him:“Every girl who likes you will become yandere. Like, explosively, murderously, loyalty-soaked yandere, to them you will be their oxygen. Good luck, idiot~ Go ahead and realise how amazing this yandere love is.”BUT—plot twist—the God of Creation, who’s been hiding in a broom closet in heaven since the beginning of the universe to escape his yandere stalker (guess who?), snatches Ren’s soul mid-reincarnation and gives him a cheat skill:[Heartsteal] – Absorb one power from any yandere girl who's obsessed with you.“My guy...you should help me...this bitch is driving me crazy..”Now Ren just wants to survive dungeons and not die from accidental love. Instead, he’s collecting powers:A healer who murders teammates because they looked at him wrongA pop idol who sends her fans to the shadow realm for shipping her with someone else other than RenA plant mage who grows garden clones of him to cuddle and possibly do other thingsArmed with sarcasm, trauma, and increasingly dangerous girlfriends, Ren must climb the power ladder, level up, and eventually punch a literal goddess in the face to break the curse and destroy the concept of Yandere and be a free man.Love? Nope. Power through emotionally unstable women? Absolutely.

A tree of 10,000 flowers, the world is the door.
The spells change a lot, but the hearts of the people are unchanged.

Xu Yiren, who has 300,000 fans, scolded Song Tianmei, a new traffic flower with more than 5 million fans, on Weibo: “Who in China doesn’t know that Gu Yu is your backstage!” People are sitting at home, and the pot is coming from the sky.

Gu Yu: “Excuse me?”

Three months later, Gu Yu put his hand on Xu Yiren’s side and said softly, “I have never been the backstage of anyone in my life, but from today onwards, I will be your backstage.”
