Please defeat your dead-last classmate, Uzumaki Naruto.]“System, do you know what year it is now?”[Year 60 of Konoha]“Right now, it's Year 2 of Konoha! Is there something wrong with this system?!”...Many years later, Gensou opened his eyes again, standing on the rooftop of the Chunin Exams building. Looking at the Third Hokage, who was ready for battle, he smirked slightly:“Although it's a few decades early, I finally made it.”[Raw: 火影：我都硬刚五影了，系统才来]

A suffering MC novel—the main character must be forced to suffer, be oppressed until they’re hovering between life and death, dying and living here and there. They can have a golden finger, but before getting it they must pay the price. They can also have beautiful women, but all are snake and scorpion beauties, able to look at but not eat.

“Curse” is just that type of suffering MC novel. The main character Xi Wei, after being forced to experience numerous sufferings, had, at last, become the most powerful, at the same time linking together with the world’s qi and fate. After he was oppressed too miserably, he committed suicide and buried the entire world with him.

Zeno transmigrated, in the end arriving at “Curse”.

Zeno was adopted by the MC, finally becoming the number one person/wife.

Zeno: Help, I don’t want to be destined to be raised by this perverse person!

All living things (wipe away tears): You must rescue this world, ah.

Xi Wei: Come over here.

- Description from Novelupdates

She was the Eldest Legitimate Daughter of the General's Mansion, treacherously harmed and died a miserable death. Perhaps moved by pity, heaven granted her rebirth. She returned to four years earlier, not only possessing heterochromia that allowed her to see what others couldn't but also equipped with a portable space. She vowed to make those who hurt her and her mother pay in this life.He was a Prince with a Different Surname from Moli Country, holding military power and commanding awe in all directions. It was said that he had conquered most of Moli Country, and even The Emperor showed him deference. Legend had it he was a bloodthirsty prince who killed without blinking an eye.One day, she encountered a ragged but handsome man on the street, who chased after her, shouting, “My wife, my wife.”The woman said, “Damn it, who is your wife? Aunt isn’t even engaged yet! Go where it’s cool and stay there.”The man responded, “You are my wife, and I've decided to follow you for life.”“A feel-good story, both leads are strong, a pampering love story with 1v1 romance.”

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.
