Louise: "Only I would tolerate your hentai lolicon behavior, you demon king, so you must always love me~"

Stella: "I am the princess of the Kingdom of Familion. It is my good fortune to meet you on the path of seeking higher goals and becoming stronger to protect my country. And it is even more fortunate that you are also a dragon."

Aiko: "The heavy responsibility of continuing the royal bloodline of the Holy Dragon of Avalon now falls on our shoulders. You better take responsibility!"

Emilia: "I am your queen, you are my husband, my dragon god."

Alicia: "Hi~ It's great to see you again. This time we'll definitely be happy together, right?"

Kiana: "I will never let go of your hand, because you are my other half!"

......

......

Kurima: "I only wanted to take on a talented disciple so I could show off to my acquaintances, but why did she end up becoming my husband?"

(Multiple female protagonists) (Three Devil Fruits, close to the original work) (No system) (Adult-oriented) (Dark style) Columbian Sakai was originally a working-class slave in modern society. When he transmigrated to the world of One Piece, his fate took a turn. He encountered the Dark-Dark Fruit, which was known as the most evil, and from then on, his destiny began to resonate.

He couldn't help but sigh: This is fate!

(Breaks up couple pairings, no system, not an overpowered protagonist) "Spirit particle manipulation combined with blood armor can create skeletons and human-shaped arms? Isn't that Susanoo?" "The ability to jump to distant spaces in an instant, isn't that Amenotejikara?" "The flames of the spirit particles, once touched, will endlessly burn everything, I know! This is Amaterasu!" "But I'm Ishida Uryu!" Ishida Uryu originally thought he could just be an observer watching a deaf boy save the world, but he changed his mind. "Now that I'm here, and have mastered this power, then there are some things I must change!"... Aizen

Hiroki, who transmigrated into the body of a nobleman's son-in-law in the Seireitei, initially thought he was destined for a life of ease and comfort in a wealthy family, until his wedding night when he was forced to "receive" over two hundred Uchiha refugees from the Naruto world.

Transmigrating to the Type-Moon world, Ryougi Shinobu becomes a magician. He initially thought his life would consist of fighting the Holy Grail Wars and occasionally saving humanity, but he gains access to a dimensional forum linking different worlds. Shinobu asks, "Can humans and demons really get along?" Ryougi replies, "Immortal demons are perfect experimental subjects, ideal for mining or working in nuclear-contaminated areas. Isn't that harmonious enough?" Ai Haibara asks, "I work for a cult, and they killed my sister. How can I get revenge?" Ryougi replies, "Take that drug that turns people into children, and I'll immediately scatter their ashes."... Members from different worlds constantly appear on the forum. While helping them solve their problems, Ryougi also collects some local specialties and earns a few hundred million points.

When Su Yu transmigrates to the Naruto world and becomes Fugaku Uchiha, the head of the Uchiha clan who is about to be wiped out, he awakens a god-level choice system.

Sorry, but this time, I, Uchiha Fugaku, will not give up easily!

The story begins with the filial son, Uchiha Itachi, realizing his mistakes and repenting, leading him to kill Shimura Danzo and restore the name of the Uchiha clan...

This Konoha will never be the same again!

A 21st-century otaku accidentally transmigrates to the world of Naruto, becoming a cannon fodder ninja who gains the most experience points from being killed by powerful figures. He has no bloodline limit, no good eyes, no family background, and even the typical transmigrator's cheat ability is just a useless piece of junk. There's no other way but to play it safe and develop his character cautiously in the early stages…

His soul traveled through time, and he discovered that he had arrived in an unknown Spider-Man parallel universe and was reborn in Peter Parker's body.

Time travel isn't the problem, rebirth isn't the problem, but the problem is I've been reborn into Peter Parker's body, so why am I not Spider-Man?!

Fortunately, when merging with the original owner's soul, it was discovered that this body actually contained the memories of a third soul, and the name of this third soul was Tony Stark.

Having been given a second chance at life, since I missed the opportunity for the poor to rely on mutation, I can only strive to become a self-made millionaire and survive in this world through the power of technology.

"I want to reach the top step by step, I want to be Iron Man!"

Transmigrated Cang, possessing a flint-wielding left eye that awakens a magical world, uncovers a cosmic truth with his cousin, Shenxue: Earth is actually a prison for alien gravediggers, and Shenxue's family bloodline is a container for a spiritual virus. The two break through seven cycles of reincarnation, discovering that the world is actually a fairytale manuscript from a higher realm. Ultimately, they tear apart the shackles of narrative, wielding the silver-haired flint-wielding pen to rewrite the laws, transforming bronze doors into bookshelves, and the gravediggers into footnotes to the fairytale.

In the world of "The Irregular at Magic High School," I was bound to a villain simulator.

[Mission 1: Publicly humiliate Shiba Tatsuya, instilling murderous intent in Shiba Miyuki towards you. Reward: S-rank magic - Gravity Collapse!]

[Mission Two: Eliminate Mayumi Nanakusa during the Nine Schools Battle. Reward: God-tier CAD - Eternal Heart!]

As a result, I became a scoundrel, a villain, and a demon in everyone's eyes!

But they didn't know that when Yokohama was engulfed in flames, I transformed into "Nameless," suppressing the entire scene with a single Gravity Collapse attack. When the Great Asia Alliance invaded, I transformed into "Phantom," protecting all of Japan with my Eternal Heart.

The female protagonists, while gritting their teeth and vowing to kill me, are also searching the world for their savior, hoping to repay him with their bodies.

Until that day, my vest accidentally fell off.

Looking at the petrified female protagonists, I shrugged: "Surprised? That's right, the Demon King you hate the most and the hero you love the most are both me."
