[Invincible + System + Regret + Multiple Heroines + Love Triangle]

In a world of high martial arts, one awakens a villain role system, enabling them to travel to other worlds, play the role of a villain, and extract the talent for playing a villain after completing missions.

...

Task 1: Play the role of the chief professor who killed the female lead's family, take in the female lead as his disciple and carefully train her, but ultimately be killed by the female lead when the truth is exposed.

"My beloved teacher saved me, but I killed him."

Task Two: Play the role of a simp who is unrequited love, fawning over the female lead and framing the male lead, only to be forcefully killed by the male lead in the end.

"Only when you lose something do you realize how precious it is. It turns out that my senior brother is to me what water is to a fish."

Mission Three: Play the role of a remnant of the Sin Clan who infiltrated the academy with the intention of breaking the Sin Seal to release the Demon Sword, but is executed after his identity is exposed.

"It's all our fault. If only we had trusted him a little more... He's not the sinner, we are."

Task Four: Play the role of a powerful hegemon in the Spring and Autumn and Warring States periods, who waged wars to conquer other states, only to die at the hands of his concubines.

"He was a tyrant, but also a wise ruler, and we destroyed this peaceful and prosperous world with our own hands."

Mission Five: Play the role of the mastermind behind an evil organization, relentlessly pursued by the protagonist group, and ultimately sacrificed for his great cause.

"God and demon, good and evil, I can no longer tell the difference..."

...

Behind every mission lies the truth of the world.

Unaware of the truth, Luo Chuan returns to the world of high martial arts with his villainous talents.

The heroines who remained in their original worlds couldn't help but shed tears of regret upon learning the truth.

My name is Fujiwara Seiji, a transmigrator. What I love most isn't saving the world, but admiring the helpless yet beautiful sight of those arrogant heroines falling into the abyss. When the black-stockinged upperclassman, Kasumigaoka Utaha, took off her stockings in front of me for three million yen in surgery fees. When the blonde loser, Eriri, knelt down begging me to invest in her dreams. When the icy beauty, Yukinoshita, walked into my room to rebel against her family. Only then did I realize how interesting this world truly is. Hero? Savior? No, I just want to be a… behind-the-scenes mastermind who controls the heroines. [Friendly Reminder: The protagonist of this book is loyal to his own desires; those with a saintly heart should avoid this!]

[Anime Crossover] + [Chat Group] + [Multiple Female Characters] + [Invincible Path]

He traveled through a broken world and became the captain of the Hyperion, an unsinkable ship in an eternal cycle of reincarnation.

One day, after saving and anchoring countless world bubbles, I received an invitation from the Multiverse Chat Group.

Yingmei: "Damn it, is this how the main character is treated?"

Kiana: "The captain's strength is quite formidable!"

Esdeath: "He looks like an ordinary person, yet he has such exaggerated strength. There are truly many powerful beings in the myriad worlds."

Asuna: "Although I'm just an ordinary person, fortunately, my game data can be transferred to another world."

The myriad realms, a brand new stage, truly something to look forward to!

Seimei woke up to find himself transported to a world of anime and manga. Good news: he was also bound to a system essential for any transmigrator. Bad news: this world wasn't just infested with evil spirits and monsters, but also with various urban legends, like the Slit-Mouthed Woman, Sadako, Kayako, and Hanako in the Toilet… However, thankfully, after binding with the system, Seimei became a legendary Onmyoji. He not only possessed powerful abilities but could also summon various shikigami to fight for him! His goal was to become the strongest Onmyoji and, at the same time, build a grand empire! …Yotsuya Miko: I only feel safe when I'm by Seimei-sensei's side. Ebina Nana: Seimei-sensei, please don't do this here… um… Kasumigaoka Utaha: Hmm~ Seimei-kun, do you prefer white or black? Nakiri Erina: Now it's my turn to taste you. Kirigaya Suguha, Asuna, Shinomiya Kaguya, Fujiwara Chika, Eriri, Suoh Yuki…

What would it be like to awaken a different superpower every week?

Kiyoshi Minazuki is reborn into a crossover anime world. Hoshino Ai is not only his childhood friend, but also the aloof and unattainable Yukinoshita at his school. Other characters include the genius writer Kasumigaoka Utaha, the rare blonde beauty Eriri, and the transfer student from abroad, Ellie, among others.

News about Mai Sakurajima, who debuted as a child star and is currently semi-retired, can still be found online.

At the same time, he gained a system that allowed him to awaken his superpowers once a week.

Dream manipulation, teleportation, telekinesis, and more...

All sorts of strange and imaginative abilities appeared one after another.

Furthermore, the art style can change instantly depending on how the user interacts with it; there are indescribable controls, such as pausing and perspective...

Just as Kiyoshi Minazuki was considering how to remake a "Stop Series" film and was preparing to finalize the casting of the important female characters,

Looking at the girls around him, he belatedly realized something.

That is...maybe...he didn't need to pause time or make a choice at all?

Because the girls are too enthusiastic.

Due to an accident, Ye Ran was drawn into an extremely cruel cycle game.

Fortunately, the Sinful Enslavement System was awakened at the start, allowing the player to obtain various rewards by enslaving anime beauties.

Since then, while the reincarnators around me were still struggling and complaining about their own survival.

However, he embarked on a unique path of hunting beauties to become stronger!

You have successfully enslaved Kasumigaoka Utaha and received the reward "Eye of God".

You forcibly enslaved Enoshima Junko and received the reward "Geass".

You have successfully won Esdeath's submission, opening the Sinful Treasure Chest and receiving a Freeze-Freeze Fruit as a reward.

Zombie 100%, Demon Slayer, Dark Gathering, Fallout 4, Type-Moon, Honkai Impact...

As Ye Ran continued to hunt down beauties and grow stronger, one anime goddess after another joined his team.

Years later, when he stood atop countless multiverses, he was shocked to discover that he had long since left everyone far behind.

Waking up, he found himself transmigrated into the body of Hachiman, the self-destruction master. Looking at his lifeless eyes in the mirror, he secretly made a vow. He would make all those who had mocked him involuntarily say, "Look, that person seems like a social butterfly." Until one day... "Tell me, which one do you choose?!" Looking at the girls surrounding him, each holding various weapons, a bead of cold sweat trickled down Hachiman's forehead.

Yuu Kamishiro has traversed numerous anime worlds for over twenty years. After his wife's death, he became a widow's husband. His suppressed female nature, suppressed for over a decade, awakens, and he even joins a chat group of wives, gaining the ability to travel between different worlds. Yuuki Kyoko: You saved Asuna, so I have no choice but to repay you with my body! Sawamura Sayuri: If Eriri doesn't like you, is my kimono tempting enough? Eri Kisaki: My rationality has failed me, just give yourself to me! Mouri Ran: Me too! I'm so hot! Mrs. Takayanagi: Yuu-kun, I have no choice but to repay you with my body. Busujima Saeko: Please call me Kamishiro Saeko, Yuu-kun smells so good! After experiencing countless worlds, with countless beauties standing behind him, Yuu Kamishiro has become a god!

Sun Baihe time and again traveled through time, searching for his way home. He had once teamed up with Asuna in Sword Art Online, their combined swordsmanship reaching the top of Aincrad; he had also used his 3D Maneuver Gear to slice through the nape of a giant's neck in the world of Attack on Titan; he had studied magic at the Clock Tower, only to be unexpectedly swept into a time warp, returning thousands of years to teach Artoria how to govern; he had shared drinks with Whitebeard, and later single-handedly conquered Mary Geoise, the holy land of the Celestial Dragons, ending their rule; he had debated swordsmanship with Retsu Unohana, experienced Sosuke Aizen's Kyoka Suigetsu, and dominated the world of Bleach, seemingly undefeated; he had even been slammed in the face by the White Tyrant, and became friends with her… After countless hardships, he returned to the main world, exhausted both physically and mentally, becoming a lazy bum who only wanted to rest for a few hundred years. But unexpectedly, the sixth wave of spiritual energy revival opened countless dimensional portals. Seeing familiar faces on the television screen, Sun Baihe shuddered. "Damn it, the debt collectors are here!"

[Characters appearing include characters from Honkai Impact 3rd, Star Iron, Grand Blue, Oregairu, Kaguya-sama: Love Is War, and Saekano... as well as some heroines whose origins are unclear. I won't cite their sources; those who like these series will understand.]
