The Obsessive Villain Makes Me Go All Out [Quick Transmigration]

To achieve a certain goal, Caesar deceives a System and becomes its Host, letting it take him through one world after another.

To complete his missions, he has to play roles like these:

A stepping stone for a Dragon-Proud Protagonist, a fish in the pond of a White Lotus playboy, the devoted second male lead pursuing a submissive, a suicidal cannon fodder in a supernatural world, a side character infatuated with the heartthrob in an infinite-flow world...

Caesar: ?

Allow me to refuse.

Besides that, Caesar looks at his lover, who transmigrates with him and always manages to get roles as an obsessive yandere or a villain:

"Life is hard enough already. Could you please stop adding twists and turns to our missions?"

His partner, who can turn into a white crow (enthusiastically): You don't like it? Then how about we try something else?

Planned Worlds:

[Western Fantasy Dragon-Proud Protagonist] So This Is the Dragon-Proud Protagonist? That's It? (Completed)

The protagonist's path to godhood has been abruptly cut short! No need to thank me, I did it.

Red-robed cardinal x demon lord

[Apocalypse Rebirth] Passing Through the Entire World of a Drama Queen (Completed)

Declining all roles related to "The Drama Queen Beauty Refuses to Be Cannon Fodder in the Apocalypse (Reborn)."

Esper x merperson/mutant (the submissive is ostensibly a clone)

[Modern Beastmen] Listen, Who's Knocking at the Door (Completed)

Is there more to the story of the submissive and the scumbag seme? Does scumbag romance suddenly turn into a legal education show?

Black snake detective x white crow villain

[Interstellar ABO] Are We Really Reversing History Here? (Completed)

At least pheromones are a good thing.

Unfortunate rebel prisoner x prison warden

[Supernatural Livestream] Chasing My Dream in the Supernatural World, Good and Evil Always Get Their Due (Completed)

Turns out, if you don't go looking for death, you won't die.

Supernatural streamer x thousand-year-old vengeful ghost

[Infinite Flow: Clearing Stages with Looks] I Don't Belong in This World.jpg

The heartthrob is the scariest thing in an infinite-flow world. I'm sure of it.

Player x BOSS

[Preorder: The Trash Player Gets Pulled into a Game]:

In the post-apocalyptic era, the few humans left have split into two camps: the [Old Era League of Legends], whose members focus on mutations powered by astral energy, and the [New Humanity Coalition], which specializes in consciousness transfer and mechanical augmentation.

Xie Qi, a squad leader in a League of Legends combat unit, suffers from a memory-loss debuff. Fortunately, he's also bound to a "game" connected to reality.

Unlike the game's protagonist, he isn't some righteous do-gooder.

He's a scumbag who swindles enemy factions, steals pocket money from his own organization to fund his little team, teases his teammates like cats when there's nothing to do, and uses them like cards when trouble strikes.

After falling in love at first sight with an enemy loyalist with red and white heterochromia, he spends every day wondering how he can get him to defect.

As it happens, the enemy loyalist he's set his sights on is thinking the same thing.

Years later:

Some scumbag: You should've defected to my side sooner. Just thinking about all the wonderful time we wasted for no reason breaks my heart, Ying-chan~

Some loyalist: Is that so? You made me fail my mission the very first time we met. What a novel way to win me over, Captain.

PS:

1. The seme really is a trash player. Seriously, he raises his teammates like cats and treats them like cards.

2. At first, the seme and uke belong to opposing factions. They're enemies, and they really do fight each other. Only later, after breaking away from their factions and teaming up, do they stop fighting.

A post-apocalyptic world with a touch of cosmic horror, plus a game: espers versus mechanical ascension.

Theme: As long as life goes on, keep striving.
