As Sukuna in Invincible - Chapter 41: Complicated

That afternoon, Roland received the most absurd gift imaginable—his stepmom handed him a System literally.That’s right. Not a game console. Not money. A real, cheat-like System... the kind usually reserved for transmigrators and chosen ones.Except Roland had transmigrated eighteen years ago, and nothing remotely “chosen” had ever happened since—until now.The catch? It wasn’t just any System. It was the “Mother's Little Tasks” System, formerly owned by his doting (mysterious) mother. And its first mission?[Mission: Go on a blind date.][Target Options: Yukino Yukio (Mom), Yukino Haruno (Elder Sister), Yukino Yuki (Younger Sister).][Warning: Once locked, your chosen girl can never marry anyone else.][Reward: 1000 Points, one self-selected supernatural ability from Mall]Roland: “...What kind of twisted matchmaking app did I just inherit?”After reading the mission, Roland was stunned. An arranged romance at 18 was already bad—but a binding rule that prevented the chosen girl from marrying anyone else? What if he failed the mission? Would she be alone forever?“And this is supposed to be a System?”“Mom! What the hell is this mission?” Roland asked, his face darkening.“It finally triggered! All those Points I spent transferring the System weren’t wasted,” his mother replied cheerfully, ignoring his outrage.“You set this up? Why?”“You’re nearly an adult and you’ve never even dated. Of course I’m worried.”“I’m only eighteen! I have college entrance exams next year!”“Exams don’t matter. But youth without love isn’t youth at all.”“...Is that something a mother should say?” Roland muttered. Most mothers pushed their kids to study harder—his acted like grades were irrelevant.“What kind of mom does this to her own son? And why is Aunt Yukio even on the target list? That’s just insane!”“Well~, I don’t know what kind of girl you like. The Yukino family has all three types—mother, elder sister, and younger sister—so I gave you options.”

I was just your average burnout. Now I’m a kobold in a dungeon where everything wants to eat me—and frankly, I get it. I look delicious.Reincarnated as the weakest possible monster in the worst possible place, I start with nothing but panic, backward knees, and a skill called Civilization Mimicry—which is sealed. Because of course it is.But survival isn't the story.This is the story of what comes after.Of finding meaning in the scraps. Of building law from ashes. Of kindling memory in a place designed to erase.Because even if the world sees kobolds as nothing, I’ve seen what we used to be.And I’m going to bring it back.Firelight by firelight. Burial by burial. One fragile tradition at a time.Because if the world wants kobolds to be nothing?Then I’ll teach it what nothing becomes when it learns to dream.

Kael was a “rat”—a lowly stable boy in a frozen, brutal medieval world where Knights ruled with iron and Barbarians crushed skulls with bone clubs. His life was worth less than the manure he shoveled. That changed the night he butchered a Knight with a rusty dagger to pay a debt of blood.Chosen by the God of Slaughter, Kael awakens the Aether System. His cheat? The ability to project his soul into other worlds, live countless lives, and bring their powers back to reality—if he survives.But power is not free. It is bought with pain, time, and sanity.World 1: The Wild West. He spends a lifetime as “El Lobo,” a legendary gunslinger. He returns with the muscle memory of a master marksman and a 12-gauge shotgun. World 2: The Martial Arts Realm. He trains for decades as a Wuxia disciple. He returns with internal energy that can shatter steel.Now, as the Kingdom faces war and monsters surge from the dark, the nobles sneer at the servant boy holding a strange metal tube. They chant spells. They draw enchanted swords. Kael takes a slow breath. He racks the slide. Click-clack. “Parry this.”

In a world teeming with Titans, Colossals, Gigantic Monsters and Kaiju's, Erian who reincarnated makes his living collecting scraps of low-grade Defective Genetic Serum, realised he transmigrated along with his system.
