Supervillain Idol System: My Sidekick Is A Yandere - Chapter 420: It Doesn’t Always Pay To Be Loyal (Part 3)

One day, spatial tunnels opened in the very fabric of reality, connecting Earth to a planet that came to be known as Xavier, a planet that has a lot of deserted settlements belonging to the civilization that lived on this planet before we started exploring it.

Each settlement not only hides a secret of its own but also treasures, knowledge, and unthinkable technologies.

In this new world, magicians rule the world and make the rules.

They are those who can contain magic energy, an energy source present in Xavier, in their bodies.

This energy is used to mainly empower supernatural cells.

One can get them by consuming evolution materials.

These supernatural cells suck magic energy to manifest one's superpower in the real world.

Elliot, once the son of magicians in the channel opening stage, now lives the life of an orphaned and poor boy.

Elliot is the weakest magician to ever exist in the world, a world where the strong are respected and the weak are disdained.

With the death of his parents, the ones who used to look down on his has no reason to control their feeling.

With a dim fate ahead of him, he grits his teeth and silently moves on to the day the light of glory shines on him, setting him apart from others in a single day, letting him taste what it means to be God!

Her step-sister just died three months ago. Now, she insists on marrying Chu Lui, who is supposed to be her future brother-in-law, the mind behind the Chu Enterprise. The world is sure that she, the new bride-to-be, had caused her step-sister’s death in order to seduce him.

Even her own mother says to her cruelly, “Don’t call me ‘Mom’. I don’t have a daughter as vicious as you.”

Kai’s life was small—coffee-stained mornings, cracked recipes, and a system in his head that tweaked toasters and dough like it was nothing. Then the sky shattered. Aliens—Skraiths, jagged and brutal—invaded, tearing his city apart with green-glowing weapons and relentless claws. Superhumans rose to fight back, fire and lightning blazing through the chaos, but Kai’s world crumbled with them.Hiding in his apartment, Kai stumbles on blood—human and alien, smeared on his wall after a superhuman battle. His system, once just a tinker’s tool, awakens, offering him a choice: mimic their powers, temporary and wild, through the blood itself. Desperate, he takes it—stealing pyrokinesis, then electrokinesis, then kinetic energy, each power burning through him, fading fast. But it’s not enough. Armed with a humming Skraith weapon and a body tougher from alien blood, Kai joins a ragtag crew of enhanced fighters—Liv, Rylan, Jace, and Tucker—scraping to survive in a warzone where every shadow hides death.As Skraiths swarm and the city burns, Kai’s system pushes him deeper, analyzing, integrating, crafting minor enhancements—durability, strength, sparks of power that could make him a target or a savior. Government factions, rogue scientists, and the aliens themselves start sniffing around, drawn to his strange tech and blood-stolen abilities. By the time Kai crafts his first super-powered enhancement—an artificial strength boost—he’s no longer just a tinkerer. He’s on the edge of something bigger, something dangerous, where blood and sparks could forge a hero—or break him entirely.In a world unraveling, Kai’s fight for survival becomes a desperate race to master his system, outrun the Skraiths, and confront the truth: the power he’s chasing might destroy him—or remake the world.

This hilarious fantasy story mixes mythological figures, cosmic entities, and a wolf babysitter with just too much contracts on his hands.It revolves around a Monstrous—though, gullible—wolf, reduced to a babysitter and a magnet for bad contracts.Ruben—formerly Ravenswood—is a classic “grumpy but good-hearted” reluctant hero. He is powerful and fearsome, but his terrible decision-making and misfortune always puts him in some kind of inconvenient pact.He got captured by a Human, who later tricked him into a lifelong contract of protecting his daughter, Alicia—whose identity is shrouded in mystery—who also turned out to be a psychotic Yandere!In an attempt to flee the suddenly-catastrophic Gihon—which is earth—with the Human’s daughter, Ruben was obstructed by Pluto, who also tricked him into an absurd pact to slay THE Cthulhu, as the ticket to let him through the other world.Ruben urgently sought to escape Gihon, so he unwisely agreed, only to recall who the all-powerful Cthulhu was. It was too late, though.Successfully crossing worlds to Pison—another type of earth—our Fenrir was met with the “Queen of the coast,” also known as Leviathan—a severe pervert.She attacked and defeated him, but when he woke up, she had apparently made a Master-servant pact with him, in his sleep.As they traveled seeking human cities in Pison, our misfortunate wolfie encountered a godman; Jobina, the daughter of Job, the second of the seven mortal powers.Jobina—a masochist with a vendetta against Leviathan, and a tendency to turn everything into a competition—attacked him for being associated with the evil Leviathan, only to be soundly defeated.Shocked by reality, Jobina protested that she also wanted a pact with Ruben, so he’ll coach her to be powerful. And when the time is right, she’ll slay Leviathan!Our easy-to-fool protagonist, and his terrible life choices, agreed, recruiting yet another troublemaker he’d have to babysit.He only wants an easy going life without problems and crisis!The story has a larger plot, where Ruben—and his babies—constantly, “accidentally,” ruin Sarvest—the antagonist—plans.Sarvest is used to dealing with gods and cosmic entities, not an unworthy—yet effective—opponent in a bubbling wolf-turned-human.Ruben later meets what we would call God—a dumb teenager who only cares about entertainment—who also duped Ruben, using his kind-heartedness, into some kind of horrible pact.“The Silent Pact of a Wolf Babysitter” is a story filled with laughs, chaos, and unexpected twists. It follows Ruben’s misadventures as he navigates a world of cosmic powers, absurd pacts, and the challenges of babysitting a group of eccentric and overpowered individuals. With a larger plot involving Satanas’s grand schemes and Ruben’s accidental heroism, this tale promises both humor and a compelling narrative.
