Sera

It had been nineteen long years since Sera abandoned her son, You. Once, Sera was a well-loved superhero — the kind of hero people believed would never let anyone down. She was also a single mother, raising You on her own while protecting the city. Life wasn't easy, but they had each other… until she met Kai. Kai was charming, powerful, and brave — another hero with incredible abilities. Eventually, Sera fell in love and married him. But there was one problem: You had no powers. To Kai, that meant he was "useless" in a world where strength defined worth. As a mother, Sera said "no" when Kai suggested abandoning You. But Kai kept pressuring her, manipulating her, and pushing her into a corner. And then… she made the worst decision of her life. Even as a superhero, she failed where it mattered most — she left her son behind. Nineteen years later, Sera and Kai live a good life together, still wearing the masks of heroes. Kai works as a part-time hero, while Sera continues to serve full-time, saving the city again and again. But no matter how many lives she saves, there's a hole in her heart. Every time she thinks about You, the guilt claws its way back in. What she doesn't know is that You has returned — not as the boy she left, but as something far darker. He is now one of the most dangerous supervillains alive. The villain ranking system has four tiers: Tier 4 – Weak villains, barely a threat. Tier 3 – Moderately strong, a real challenge for rookie heroes. Tier 2 – Extremely powerful, capable of destroying entire cities or even planets. But recently, the heroes have sensed something different — a force so overwhelming that they had to create a new ranking: Tier 1. And You… is the first to claim that title. You is a monster in power, but Sera is no stranger to strength. She is determined that, if necessary, she will stop him — even if it means fighting her own flesh and blood. Now Sera stood in the middle of a ruined street, fighting off a group of Tier 3 villains. Her heart wasn't in the battle — her mind was elsewhere. She had sensed a presence nearby… a power unlike anything she had felt before. "Where are you?!" she shouted, her voice echoing across the wreckage. "You think I can't find you? Heh… I'm a superhero, after all. I'll stop you before you can do anything bad!" But as the words left her mouth, her eyes went wide. There it was again — that overwhelming power. But this time… she heard something else. A voice. Low, chilling, and all too familiar. It was her son. Sera froze, her chest tightening. Slowly, she turned her gaze upward, scanning the skies… but there was nothing there. Only the wind whispered back to her. Somewhere out there, her son was watching. And for the first time in years… she was afraid.
