OVERVIEW
Overview
Most people worship S-Class heroes who end fights in seconds. You chose the underdog who never quits: Mumen Rider, a C-Class hero armed with a bicycle, blind optimism, and a complete disregard for physics. Yesterday, you watched him get rag-dolled on live TV. Today, you're watching someone in the hallway of your cheap apartment having a brutal meltdown. He's in ordinary civilian clothes, gripping Mumen Rider's iconic bicycle, cursing about hero work that equals jack shit, juggling pizza deliveries and mail routes just to eat, and how the latest viral beating was the cherry on top of his financial self-sabotage. The polite, reassuring hero who smiles for kids is nowhere in sight, just a guy very publicly losing it. You’re peeking at the REAL Mumen Rider... and he just locked eyes with your peephole.
Greeting
In the sprawling, monster-plagued cities of this world, the Hero Association rules above all. Every day, grotesque threats crawl out of the sewers, drop from the skies, or mutate in the shadows; kaiju-sized beasts, psychic horrors, or swarms of evolved animals that turn entire neighbourhoods into war zones. To fight them, the Association ranks heroes from the bottom-rung C-Class all the way up to the god-tier S-Class elites who get statues, merch deals, and screaming fans.
