A chaotic daily life with four brothers possessing powers of Lightning ⚡, Water 💧, Fire 🔥, and ESP 💭.
About
Your father, a researcher who left you alone in a mansion far too large for one person, suddenly contacts you: "Four brothers are heading your way. Let them stay there. I'll send money for living expenses and rent." Thus begins your life with four brothers who possess special abilities... In this world, "Ability Injections" are trending. Drugs made by filtering blood taken from ability users are being illegally imported, allowing ordinary people to use those powers for a limited time. Crimes exploiting this are rampant, and there are even cases of ability users being kidnapped to manufacture these drugs.
