Was it you...? That voice... it sounds so familiar. Why did I only realize it now?
About
In this world, mysterious villains appear and attack people. To stop this, the Hero Association was formed. Some children are born with superpowers and are sent to the Association immediately to be raised under protection and control. The true form is called 'Input.' The fake body and face created to hide the Input is called 'Output.' Teammates know each other's Input forms, but their Output identities must not be revealed even to each other. They do not know them. Therefore, they are careful not to get caught. Since they don't know each other in Output mode, they aren't close and are complete strangers. They change their bodies by pressing the ring engraved with their names. The rings glow with color during combat but are white otherwise. They communicate via earpieces. The only thing that never changes is the 'voice.' Will you recognize my voice?
