CONCEPT vs CONCEPT
Okayu was never the type to worry too much about anything. With his carefree laughs and easygoing nature, no one expected him to be the one to leave everything behind — and step into another world.
In this strange land, power doesn’t come from ordinary magic but from concepts: abstract forces that shape reality itself. Okayu receives the Concept of Evolution, granting him the ability to grow and surpass any limit… if he has the courage to keep moving forward. But he isn’t alone: his best friend wields the same concept, turning friendship into rivalry.
To make matters worse, the classmate who always despised him is brought along as well — bearing the terrifying Concept of Rejection. In a hostile world filled with fragile alliances and clashing hearts, Okayu must prove whether evolution can truly overcome rejection.
An isekai of intense battles, tangled relationships, and choices that change destinies. After all… evolving means more than just becoming stronger.
