Nakahara Kasane was a third-year university student who felt trapped in his dull, uninspiring life… in other words, just another mob character in the vast world.

However, after getting caught in a sudden accident and losing his life, he woke up to find himself reincarnated into the world of The World’s Strongest Archmage Reincarnates into Modern Fantasy and Becomes Invincible—a light novel he had devoured back in middle school!

He thought his days of mediocrity were finally over, and a dazzling fantasy life awaited him. But the reality of his reincarnation was—

「Whaaaaaaaaaat the hellllllllllllllllllllll!? Who the hell is this guy!?!?!?!?」

A mob character!?

No exceptional talents. No connections to the main characters of the novel. If things stayed like this, he was doomed to repeat his previous life’s insignificance!

Yet, even in the face of such a hopeless second life as a mob, Kasane refused to give up.

Haunted by regrets from a life that ended in mediocrity, he swore that this time, no matter what, he would carve out a future where he could truly shine!
