World Teacher: Special Agent in Another World

Sirius was the best secret agent the world had ever seen, but his last mission resulted in a grim outcome. After he was killed in action in an effort to save his comrades, he ended up being reborn in a strange new world—literally!

The only regret from his previous life was that he didn't get to see his students grow up. So, with the knowledge and experience he'd gained from his previous life, Sirius sets out anew to travel this bizarre world.

Along the way, he'll change the lives of those he meets. To some, he's a beloved teacher; to others, he's a strong role model... or even a crush!

"If you have nothing to lose, then come with me. I'll teach you how to live again."

The man once known as the strongest secret agent will now travel the world with his students! His journey has only just begun.
