異世界二度目のおっさん、どう考えても高校生勇者より強い

简介

Riku Takayanagi is a boring 32-year-old businessman with nothing special about him. Or so it seems. In truth, he once saved another world as a hero. Now he's back in Japan, living a normal life... until one day, he's dragged into the mess with three high school students and summoned again — this time to a different world!? Suddenly thrust into the unknown, Riku steadies the panicked teen heroes, encourages them, and teaches them how to survive. ___ **Character Designer:** [Okaya](https://mangadex.org/author/8913a2bb-9e14-4650-91eb-88372cf4742b)
