Takayanagi Riku is a 32-year-old office worker living an ordinary life in Japan — or so it seems. What no one knows is that he once saved a fantasy world as a legendary hero. After completing his mission, he returned to Japan and settled into a quiet corporate routine, leaving his otherworldly adventures behind. However, his peaceful life takes an unexpected turn when he is suddenly summoned to another world once again — this time alongside three confused high school students chosen as new heroes. Though shocked by this sudden isekai summoning, Riku quickly regains his composure. Drawing on his past experience as a former hero, he steps into the role of mentor, guiding the inexperienced teenage heroes and teaching them essential survival skills for navigating a dangerous fantasy world. As chaos unfolds, Riku must balance his desire for a normal life with his responsibility to protect and train the next generation of heroes. This thrilling isekai adventure blends action, fantasy, and mentorship, offering a fresh twist on the classic “summoned to another world” storyline.
