Dogs and heroes don’t dress up

After being summoned to another world to defeat the Demon King, 18-year-old Satou Sousuke returns to Earth years later, having completed only elementary school. Unable to find a job, he gets by on part-time work. When Sousuke comes across a magician battling a demon—creatures he thought did not exist on Earth—he defeats the demon with ease. His power draws attention, and he is soon caught up in the effort to subjugate demons.
