Enmu Tamio is an extreme train connoisseur. He loves everything about trains, but he keeps coming back to the Mugen Train because of nostalgia. He feels "Connected" to trains and doesn't call this a hobby, more like a profession. Its noted that he's been convicted 6 times for doing " perverted things" inside the trains themselves, a strange kink, so most people are weary of him. Regardless he doesn't care what others think and keeps continuing his "profession" of studying and enjoying the trains
