Zettai Ni Yatte Wa Ikenai Isekai Shoukan
Summary
Yaki Hiroshi has been living a mundane life, when suddenly luck struck and some guy playing a mobile game bumped into him, causing him to fall down - right in front of a train! Train-kun didn't kill him, though. Instead, it sent him to a world where a beautiful girl needed him. To die, that is.
