Tentetsuki: Train To Another World

On the way to Tokyo, a 17-year-old college student, Ichiro Mushibami suddenly ended up in another world after riding a bullet train. It wasn't just any parallel world. It was the world of Tentsetsuki, the game he had always been playing. A world set in a war between a Kingdom and an Empire, a premise that was similar to the game Ichiro was playing. In the world of the game, Ichiro learns that leveling was never easy, falling short of the fantasy of being overpowered after being transported. However, as the war in that world progresses, Ichiro is pushed away further from what he wanted; to go back home.
