Reincarnated as a sub-character of a video game that I used to play!? After saving a girl and then getting run over by a car in the process, and I was reincarnated in Rex in a video game world. A handsome Rex with skills in all fields, but he is a helper character in the early stages. Tho Rex has a high level, balanced skill set and multitude of abilities...Hes useless in the later stages of the game!! I decided in the face the fact that Im useless in this fantasy world So lets relax by letting the main character of the game do both saving the world and fighting for his life against monsters!　 This is a story in which an ordinary person looking for a hero but instead becomes a hero who saves the world for some reason!
