A Shinobi's Journey

A man retired from the army was kinda killed during his sleep. He then reincarnated into the World of Shinobi with a System to accompany him. This is just a cliche story with cliche plot and cliche twist. ×Disclimer× I don't own any works used in this Fanfic. If the owner of the said works tell me to take it down, then I'll do as they say.
