Shinobi Life End

From Konnichiwa:Many, many years ago, a ninja named Kagetora devoted his life to protecting Princess Beni (”Beni-Hime”). Unfortunately, they were attacked and Kagetora was flung into a lake, and sank to the bottom… And is somehow warped to the future where he sees the princess Beni being kidnapped.Little does Kagetora know that Beni is not the real princess, but rather her descendant. Beni, on the other hand, thought that Kagetora was just a cosplayer. Beni, the daughter of a rich man has already been kidnapped a hundred times already... But fear not because Kagetora is here. Will Kagetora be able to go back to the past, or will he remain by Beni’s side forever?
