I Have a Hotel in Another World

The system took him to another world, and now he is the host of a hotel where the guests are characters from all the different fictional novels like One Piece, Naruto, Dragon Ball, and Marvel.

"Rock Lee, what happened to your hair? Why are you doing the One Punch Man training?"

"What did you say? So Jiraiya is married to Tsunade, and the Fourth Hokage didn't die because Jiraya knocked the beast out with a single slap on its face?"

"Sanji from One Piece knocked everyone out with Conqueror Haki during the battle of Marineford? Should it have been Luffy instead?"

These changes in the countless world are due to one hotel host from another planet.
