You know, those two can just stay in that world. Not like they will have a lot to do when they go back to their original world after 5 years in a different one.
@xironi I disagree! One of them is a vampire princess, the other one's a human princess, and the mummy, well....Hopefully she can take over his position when he's gone. They're all quite financially stable as per their statuses, and would no doubt have no problem taking care of their loved one's child. There is also no saying whether or not our protagonist could come back to this world later after returning to his own in 5 years or if he could change his mind in the meantime. ^.-
