Hi! I have three manga I read before but I just can't seem to remember the names. the first manga is about a boy being able to separate from his body when he is dreaming. He goes to visit his ex girlfriend? the second manga is about a demon king who everyone is afraid of so they send maidens to his island. but he's not a bad person, and he makes a country from the island. the last manga is about a guy who falls in love with a the number one hostess and he decided to enter that world?
