He initially thought the "Another World" was a world completely different from the surface world, plagued by demons and monsters. But when he discovered the people seeking help included an elf princess and her protective knight, a snow woman who couldn't pay her rent, three succubus sisters who wouldn't let anyone touch them, a mermaid singing idol group, and a ghost's childhood sweetheart, he was shocked to realize what this "Another World" was like!?
