Books like Is It Wrong to Try to Pick Up Girls in a Dungeon? Manga, Vol. 3

The harem aspect of the story has taken some strange turns with this volume, with the introduction of a mysterious new character who has become the hireling/assistant of Bell. There are already several mysteries about that character and the Familia with the desperate need for money, so I'm hoping those are developed in the next few volumes.Even the other goddesses think that Bell's cute, so it's no surprise that mortal women keep flirting with him.I want to find out more about the real back story of the goddesses, though, as some things are clearly not adding up, in terms of their supposed story.
