Mina represents Fukurokuju. The two are twins and the youngest members of the club, as the only elementary students. They have a tendancy to fall over and go to sleep if they expend even the smallest amount of energy, which they seem to lack, except when they transform in which case they are full of energy. Because they represent the two gods Fukurokuju and Juroujin (who are the gods of luck and fortune) they are almost the same person. Details about the twin's relationship are in episode 6.
