The Guardian Spirit (守護霊様, Shugoreisama) is a big bunny, who is said to be the god of thriving business, hailing from the moon.
He's a big white fat rabbit with a crescent moon mark on his forehead.
Refuto and Raito attempted to summon him from the moon on the night of the autumn Crescent Moon, using Moon Dumpling placed in an altar to be offered to him, in hope of learning an incantation that can make their business thrive. Their attempt succeeded with the use of Rinne, protecting the dumplings from ghosts, but he refused to eat the dumplings. And even though the twin rabbits managed to force him to eat them, all he said was advising them to get a part-time job and left.
