Rei Batsubami
Rei Batsubami is a second-season original character who shows up as Terano Totobami's guide and butler—and basically her insurance policy in the fight against Kirari Momobami. She's a former member of the Momobami clan herself, which gives her some inside knowledge of how things work.
Nobody's entirely sure what she's actually after. The rest of the Momobami clan assumes she's out for revenge, probably because of the whole situation with the Batsubami clan getting cut loose from the main family. But Rei keeps her cards close, and her real motivations stay under wraps.
