Chiro

Rurumo's familiar. Its appearance is that of a black cat. It understands human language and, in contrast to the taciturn Rurumo, speaks frequently in a fake Kansai dialect. It seems to be an important entity, not just a mere servant, as it knows things about the contract that even Rurumo is unaware of. It can temporarily transform into a dark-skinned girl using a transformation permit, but it has a habit of showing cat ears and a tail. Being a cat, its physical abilities are high after transformation. It admires Rurumo, who chose it as her familiar despite its unclear lineage, and sometimes plots to make Shibaki use tickets to help Rurumo regain her status as a witch.
