Chiro

She's Rurumo's magical familiar, a purple-furred cat. Chiro is the one that informs Shibaki that once he uses up all 666 tickets that Rurumo gave him, he will die. She is able to transform into a human girl at will, in which form she becomes a tan-skinned teenage girl. She used to be a stray cat, who tried selling magic wands for a living, but Rurumo offered her to become her familiar, for which she's very thankful.
