Mike is a stray cat that tends to appear randomly all over town, depending on her moods. Like her friend, Haa-san, she favors the Kajiwara household for mooching off food, but tends to be more skeptical of Sora than her brother, due to Sora's habit of handing out food past its expiration date. She's a bit vain, often mentioning how fluffy her fur coat is, but is otherwise a friendly, if occasionally aloof, cat.
