Colonel Monochrome

A cat that the girl pick up in the first episode.

Personality
It seems to be completely passive when the girls pick it up. In other times it doesn't display any unique behavior, mostly strolling from place to place.

Appearance
the cat is colorized like a panda bear. I seems to be very small as the girls can hold it up pretty easily.

Trivia

 * The girls call him a "monster cat" and "cat burglar" sometimes.
 * Colonel doesn't like Sat-chan.
