Witch Life in a Micro Room, Vol. 1 (manga)

Madge and Lilika are fledgling C-rank witches who can only afford to share a measly 99-square foot apartment in the big city. They scrape by doing bottom-of-the-barrel jobs and eating just cabbage for dinner. But the two girls are serious about improving their lives so that they can get a pet, buy a bunch of grimoires, and eat some meat! All they need is some elbow grease!
