Lovely Muco! is a black & white manga that’s written and illustrated by Takayuki Mizushina. It’s also popular enough to have been adapted into an anime series already. “In the beautiful mountains of Akita stands Glass Studio Amato, run by Mr. Komatsu and the shiny-nosed dog who loves him — Muco!! Muco dreams of the day when Mr. Komatsu will become a dog, too, but in the meantime she spends her days chewing up towels, jumping in the pond, and inventing new games…all called ‘Komatsu’! Based on a real person, a real dog, and a real glass studio, there’s something here for everyone—even cat lovers!” And the manga’s still available from Penguin Random House.
