Written and illustrated by Nari Kusakawa, it's an interesting manga with an odd but colorful (heh) plotline.
Summary:
On the island of Opal lives the world's most colorful birds. The birds have attracted a school for aspiring "Palettes"- wizards who have the ability to borrow color from one object and paint its qualities on to another. Young Cello has the potential to be a great Palette, but she just can't seem to control her power. As the end of freshman year approaches, she's on the verge of failing, so she's going to need all the help her bird YoYo can provide!
I don't like the backs of manga to tell me what it's about.
I prefer to look at the style of art.
This art style is...kind of sketchy. It resembles Bisco Hatori's style. (The artist of Ouran High School Host Club)
But I like it.
It's an interesting plotline, and it doesn't have all the woo-woo wand stuff that you'd associate with magic/wizards.
