I picked this up on a whim because I liked the way the main character was drawn on the cover and I am happy I did. This is a fun manga and shows promise as a series. The premise is that in this world there are creatures called +Anima who look human but who each possess a certain gift: the ability to shift at least partially into the form of a specific animal. This volume introduces four characters: Cooro, the main character, a boy who can sprout the black-feathered wings of a crow at will; Husky, a boy who can breathe underwater and whose lower body can transform into a fish; Senri, a somewhat older youth who can transform his right arm into that of a bear; and Nana, a girl who can sprout the wings of a bat and who has some sonic voice power as well.
The author/artist, Natsumi Mukai, does an excellent job of making his (her?) characters sympathetic and individual. Cooro, whose outfit suggests some Native American influence, is relentlessly cheerful and adventurous. Husky on the other hand is rather androgynous, hates girls but loves to wear pearls, and tends to be sulky and easily annoyed. Senri, who wears a patch over his left eye, is calm, confident but unsettlingly silent, rarely speaking more than one word if he speaks at all, whereas Nana seems like she'll never shut up.
And all of these characters have mysteries about them. Cooro has some connection to this world's version of the Catholic church. Husky wears a pair of pearl earrings that appear to have some meaning for him. Senri's prize possession is a small book within which is a pressed flower of a type he appears to be searching for. And Nana apparently had to run away from an abusive drunkard father after a violent episode triggered her +Anima powers to manifest for the first time.
The stories in this volume deal mainly with their first encounters with each other, setting the stage for the longer series. The characters are likeable and funny, with just enough seriousness about them to give them the depth for you to care about what happens to them. If you like manga in general, you'll like this. Definitely a step up from the generic one tends to find all too often in the manga genre. Definitely recommended.
