It figures when I need to talk about a good but overlooked shojo manga from the past, I can always turn to CMX.
CANON (Kanon), by Chika Shiomi. First published in 1994 and first published in North America in 2007.
PLOT:
Six months ago,
Canon’s classroom was attacked by a mysterious vampire. All of her classmates were drained in an instant, while Canon was transformed
to a vampire. Through sheer
willpower, she has managed to contain her hunger and now uses her supernatural powers to
save others and hunt down the man who transformed her. The only ones able to help her are Fui, a
sassy vampiric crow, and Sakaki, a fellow vampire with an agenda of his own.
