When Katie overhears a tense conversation between Tomohiro and another student, and in a fit of anger, papers are thrown all over, with one landing near Katie. The drawings on the page appear to move.
Katie is curious about Tomohiro despite her friends' warnings--he is known to be violent, and possibly got his ex-girlfriend pregnant. Bad boy alert! Katie and Tomohiro's paths cross, and she is increasingly inquisitive of his drawings and the strange things occurring around him. Ink blends Japanese mythology, this idea of drawings coming to life, as a sort of paranormal plot within the romance. There are a ton of Japanese words and phrases that can make for slower reading, but it's a great "outsider's" look at Japanese culture.
And lest Katie be just another fangirl of a hot, brooding boy, she actively puruses Kendo (a martial arts) and may have an ability of her own.... This is the first in a three-book series.
