Monotone Blue

Hachi the cat finds most things monotonous, but at the top of his list is high school and all that comes with it. But when Aoi the lizard - a quiet, high-achieving transfer student - arrives, Hachi catches a glimpse of a brighter, more colourful life. If Hachi can help Aoi open up, unlocking new feelings in the process, maybe his life won't be so bland, after all.
