Escalate

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 colorful life. If Hachi can help Aoi open up, unlocking new feelings in the process, maybe his life won't be so bland, after all. ***Note:** Monotone Blue is the serialized version of a oneshot named "Escalate", published in the [Kemono/Jingai BL Special](https://www.mangaupdates.com/series.html?id=150990) anthology.*
