I definitely didn't enjoy Days of Blue as much as I enjoyed K -メモリー・オブ・レッド- 1, but this manga still holds it's own. The plot line was beautiful, the characters deep and the backstory so emotional. Yet another series within the K series that has made me cry.
Days of Blue is much more beautiful than Memory of Red, I would even say etheral. It has a delicate beauty that isn't much seen in manga much anymore. The story line flowed beautifully, tying in with the events of Memory of Red and I have never seen such tie ins that flow so much in their own stories whilst joining on to a much bigger universe.
Days of Blue is definitely one of those manga series where I say read both volumes. Do not miss this series. My heart and spirit has truly been touched, and I thank Gora for writing this series.
