Synopsis from My Anime List
Tokyo Regional Legal Affairs Bureau Census Division, Annex 4 also known as SCEPTER 4 is a police institution that aims to stop criminals with special skills. But for them, their real target are…?
Of course after reading K- Memory of Red, I had to read K-Days of Blue. the format is quite similar. Each chapters have is own story with the exception of chapter 5 and 6 which is a two-part story. As the title implied with the word blue, all the story evolve around Scepter 4.
As I said each chapter have is own story but it still follow a certain timeline. Chapter 9 mention Totsuka‘s death while chapter 10 have a mention for Mikoto‘s death. There is also mention of the time since alarm clock can be seen in the different chapters. I could talk about the character, but since this manga is should be read after watching the series, there is no point to talk about it. However I can say that one of the main character, if not the main character, of this series is certainly Fushimi
It a really nice complement to the series, seeing the Scepter 4 interact with each other outside the main story was a real delight.
