"Hatsune Mix" is a collection of short stories with a very cute drawing style. (*girl's opinion here*)
The Reader is introduced into a World of Music.
For example, Chapter 9 alludes to the Song Little Mermaid, giving the Mascots of Yamaha's Synthesizer Software a Soul, a Personality.
Every Chapter shows different sides of the Characters, mainly Miku.
Sometimes the Vocaloids are portrayed as a family, sometimes as lovers or simply as "robots".
Sometimes they can be cheerful, sometimes depressive.
Sometimes they are nice and helpful, sometimes mean and heartless depending on the context of the chapter. >especially Meiko changes between the enemy and ally.
In my opinion, Hatsune Mix is suitable for every Vocaloid Fan. If you don't like a story, you can easily skip it and find another very good chapter.
