This is a spoiler free review for the whole series as I don't like rating individual volumes and would rather rate the series as a whole. 

Ah this series, I have such conflicting thoughts on. Firstly, the art is amazing. It's so fun, it conveys the characters perfectly, and some panels are so detailed and gorgeous. The plot for the most part is also really interesting and engaging, and I enjoyed the the characters development and where they end up. It'd maybe be a 5 star series, however, there is a slightly weird relationship situation played with along the way that would be very inappropriate but nothing ever happens and so it's sort of just there to develop the plot in a certain way. It's not bad I'm just never sure how I feel about it as a plot device. Otherwise a great read and maybe figure out for yourself how you feel about it!
