honestly an 7-8 going by the plot but because chisato is so cute it becomes a 9. story line reminds me somewhat of guilty crown where it seems interesting at the start but then once the pieces are in place it becomes very 2 dimensional. Still a good time-waster and if you're looking for a new waifu though. chisato best girl personality i've watched in anime, and i've been watching anime for 10 years. i think if you like a cheerful girl personality with lots of bounce and good fanservice this is the show for you. cheers. also season 2 has been confirmed so morereason for you to watch it tbh.
