The anime isn't really your typical sports anime, to put it shortly it's like Magical Madoka. There are several incidents that are touched upon and are very well written in. Your characters seem almost dislikable at the start however they grow and mature which you dont see in most anime . I highly recommend this as it shows how something as simple as soft tennis (unofficial tennis) is an escape for people who have very bad problems at home and their team mates help them cope with their issues in a healthier way.
