We started to learn more about Seiji in the last book, and in this one we finally finally! Start to learn more about Seiji's past and why he came to this school when he could have gone to any of the other ones. With that we also see Seiji becoming more a part of the team and interacting with them more. Nicholas's skills improve and we learn more about his past as well. The team dynamic is continuing to grow and we are truly seeing who is going to potentially make it to the national team.
