Until this point, we have seen how Fencing is mainly a solitary sport with the person being up on the stand alone against an opponent. However, there is a team element to it and we get to see that more so in this one as they compete against one of their biggest rivals. 
With this, we get to see Harvard's leadership as well as how Nicholas does under pressure, and of course Seiji's skill set as well. Having said this though Seiji is still not the best team player, and is still focused on the individuality of the sport it seems where as Nicholas and several of the others enjoy the team part of it more. 
Like in the other ones learning Fencing through this graphic novel series has been fun and I loved seeing it in action.
