In this episode, we see Hisone in conflict with Nao Kaizaki, another D-Pilot cadet who does not like Hisone at all. Because of this, she wants to make Hisone's life at the airbase miserable. Along the way, though, we do see a softer side of Kaizaki, and it's these moments that make me root for her as the series progresses. Overall, a solid, emotional episode!

P.S. I love the ED as well!
