Poor Tooru. Her birthday happens to fall right around the time of testing. This episode was of the sort that felt like K-ON! or Kanamemo. Sure, it manipulated my emotions, but sometimes, I don't mind having my emotions manipulated just a little bit. It's not like it shuts down my brain. Quite a lot of this episode was spent en flashback, and seeing the uniforms of the schools Nagi and Yuuko attended before they came here was nice. Yuuko was always a target of humiliation, even before she had really met Run and started getting wasabi-filled cake.
The end of the episode, with Run realizing next year her friends will be third years, made her the Azusa of this group. Pangs the heart. Don't worry, Tooru. Even if I have to do it myself, I'll write you out a pleasant future. Think of Yutaka and Miporin as your Ui and Jun, and know that your old friends will never be forgotten, and new ones can always be found. These bonds are unbreakable, as expressed in this week's song, "Zutto Kitto Motto" (add one more "Motto" in there and it becomes something else entirely.) by Yuuki Aoi.
Even if there is only one more week, that's okay. Their adventures will continue, even if we're not watching.
