I just assumed Takumi was a girl at first because it's a yuri collection, and the rest of Canno's stuff that I've read have all starred girls. I was like, "Huh, she's pretty tall." Or "She's pretty androgynous in general, isn't she? Cool!" And even "Is she wearing trousers with her uniform? Wait, isn't that actually the boys' uniform? Why would a girl be wearing it? Is it going to be a character thing?" Took me fully half of the story before I even realised it might just be a guy. Whoops.
Anyway, like a lot of Canno stories, it was a pretty interesting setup, but didn't really go anywhere. I get the feeling Canno really likes making up new characters and new scenarios, but starts to drag when it comes to actually following through on those characters with stories and events.
