Kotone buried her face in her hands, as much because of embarrassment as exasperation at the tiny girl in front of her. She asked people not to give away what they'd done, and here the doujin president was naming a room that nobody except for her used. Honestly...
"Please tell Takahashi that the aikido clubroom is off limits," the tall girl said, turning around and gathering up Nadeshiko's clothing--clothing that she was holding onto for the momen--before turning to Himawari, "And Kobayashi... please keep your girlfriend from doing anything stupid."
Nadeshiko's clothes were handed to Himawari before--without all that much subtlety--Kotone sat down in a corner, watching the only thing of interest in the room. That happened to be Nadeshiko... though if she was questioned on it, her defence would be that this was a martial arts clubroom, and she was triyng to work out how athletic Nadeshiko was. Not a convincing argument, but she could at least sound it.
