Rei sits silently in her school swimsuit, indifferent to the excited voices.
Reichu: Originally, Rei was supposed to be sitting in her school uniform. Also, when the storyboard was done, the final girls' uniform design hadn't been decided. Here's the econte for C-114, just because you get a clearer look than in 106.
NemZ: Hmm, that's interesting. Might suggest she's she was intended to still be slightly injured and thus excused from participation.
Kendrix: Again, this anime's uncanny ability to evoke images/scenes everybody has seen... that one kid sitting at the side during PE class while everybody else is having fun and interacting because she's neither good at interacting nor at sports, the latter perhaps because of a disease. This shot immediately called up memories of authentic ppl I know in real life, in fact, I know that situation and what it feels like myself...
