MISATO:“Oh, to the wedding?
I wore the pink suit for Kiyomi's wedding,
and the dark blue dress for Kotoko's
just the other day.”
WOMAN (OFF):“Synch rate is normal.”
UrsusArctos: As noted in the Character Name Origins page, Misato's name comes from Minako Narita's manga Aitsu and I suspect that goes for Kiyomi and Kotoko too. Never been able to confirm it, though.
