yeah that's what I was thinking. It'd make for a funny moment though, if the girls catch her snoring during a slumber party or something and just flip out from it since she never snores.>>1575
As cute as that sounds, there's some moments in the anime where Kagura falls asleep during trips. It might be cuz she's sitting up and she's in the background, but she's dead silent when it happens. Also she drools on her way back from Okinawa.
Yukari snores each time she's depicted sleeping and eventually lets her limbs go all over the place.
