i assume she disappears into the aether at night where their dad spends all his time, only to rematerialize when natsumi is making a racket.
we get to see glimpses of the other 3 tatami rooms and they're completely empty
i initially assumed maybe the bottom right tatami room was where their parents slept because they'd always take this long path from the kitchen to the main living room when bringing in food, but in nonstop yukiko takes a direct path through the bottom right tatami room giving the first glimpse of it and it seemed empty.
but there was a single scene where it seemed like the light in that room was on, so i will maintain that it is the most likely candidate for the parent's room
