-Masami's room has light purple walls decorated with a few posters for shoujo manga and TV dramas. She has posters for both the original manga Yukiko to Kanji and its TV drama adaptation. The rest of the posters are for incredibly sappy shoujo manga(like Moe Boyfriend), incredibly sappy dramas(like Confession Daisakusen), and jidaigeki series(like Sanbiki ga Sasu!).
Her room also has a sword rack with two identical katanas, a bookshelf filled mostly with shoujo manga(she has the entire collection of Yukiko to Kanji), a smallish closet for clothes, and a coffee table in the center.
Masami's bed is larger than one would expect her to have, with no fewer than 10 pillows on it(it looks like the pillows take up more bedspace than Masami herself has room to sleep). There is a small nightstand by the bed, which actually seems to only be there as a surface for tea-related stuff.
On the side of the room opposite the door to the rest of the house is a glass sliding door that leads out to a small balcony with a table and a few chairs, overlooking a majestic landscape which changes seemingly every day. It also has two large windows on either other side, showing similar landscapes.
-Masami has a bunch of kendo gear in the gym and has 2 whole cupboards full of nothing but tea in the kitchen, as well as a water boiler. She has a beanbag in the common room big enough for her to lie down on while stretching her legs out under the kotatsu. She has a section in the garden not unlike the garden from her dungeon, full of cherry trees in perpetual full bloom.
-Early in the day and late at night Masami is usually in the gym training. She spends a great deal of time sitting at the kotatsu drinking tea and reading shoujo manga. She has a set schedule of TV dramas that she always watches, usually in the common room. She can also commonly be found in the garden or the pool. She is in the game room on occasion. She stops in the kitchen a few times a day to switch up her tea and will cook every once in a while.
-As one would probably expect, it is pretty rare to find Masami without a travel cup for her tea and a thermos for refills. She is somewhat social, but hesitant to get involved in other peoples' business uninvited. She sleeps less than most of the others at night, but makes up for it by taking a short nap during the daytime on most days. She'll visit certain characters at their rooms on occasion.
