土間(doma) is the dirt floor which is an entryway area of a popular Japanese house, while 埋まる(umaru) means 'buried' in English. Thus her name is 'buried in a dirt floor'
in her 'Indoor' mode, she is the total opposite. She lets out of her secret otaku side and barely contributes in doing household chores. She acts lazy, eats junk food, and is obsessed with playing video games, reading manga and watching anime.
