|Affiliation|| Mouri House, JAPAN|
|Appeared in||Sengoku Rance, Rance Quest|
One of the three sisters and also the oldest of Mouri's daughters. Teru is implied to be the most violent, yet also the most level-headed among her sisters. Aside from her primary role in the family as cleaning-maid, she can also being Motonari's one and only personal adviser, whether it's about his personal health or war tactic.
Her hobby is cleaning, and she tends to be perfectionist at that. That hobby of hers is ironically contradicted her second hobby, which is killing.
Despite of that brutal image of hers, she is still very concerned with Motonari's health issue. She loves and respects her father as much as her sisters do.
Teru's first appearance is during the first Mouri House's introduction event, in which she clearly shows her violent side along with her sisters. As the oldest, she tends to act as Motonari's personal adviser and she is very over-protective toward him.
Teru is responsible for taking care of the hygiene of Mouri's residence, and she is very perfectionist at it. While Teru does consider Motonari's actions as reckless, she still believes in her father's own power, that's why she accepted Motonari's idea to offer a duel against Oda's main force. Just like her sisters, it's only possible to capture her after that battle.
During one of her events, she said that she wouldn't have been motivated in cleaning if it wasn't for her mother, who wanted her daughters to be womanly. Knowing how her husband is well enough, she taught all of her daughters in the one thing they're most likely good at, with Teru taking the cleaning, Kiku with the cooking, and Chinu in etiquette. For the same reason, they all have to wear maid outfits.
Teru is one among very few girls who could lecture Rance.
