Stella Redfield (ステラ・レッドフィールド, Reddofīrudo Sutera) is a supporting character of the Boku wa Tomodachi ga Sukunai series. She is a steward of the Kashiwazaki estate, though she is primarily seen fulfilling the duties attributed to a butler.
As revealed in the CONNECT novels, Stella is Noel and Tenma's daughter, making her Sena's half-sister. To cover-up her blood ties with the Kashiwazakis, Stella usually introduces herself as a distant relative or a member of a family that has served the Kashiwazaki household for generations.
She is a fairly young woman (as Kodaka said "in her late 20's at the oldest"). She is slender, a bit short and has neck-length blond hair. Her eyes are a transparent blue color, similar to that of Sena's (traits she inherited from her mother).
She usually wears a standard-looking female butler uniform. She has a habit of showing an expressionless face.
Stella seems to love teasing people (making many straight-faced jokes), especially Kodaka (telling him that he is perverted whilst knowing that he is not, and giving him a condom while he was studying with Sena in her room). Though her teasing also serves to put people on the spot, such as the case with her master/father Tenma (e.g. pointing out uncouth behavior and reminding guests of his undesired nickname).
Nonetheless, Stella is quite a responsible and competitive worker, showing great knowledge of her masters' personalities and habits; whilst also having a habit of speaking in a monotonous voice.
She also claims to sleep fully nude, which she has openly stated to Kodaka such as the time when he and his sister spent the night in the Kashiwazaki estate, though this may also be attributed as a joke or tease in Stella's part.
Stella is an intellectual prodigy, having graduated from college at the age of fourteen. Though it is unknown as to how she applies her gift in knowledge into practical use since her job as a steward limits her to only doing housework.
Having been raised in England, Stella may be bilingual, being proficient in speaking both (though not shown) English and Japanese.
Stella is a butler and steward and as such, has all the associated qualifications and abilities one would associate with someone having these roles. She has all the requisite skills and knowledge to run and keep the entire mansion in order without assistance; whilst she also seems to have a reasonable sense of style and knows what attire would best compliment an individual.
Stella is also to noted to be a learned driver.
- Though written as ステラ, Stella's Japanese name is Suteru 寿照蘭.
- Stella has an unnamed lover that has yet to make an appearance in the series.
