Stella has long brown hair and brown eyes. She usually wears a white dress with hints of yellow, and a necklace with a yellow butterfly on it. She also wears yellow slip-on shoes.
Stella is shown to be quite intelligent, and is also quite beautiful. Her mother takes many photos of her and her brother, in the hopes of them becoming famous. She is also very kind and shy, like her older sister, Kaori. She also has to work at the Oishii Tabemono Restaurant.
Stella first appears when Kaori enters the Oishii Tabemono Restaurant, and was at the counter, reading a book, while her brother Ken was drinking a milkshake. When Kaori explained her problem to her mother, Ken said that she should write a story about him (with Stella rolling her eyes), which Kaori quickly refused. Stella then says, "Mother used to be a reporter. Ask her.", and Kaori does.
- She was seen reading Pirate Hurricane, a book that Akimoto Komachi wrote.
