- "アガットさんも気をつけて, あんまり無茶しないでください！"
You take care too, Agate! Please don’t overdo it!”
- —Tita's intro quote, Trails of Cold Steel III
When I heard Estelle onee-chan is also going somewhere away form the country...It was so uncomfortable...I feel like we won't see each other again
Tita Russell is a child prodigy in orbal technology and supporting character in the Trails in the Sky trilogy.
Tita is a twelve-year-old girl with blonde hair covered by a red beret and goggles. She wears red overalls and shorts with a bag holding all of her tools. Her attire is mostly red with black stockings and a white shirt undernearth her overalls. She also comes equipped with an orbal cannon to fight off any hostile enemies.
In Cold Steel 3, Tita has grown much taller from her petite height to the height of an average teenage girl. She wears the Thors girls uniform sporting that similar towards high-school girl, wearing a red neck ribbon, navy vest and a striped-bottom skirt. While she leaves behind her red beret, she continues to wear her trademark goggles on her neck while sporting a light turquoise sweater coat sporting her status as an engineer. She wears Strega-brand sneakers given by Estelle and the belt originally worn by Joshua, to whom she considers her other family.
Tita is a very innocent girl who is very cheerful and cute in appearance to everybody she meets. She loves fiddling with machinery like her grandfather. Every time she sees something interesting in terms of technology, everything around her is zoomed out as she works on it like in a robotic phase. Even with her intelligence, she is still very childish and loving like a typical little girl who can be moved to tears.
Tita Russell was born and raised in Zeiss in southern Liberl. Due to her parents' common unavailability, she lives with her grandfather, Albert Russell, while inheriting most of her mechanical knowledge from him. She continues to learn from assisting her grandfather in the Zeiss Central Factory, while also helping Grandma Mao with the hot springs in the neighboring Elmo Village.
After meeting the Bright siblings during an orbal light repair job in the Kaldia Cave tunnel, Tita gets immediately acquainted after teaming up with them like "kindred siblings" during the Black Orbment investigation. When the ZCF was assaulted and her grandfather kidnapped, she meets Agate Crosner for the first time who only sees her as a liability, a fact she doesn't take after being declined to help rescue her grandfather. Tita still decides to follow Estelle and co. to the Carnelia Tower anyway, only for Agate to take the bullet while letting the kidnappers thus considering Agate's point that she was a liability. After Agate was poisoned from the bullet aimed at her, she watches over his recovery where overtime, she learns Agate sees Tita as an image of her deceased younger sister, in which his harsh words was to prevent the same tragedy in his past. From that point, Tita's relationship with Agate grows throughout the series and gathers snickers by many. She remains faithful with Estelle, Joshua and the many companions she meet throughout the final battles during the Coup d'tat and the Liberl Ark.
4 years after the Calamity of Liberl, Tita learned of some occurring disaster in the Empire from intel by her former companion Prince Olivert. Thus she enrolls into the Thors Academy Reeves II Campus as an "exchange student" despite her mother’s and Agate's opposition. She continues to study orbal technology in Class IX: Accounting Division under Towa Herschel's tutelage and Professor G. Schmidt's mentorship to learn about the Panzer Soldats and Combat Shells to fulfill her "promise".
