"Listen, Kou-kun. Part-time jobs late at night is a violation against the school's regulation."
- —Towa's quote, Tokyo Xanadu
A new teacher who is petite and who gives off an in-high school-like appearance to some, as well as being Kou Tokisaka’s cousin. Towa is the hardworking type in charge of teaching mathematics and data processing. Though she’s new, she’s suddenly entrusted with a class of second year students, and serves as committee advisor and grade chief counselor. School officials trust her thanks to her extraordinary ability. On the weekends, she helps her grandfather Sousuke as a shrine maiden at the Kokonoe Shrine, and also teaches Kokonoe-style jujitsu at the dojo. Towa usually calls her cousin "Kou-kun", but has to call him "Tokisawa-kun" at school given that she is a teacher. But sometimes she will slip up and get teased by those around her.
- Her appearance and name resembles that of Towa Herschel from The Legend of Heroes: Trails of Cold Steel sub series but they are two separate characters.
- Tokyo Xanadu's Towa's name is only the same phonetically, her name written in Japanese kanji.
