A female character from the Haruhi series formally introduced in The Intuition of Haruhi Suzumia (Suzumiya Haruhi no Chokkan).
T is a second year high schooler and foreign exchange student with long blonde hair and blue eyes. She came to North High during the Spring of Kyon and Haruhi's second year of high school. She is a member of the North High Mystery Research Club.
T is first introduced in the 2018 short story Seven Wonders Overtime, but was left unnamed because Kyon refused to introduce her or let her introduce herself. In the 2020 story Tsuruya's Challenge, a new story a part of the The Intuition of Haruhi Suzumiya, she is formally identified with the nickname "T".
Kyon finds her annoying, especially because she refers to him by the nickname Kyam.
- T's full name is introduced toward the end of Tsuruya's Challenge and is Ottilie Adrastea Hohenstaufen-Baumgartner, which was shortened all the way down to "T" by her classmates.
- T is really close friends with Tsuruya and her family has close ties with the Tsuruya family business.
