Tsukuyo is a child prodigy that skipped several grades, making her the youngest member of the Tenka Goken. Despite being so young, however, she is unquestionably the strongest member. While blind, she has excellent hearing, to the point that she is capable of hearing most things going on in the academy. Even though she carries a calm and collected demeanor, she can still act childishly, much like the many instances where she likes to show off her knowledge resulting in long rambles. Tsukuyo is a skilled user of the Yakumaru Jigen-ryū, the descendant style of the Jigen-ryū that Nomura practiced.
