Cross my heart and hope to die, I promise that I will never lie.
And if my promise ever does go, I
will give you my eternal soul.

During the Military Academy, she was close friends with Noel and Makoto. She's described as a straight A student, and has a rather no-nonsense personality. She's very serious and reserved, and is a member of the dignified Yayoi family. By the end of BlazBlue: Calamity Trigger's True Ending, she is assigned by Hazama to kill Noel and Jin. She originally appeared as a non-playable character in the Calamity Trigger Story Mode. In BlazBlue: Continuum Shift, Tsubaki heads to 13th Hierarchical City of Kagutsuchi to search for Jin Kisaragi and Noel Vermillion. Unbeknownst to Tsubaki, Hazama is just using her to gauge Jin's the Power of Order, and to push Noel further into becoming Mu-12.
