Tsubaki Yayoi is Jin's childhood friend, Noel's and Makoto's former roommate from the Military Academy, and a first lieutenant of the non-official Novus Orbis Librarium's Zero Squadron. She originally appeared as a non-playable character in the story mode of BlazBlue: Calamity Trigger. However, since BlazBlue: Continuum Shift, she became a playable character. She is a member of the Yayoi family, one of the 10 families of the Duodecim.

Tsubaki is a serious, mature, and intelligent person. She has always followed her orders from the NOL and has complete faith in them (likely to honor her family name). She has always had a childhood crush on Jin, and deeply loves and cares about him. She was also good friends with Noel, Makoto and Carl Clover when they were at Military Academy. However, when Hazama told Tsubaki about the alternative timeline where she was always with Jin as his secretary and how Noel usurped that position away from her, she becomes extremely jealous. She begins to harbor a hatred toward her best friend that, once manipulated by Phantom's sorcery, evolves into a desire to kill her in order to be with Jin. Even after changing sides, she still respects Hakumen despite sharing different views.

In BlazBlue: Chronophantasma, Tsubaki's personality had almost been completely overwritten by the effects of Mind Eater, the spell that Phantom cast on her in order to allow the Imperator to control her directly. Her devotion to the NOL had been taken to its greatest extreme, and she was little more than a mindless drone who lived to carry out any and all of the Imperator's orders, including killing her own friends. When Jin confronted her, however, she showed signs of resistance due to her feelings for him./
