Tsubaki

Large eyes dominate Tsubaki's small, childlike frame. She wears her messy black hair pulled up into a bun; bangs split at the center hang along both cheeks and all but hide her ears. Her clothing shifts a little from panel to panel, but the usual look pairs light pants with a black shirt worn under a hoodie that zips up and has long sleeves.

Hardheaded passion drives everything Tsubaki does. Killing Titans is the strength she trains toward, and her constant demands for lessons grate on Murakumo. Nothing is off the table in her push to get into the Vanguard Corps. Her loathing of Titans runs deep enough that she will square off against several at once, unhesitating, carrying nothing but two knives.

Murakumo comes home to find Tsubaki already inside, waiting so the two of them can train. He turns her down; she refuses to drop it, telling him Titans ate her parents and she needs the power to destroy them. He relents just enough to set a condition: a hundred practice swings of the blade every day.

When Titans storm the city, she charges them in a blind rage. A giant hand nearly closes around her before Murakumo cuts in, ordering her back so her master can settle the fight. Despair floors her when a Titan devours him, and shock follows as he bursts free, transformed into a Titan himself. She shouts that the enemy's nucleus sits unprotected. Murakumo dies spending his last strength on one final strike, and Tsubaki, screaming but forcing herself steady, squares up to face the surviving Titan alone. Her master's parting blow turns out to be lethal; the creature dissolves into blood and steam.

Afterward she kneels at Murakumo's grave in tears, then dries them and starts her hundred daily swings, set on the Vanguard Corps and the extinction of every Titan.
