Appearance

Unohana ordinarily presents herself as a graceful, gentle captain with a composed smile and a braid resting across her chest. When she enters battle, the braid comes undone, her long black hair falls loose, and her demeanor becomes markedly colder and more predatory. 135 281

• Long jet-black hair, usually braided across her chest. 135
• A vicious scar below her collarbones, exposed when her hair is loose. 135
• Wears a white kimono in combat. 310
• Carries a distinctively curved Zanpakutō blade. 137
• Her battle presence is accompanied by overwhelming killing intent, often described as blood-scented or blood-red. 134 138

Personality

Unohana is outwardly gentle, patient, and professional. As Fourth Division captain, she prioritizes treatment and evacuation, shows compassion toward Rukia before her execution, and remains calm even in dangerous situations. 52 53

Beneath that composure is Unohana Yachiru's ruthless, battle-hungry nature. She seeks lethal contests against worthy opponents, regards killing as the proper response to a serious enemy, and can terrify allies and foes alike with her killing intent. 134 138 418

Her relationship with Wu Biao rekindles her desire to improve. Rather than accepting protection or falling behind him, she repeatedly pursues greater strength to match his pace. 281 302 310
