Power equal to Yhwach's level	292	His overall level was stated to be no longer inferior to Yhwach; fate- and causality-based powers could not define his destiny.

Background / History

Natsuki began as a Plus who accidentally fell into Hueco Mundo. Watanabe Yuji nurtured him during his five-year stay there and later ensured he entered the 11th Division upon returning to Soul Society. Though he had no Shino Academy education, Hueco Mundo gave him foundational combat training and real battle experience. 78 253

He rapidly rose through the 11th Division, serving under Kuruyashiki Kenpachi before challenging Kiganjo Kenpachi. After killing Kiganjo, Natsuki became the 11th Kenpachi. 54 78

As Kenpachi, he actively recruited and cultivated talent rather than relying solely on personal strength. He recruited Yadomaru Lisa from Shino Academy, later accepted Tosen Kaname, Ichimaru Gin, and Matsumoto Rangiku into the division, and trained Zaraki Kenpachi through repeated life-and-death battles to awaken his sealed power. 57 126 167 169

Natsuki repeatedly opposed Aizen Sosuke, preparing specifically for Illusion by learning to fight with his eyes closed. He exposed Aizen's threat, countered the latter's hypnosis, and ultimately helped the Gotei 13 defeat him by evolving his Bankai to nullify Aizen's illusion and space-time powers. 97 149 150 234 235

After surviving the Reishi Storm in Hueco Mundo, Natsuki traveled through Hell and returned with its power embedded in his soul. During his later battle with Aizen, he fused Hell, Soul King, and Shinigami powers, remaking his body after destruction and reaching a new evolutionary state. 214 220 231 233 240

Following later conflicts, including clashes with Yhwach and Aizen's return, Natsuki retired while continuing to intervene when the stability of the Three Worlds was threatened. 292 300

Appearance

Natsuki is described as a sunny, dashing young man whose youthful appearance contrasts with the intimidating aura of a Kenpachi. 57

• Wears a Captain's haori as captain of the 11th Division. 77
• His Reiatsu commonly manifests as blood-red or crimson mist and a veil around his body. 83 150
• After reconstructing his body during the battle with Aizen, he appeared in white robes resembling Rukia Kuchiki's Senzaikyū attire. 233

Personality

Natsuki is calm, practical, and highly strategic. Even as a Kenpachi, he treats combat as a means to grow stronger, protect allies, test enemies, and develop others rather than as an end in itself. He recruits for administrative potential, researches equipment with Urahara Kisuke, and prepares countermeasures against abilities he has not yet encountered. 53 97 102 120

He is respectful toward mentors such as Unohana Retsu and Yamamoto Genryusai, but does not defer blindly to authority. He openly defied Yamamoto when pursuing Aizen and later sought to spare Unohana's fate by restoring Zaraki's power himself. 55 56 150 169

Despite his strength, Natsuki remains humble about victories and credits assistance when it is deserved. He also shows compassion toward vulnerable souls, saving Ichimaru Gin and Matsumoto Rangiku in Rukon District and encouraging them to become Shinigami so they could protect what they cherished. 92 162 163
