NaNaNa Najahkoop

is a Quincy and a member of the Wandenreich's Sternritter with the designation "U".

Appearance
NaNaNa has long, dark hair, which is arranged into five fanned-out spikes, and unusual teeth which alternate between black and white. The rest of his upper facial features, including his eyes, are covered by a smooth mask with a reflective surface. His attire is a variation of the usual Sternritter uniform, including the order's signature hooded-cloak with its right side bunched atop his shoulder, revealing a small shirt beneath which leaves his abdomen and thin arms bare. He wears a pair of white, high-waisted pants and boots, and has a ring on each of his fingers and a bracelet on either wrist.

Personality
NaNaNa has little issue with criticizing his fellow comrades, including those of the Sternritter. By his own admission, he has no understanding of art. He is quite arrogant, claiming he could defeat 3rd Division Captain Rōjūrō Ōtoribashi within five minutes.

The Thousand-Year Blood War arc
Upon receiving the orders of Yhwach, NaNaNa and the other Sternritter gather at the Gate of the Sun before traveling to the Seireitei in order to participate in the conquest of Soul Society. Once there, he and the others create pillars of blue flame prior to engaging the Shinigami in battle. Encountering 3rd Division Captain Rōjūrō Ōtoribashi, who has just received word of casualties in his division, NaNaNa asks him if anyone died, but Rōjūrō refuses to answer. In a brief exchange of words, both declare the other will soon be dead.

Later, when Captain-Commander Genryūsai Shigekuni Yamamoto confronts Yhwach, NaNaNa, Äs Nödt, and Bazz-B attempt to ambush him from above. Stating it was naive of Yamamoto to face Yhwach alone, NaNaNa and the others attack, only to be incinerated by Yamamoto's Ryūjin Jakka. Surviving this attack, NaNaNa is later present when Yhwach appoints Uryū Ishida to be his successor, which shocks him.

Powers & Abilities
Great Spiritual Power: NaNaNa's spiritual power is on a level comparable to or greater than that of a captain-level Shinigami.
