NaNaNa Najahkoop

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

Appearance
NaNaNa has long, dark hair arranged into five fanned-out spikes, and unusual teeth that 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 Sternritter's typical white uniform, including the order's signature hooded-cloak, though the right side of his is bunched atop his shoulder, revealing a small shirt beneath that leaves his abdomen and thin arms bare. A pair of white, high-waisted pants and boots complete his clothing. He 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 also quite arrogant, claiming that he could defeat Rōjūrō Ōtoribashi, a captain of the Gotei 13, 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 to participate in the destruction of Soul Society. Once there, he and the others create pillars of blue flame prior to engaging the Shinigami in battle. Encountering Captain Rōjūrō Ōtoribashi, who had just received word of casualties in his Division, NaNaNa asks if anyone died, but Rōjūrō refuses to answer. In a brief exchange of words, both declare that the other will soon be dead.

When Genryūsai Shigekuni Yamamoto later confronts Yhwach, NaNaNa, Äs Nödt, and Bazz-B attempt to ambush the Captain-Commander from above. Stating that it was naive of him to face their leader alone, NaNaNa and the others attack, only to be incinerated by Yamamoto's Ryūjin Jakka. NaNaNa survives this attack, however, and is later present when Yhwach appoints Uryū Ishida to be his successor. Like the other Sternritter, NaNaNa is shocked by this announcement.

Powers & Abilities
