NaNaNa Najahkoop

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

Appearance
NaNaNa has long black 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, red-orange 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. NaNaNa is a very wary and cautious individual; while Renji Abarai was sleeping, he patiently waited an entire night because he falsely presumed Renji had set a trap.

Despite having been left for dead in the Seireitei by Yhwach and having his powers stolen by Yhwach's Auswählen, NaNaNa is blindly loyal to him, still trying to prevent the Shinigami from hindering his plans even after this betrayal.

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 flames 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.

During the next attack on the Seireitei, NaNaNa notices the defeat of Mask De Masculine and goes in search of the person who defeated him. He finds Lieutenant Renji Abarai holed up on a building, apparently asleep. Suspecting a trap, NaNaNa simply observes the lieutenant and is surprised that he genuinely slept until morning. After Renji leaves, NaNaNa criticizes him for sleeping in the midst of the enemy camp and notes that he has never observed an opponent for so long, before stating that the "red monkey" will soon be finished.

Later, NaNaNa, PePe Waccabrada, and Robert Accutrone confront Ichigo Kurosaki alongside five other Sternritter and prepare to battle him. After Ichigo gets away from Meninas, NaNaNa leaps into the air and smashes his hands into the ground, forcing Ichigo to dodge. After Renji arrives, Ichigo departs to confront Yhwach, prompting NaNaNa and Bazz-B to attempt to follow him. However, they are interrupted by the arrival of several more Shinigami. Soon afterward, NaNaNa rushes toward the Shinigami alongside the other Sternritter, who have activated their Quincy: Vollständig. 6th Division Captain Byakuya Kuchiki soon defeats him, and afterwards, NaNaNa has his powers stolen by Yhwach's Auswählen.

Soon afterward, NaNaNa, Bazz-B, Liltotto, and Giselle confront the Shinigami attempting to bring down the Soul King Palace, with NaNaNa incapacitating Sōsuke Aizen. When Shunsui Kyōraku notes they will have to fight, NaNaNa attempts to paralyze the rest of them, only to be interrupted when Bazz-B shoots him through the chest with Burner Finger 1. Cursing Bazz-B, NaNaNa collapses.

Powers & Abilities

 * NaNaNa can analyze the Reiatsu of a target over a certain period of time, allowing him to determine an opponent's spiritual power distribution. After doing so, he imprints his epithet letter onto his target and uses it to form a grid pattern, which he dubs his . The grid allows him to pinpoint the holes in a target's Reiatsu and attack them, increasing their size until the target's Reiatsu depletes. This allows him to paralyze and knock them out. The more time he has to analyze them, the more effective his ability is.

Reishi Manipulation: As a Quincy, he primarily absorbs spiritual energy from the atmosphere, and combines it with his own spiritual energy to form weapons. He has an easier time collecting this energy in environments with higher concentrations of Reishi such as in Soul Society or Hueco Mundo.

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

Quincy: Vollständig
Although only partially seen, upon activation, NaNaNa's Quincy: Vollständig grants him a pair of looped, ring-shaped wings composed of Reishi. Upon being a sacrifice for Yhwach's Auswählen, he lost the ability to use the Quincy: Vollständig.


 * Flight: Using his wings, he can fly at high speeds.

Quotes

 * (To Rōjūrō Ōtoribashi) "Sorry, man. I don't get any of this art stuff. But don't worry. You and that V-whatever of yours won't ever find the time to cry. 'Cause in five minutes' time, you're gonna be dead."


 * (About Renji Abarai) "What a moron. He really was fast asleep... I came here to see what kind of guy had taken out Mask De Masculine, and I found this guy snoring away without a care in the world. I figured it must be some kind of trap, so I monitored him carefully. But he seriously stayed asleep right until morning. Who could've guessed a guy would actually go to sleep right in the middle of enemy territory? Even so, his luck's run out now. This is the first time I've ever "observed" an enemy for this long. You're finished, Red Monkey."
