Äs Nödt

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

Appearance
Äs has long, dark hair and dark eyes with visibly light pupils. Its attire is a variation of the Sternritter's typical white uniform, consisting of the order's signature hooded cloak, an ankle-length trench coat with many buttons on its front and sleeves, and black boots. Äs also has black fingerless gloves with spikes on the wrists and wears a dark mask, which obscures the lower half of its face and features five spikes running down its center. It has dark fingernails.

Personality
Äs believes irrational fear is a force which one cannot overcome, unlike rational fear. Because of this, it has the utmost confidence in its special ability. It is not above chastising its own allies, such as when it chided Mask De Masculine for not stealing 6th Division Lieutenant Renji Abarai's Bankai when he had the chance. Äs is quite arrogant, declaring that the stolen Senbonzakura was "its" and had grown attached to it, stated it felt lonely without it. Äs also relishes the opportunity to fight Byakuya Kuchiki, when denied an answer by Rukia of his whereabouts, he sadistically remarked that should it kill her, would the 6th Division Captain arrive, when Rukia suggested he might, it began to maliciously attack her. It also takes delight in its ability to cause Fear in foes, and has a habit of laughing menacingly

The Thousand-Year Blood War arc
Upon receiving the orders of Yhwach, Äs 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, Äs and the other Sternritter create pillars of blue flames prior to engaging the Shinigami in battle. Indiscriminately massacring numerous lower-ranking Shinigami, who are unable to injure it, Äs is intercepted by 6th Division Lieutenant Renji Abarai. While Äs effortlessly blocks Renji's strikes with its bare hands, they are interrupted by the arrival of Mask De Masculine and 6th Division Captain Byakuya Kuchiki. When Äs' hand is severely cut by Byakuya, Mask berates it for allowing its Blut to be broken so easily. After Äs' comrade is neutralized, Byakuya activates his Bankai, Senbonzakura Kageyoshi, only for it to be stolen by Äs' medallion.

Wounding Byakuya in the ensuing battle, Äs asks Byakuya if he is aware how, rather than being poisoned, he has been infected by fear. Commending Byakuya's resilience in not dying instantly like most of its victims do, Äs explains the fear-inducing ability of its Spirit Weapon, which causes victims to doubt everything and lose control of all rational thought. After receiving a blow to the chest, an uninjured Äs declares Byakuya's heart is already stricken by fear towards it despite Byakuya's remarkable willpower. Striking the motionless captain, Äs describes how, unlike fear which comes from reason, true fear is instinctive, and so cannot be escaped. Evading Byakuya's subsequent assault, Äs attacks with the stolen Senbonzakura Kageyoshi, causing Byakuya to fall amid a torrent of blood.

As Byakuya lies heavily injured, Äs tells him it was obvious he could not win against his Bankai with only his Shikai. When Renji attempts an ambush from behind, Äs negates the strike with Blut Vene. Moving to attack as well, Byakuya is overwhelmed by the blades of Senbonzakura Kageyoshi and is smashed into a wall, grievously wounding him. When Mask prevents an enraged Renji from activating his Bankai by attacking him, Äs chastises Mask for not waiting, for they could have stolen it as well. When Mask is surprised by this, Äs tells him he should go home and review the Daten which Yhwach had provided.

When Captain-Commander Genryūsai Shigekuni Yamamoto confronts Yhwach, Äs, NaNaNa Najahkoop, and Bazz-B ambush him from above. Before they can attack, Yamamoto scorches them with Ryūjin Jakka. Later, Äs, having survived this attack, is present when Yhwach names Uryū Ishida as his successor, which shocks it.

During the Wandenreich's second invasion of Soul Society, Äs notices the stolen Bankai being taken back by the Shinigami and the apparent defeat of Cang Du and BG9. In the morning following Rukia Kuchiki's return to Soul Society, Äs confronts her, stating how lonely it is without Senbonzakura. Explaining that it is aware of who she is, it asks for the location of her brother. When she refuses to answer, it asks if he would arrive if it killed her, and then proceeds to attack. In spite of Rukia's attempt to block its thorn with ice, Äs manages to infect her with its fear. Äs gloats at her attempt to protect herself, but reacts with confusion when an unaffected Rukia asks what it is afraid of.

Equipment
Medallion: Äs possesses a round device which is roughly the size of a person's palm and has the Wandenreich insignia etched onto its surface. When activated, the device can steal a currently released Bankai in the immediate vicinity, as evidenced when Äs used it to take 6th Division Captain Byakuya Kuchiki's Senbonzakura Kageyoshi. The medallion's owner can use the stolen Bankai's power at will. Since Hollow powers are poisonous to Quincy, the stolen Bankai were returned to their original Shinigami owners when the Bankai were Hollowfied by the Shin'eiyaku. Being in possession of a Bankai prevented Äs from activating Quincy: Vollständig.

Powers & Abilities
Great Spiritual Power: Äs' spiritual power is on a level comparable to or greater than that of a captain-level Shinigami, proven when Äs swiftly defeated 6th Division Captain Byakuya Kuchiki.

Enhanced Strength: Äs possesses great physical strength. It blocked several attacks from 6th Division Lieutenant Renji Abarai's Zabimaru with just its Blut Vene-enhanced arm and impaled Byakuya with its hand.

Fear Inducement: Despite the considerable attack strength of Äs' spirit weapon, the true power of the thorns lies not in their offensive capability, but instead in their ability to induce limitless fear in those who are struck. Just a single wound is enough to inspire a deep-seated fear towards Äs, causing victims to doubt everything, lose control of all rational thought, and see visions of their deepest fears. While this would typically result in instantaneous death due to a person's heart being unable to bear such intense shock, an individual's experience and willpower can be used to resist this fear to an extent, though Äs is confident all would succumb to it eventually. When the thorns strike an object a black substance of fear begins to spread. It can even move through the objects to induce fear in a foe.

Reishi Absorption: As a Quincy, Äs can absorb spiritual energy from the atmosphere, combining it with its own spiritual energy to form weapons and use different techniques.


 * An advanced Quincy technique which grants one inhuman defensive and offensive capabilities by making Reishi flow into the user's blood vessels.


 * While Äs' defensive form of Blut is strong enough to negate attacks from Renji's Shikai, it is not absolute, and can be torn using sufficient power, as evidenced when Byakuya's Senbonzakura managed to cut Äs' hand.

Spirit Weapon
Reishi Thorns: Using its abilities as a Quincy, Äs can concentrate both spirit energy and particles in order to transform them into weapons. Its favored weapon manifests in the form of several luminous thorns floating in close proximity to its person, which are used to viciously impale victims and can pierce the body of a captain-class Shinigami with ease. The thorns can be fired similarly to darts at high speed accurately

Quotes

 * (To Byakuya Kuchiki) "Fear can be overcome through experience. Those who know battle often come to believe this. 'Fear that comes from reason' is kind. It can be conquered through force of will or through experience. It is possible to suppress such reasoned fear by severing it at its source. But true fear is without reason. It is not an emotion, but an instinct. True fear occurs without reason, without bounds. It is like a swarm of insects crawling up the body. We cannot escape from our instincts."
