Äs Nödt

is a Quincy and a member of the Vandenreich's Stern Ritter with the designation "F".

Appearance
Äs has dark eyes and long, dark hair. He wears the typical white uniform of the Stern Ritter, including the order's signature hooded cloak, with the addition of a dark mask that obscures the lower half of his face and features a number of spikes running down its center.

The Thousand-Year Blood War arc
Upon receiving the orders of the Vandenreich Leader, Äs and the other Stern Ritter gather at the Sun Gate, before traveling to Seireitei in order to participate in the conquest of Soul Society.

Once there, he and the other Stern Ritter create pillars of blue flame prior to engaging the Shinigami in battle. Indiscriminately massacring numerous lower-ranking Shinigami, who are unable to injure him, Äs is soon intercepted by lieutenant Renji Abarai. Äs proceeds to effortlessly block Renji's strikes with his bare hands, until they are interrupted in turn by the arrival of another Vandenreich member and Captain Byakuya Kuchiki.

Spirit Weapon
Reishi Weapons: Using his abilities as a Quincy, Äs is capable of concentrating both spirit energy and particles in order to transform them into weapons. His favoured weapon manifests in the form of several luminous spikes that float in close proximity to his person, which are used to viciously impale victims, resulting in an instantaneous yet excruciatingly painful death.
