However, he is easily confused and unnerved by things which he does not understand. As the first Quincy to have a Schrift granted to him by Yhwach, Lille considers himself Yhwach's best creation and the man closest to God to this end, he believes that he cannot be killed by a Shinigami's Bankai. Lille was the first Quincy to ever be bestowed a Schrift by Yhwach. At some point he was also made the leader of the Schutzstaffel. By Lille's claim, however, he was the last Quincy to be bestowed power by Yhwach, which made him the self-proclaimed best creation of the Quincy emperor. When Senjumaru Shutara kills Nianzol Weizol, Yhwach summons Lille alongside his three other Schutzstaffel to fight the Royal Guard for him. When Senjumaru summons a massive guard to fight the Sternritter, Lille informs Senjumaru that Pernida Parnkgjas is saying its size does not matter. After Pernida takes out the guard with The Compulsory, Lille tells a shocked Senjumaru that she likely thought for a moment that the Royal Guard will lose and explains how those on the losing side of battle tend to comprehend and react slower than those on the winning side. Taking out his rifle, Lille proclaims that the Soul King Palace was doomed as soon as Yhwach arrived before seemingly shooting Senjumaru in the head As Senjumaru falls to the ground, Gerard Valkyrie berates Lille for leaving her body in Yhwach's path, prompting Lille to have Pernida remove it. When Gerard expresses disbelief at someone so weak being in the Royal Guard, Lille points out that no one has ever stood against them before taking aim and firing Heilig Pfeil at the cities surrounding the main palace, causing them to crumble from the impact. Lille turns to Yhwach and asks him to pass, only to be surprised when the area around them turns into strips of fabric and disappears. As Lille demands to know what is happening, the real Senjumaru appears behind him and reveals that this was a fake palace created for their arrival before pointing out the real palace, which was hidden by Ichibē Hyōsube. Lille takes aim at the real palace and fires another Heilig Pfeil, only for it to be blocked by a large tree, shocking him.
Soon afterward, Lille is resurrected through the power of Yhwach's Auswählen. After shooting Nimaiya twice through the shoulder, Lille corrects Nimaiya's theories on his power by revealing that he is merely using the power he had not had the chance to use before instead of using a new power. Firing another shot, Lille explains the all-piercing nature of The X-Axis to Hikifune and Tenjirō Kirinji after they attempt to block it as they see Nimaiya has been shot through the chest. Lille asks Hikifune and Kirinji to line up in a straight line so he can kill them with one shot. Later, after Yhwach kills the Soul King and Ichigo Kurosaki and his friends arrive to confront him, Lille shows up alongside the other Schutzstaffel to stop them. When Uryū Ishida sends Ichigo flying off the palace and fires another arrow after him, Lille turns to Uryū, who notes that Lille intends to tell him that killing Ichigo and his friends before throwing them off the palace would have been more practical for protecting Yhwach. After Yhwach absorbs Mimihagi, Lille notices him staggering and voices his concern, only to be shocked when Yhwach dissolves into a multitude of one-eyed black creatures that swarm him and the other Schutzstaffel. The X-Axis, Piercing Everything: Lille's rifle can pierce anything he fires at with perfect accuracy. When Lille fires, the rifle does not release a bullet; rather, it simply pierces everything between the muzzle and the target, leaving its power unable to be blocked by any barriers as a result. When Lille has both of his eyes open, he can fully use The X-Axis, which allows his rifle to pierce through whatever he shoots and renders his body intangible. Though the power will only work for a short period of time when Lille's life is in danger during battle, if he opens his eyes a total of three times in a row during a battle, Lille is permitted to keep them open for the entire battle. Expert Marksman: Lille is a skilled marksman with his rifle, able to aim directly for his targets' vital spots from a distance while firing rapidly and even snipe down the faraway cities surrounding the Soul King Palace. Lille possesses considerable reaction speed. During his battle with Shunsui Kyōraku, when the latter attempted to attack him from below with a shadow blade via Kageoni, Lille immediately leaped into the air in order to avoid it, something which Shunsui himself noted made Lille the first opponent he had ever faced to dodge such an attack on the first try. 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. Diagramm, Diaguramu; German for "Diagram"; Viz Diagramm: Lille's favored weapon manifests in the form of a large black rifle that he carries on his back underneath his cloak. Its forestock is mostly covered in light brown fur, except for a section on the underside near the end of the forestock. The end of the long barrel has a black, plus-shaped extension on it, and the stock is composed of two long, triangular protrusions that stabilize the rifle against Lille's shoulder and torso. If part of the forestock is cut off or destroyed by an enemy attack, Lille can reform it with the appearance of black metal instead of light brown fur. Heilig Pfeil, Hairihhi Pufairu; German for "Holy Arrow", Japanese for "Sacred Destruction Arrows"): Lille can fire bullet-shaped Heilig Pfeil from his rifle. They are powerful enough to destroy the cities surrounding the Soul King Palace with a single shot each.[48] Kirio Hikifune notes that they possess such power due to being composed of highly compressed Reishi. However, they can still be split and deflected if cut by a sufficiently sharp blade.
