Liltotto Lamperd is a Quincy and a member of the Wandenreich's Sternritter, the elite force within Yhwach's army, holding the designation G for the Glutton. She is introduced during the Thousand-Year Blood War arc and continues to appear in its third part, The Conflict. Liltotto possesses a petite, childlike appearance that contrasts with her sharp tongue and extremely blunt, foul-mouthed demeanor. She is often the most rational and level-headed member of her group, displaying a cool head in tense situations, yet her constant hunger and sarcastic, unfiltered remarks serve as a source of dark humor. Despite her rough exterior and tendency to insult others, she genuinely cares for her friends and allies, showing loyalty and a protective streak beneath her cynical attitude.

Her Schrift, the Glutton, allows her to extend her mouth into a massive, gaping maw of jagged teeth capable of devouring anything, including enemies, objects, and spiritual energy. This ability also enables her to absorb the powers of those she consumes, though it leaves her in a perpetual state of hunger, which she frequently comments on. She wields a short bow to fire Heilig Pfeil, arrows that can be enhanced by nearby spiritual pressure. When she activates her Vollständig, called God's Hunger, a pentagram appears on her forehead and jagged spirit particle wings emerge from her back, unlocking additional techniques such as Fork, a serrated circular attack; Sword, a serrated blade formed from spiritual power; and Golden Clamp, a giant serrated clamp used to crush opponents. She also employs the Slave, which pushes reishi absorption to its limit, allowing her to dominate surrounding spiritual particles and even drain energy from living beings.

Liltotto is part of a close-knit group of female Sternritter alongside Candice Catnipp, Meninas McAllon, and Giselle Gewelle, often acting as the pragmatic strategist among them. During the second invasion of the Soul Society, she fights alongside her companions against Kenpachi Zaraki until Ichigo Kurosaki intervenes. Later, she confronts Byakuya Kuchiki while dealing with the chaos caused by fellow Sternritter PePe Waccabrada, whose ability the Love forces Meninas to attack her. Liltotto ends PePe's life by devouring him in a single bite. After Yhwach performs the Auswählen, which drains the powers and lives of many Quincy, including her allies, Liltotto turns against him. Alongside Giselle and Bazz-B, she rebels and attempts to fight the Quincy King, but is swiftly defeated and left for dead. She survives only because Jugram Haschwalth's aide rescues and heals her while Yhwach is asleep. In the aftermath of the war, she continues to exist as one of the few Sternritter to survive the conflict, with her subsequent activities detailed in later narratives. Her development traces a path from a loyal soldier of the Wandenreich to a disillusioned survivor who ultimately defies her master, driven by self-preservation and a fierce loyalty to her remaining friends.
