Albert Pitt is an apprentice gnome entrusted with maintaining Aqua's gravity to mirror Manhome's levels. Despite his youthful appearance and short stature, he is nineteen years old. He habitually cracks "old guy jokes," which frequently irritate Aika when she is nearby. He wears glasses, though the severity of his vision impairment remains undefined. Like all gnomes, he possesses exceptional night vision cultivated from a life predominantly spent underground.

He suffers fainting spells, especially during Neo-Venezia's summer heat, attributed to gnomes' general intolerance for high temperatures. He resides on Ukijima, where he once cared for Akatsuki and Woody as children. Aika develops a profound crush on him, often growing shy around him. This affection evolves into mutual love, though Aika remains easily flustered when Alice or Akari tease her about their bond. Albert reciprocates her feelings, and they eventually form a romantic relationship.

His background includes upbringing within the gnome community, shaping his expertise in gravity maintenance and adaptation to subterranean life. His apprentice role remains central to his character across official media, with no significant deviations in core duties or development beyond his relationship with Aika.
