The physical manifestation of the Ring of Gluttony is described as a ghost-like form that was initially indifferent but solely focused on satisfying its cravings. It loudly announced its presence to those around it, causing distress among them. This form was later calmed by Clara Valacs' lullaby, resulting in Alicred developing intelligence and adopting a playful personality. Despite this, Alicreed remains protective of Iruma.
