Gusta, the reincarnated form of the mythical Ceris Voldigoad, is the father of the reincarnated Anos Voldigoad. Originally named Gusta Raizeo, he changed his family name to Voldigoad upon moving to the demon realm of Dilhade, seeking better assimilation and honoring his son's identity.

He possesses a solid frame reflecting his trade, with brown hair cropped to his ears, distinctive purple eyes, and a small scar over his right eye. Gusta co-owns and operates the blacksmith shop "Wind of the Sun" alongside his wife Izabella, where he forges weapons and she handles appraisals.

Kind, compassionate, and deeply devoted to his family, Gusta prioritizes their safety, evidenced by protecting Izabella from magic-wielding assailants. His support for Anos led him to advocate relocating their household to Dilhade. He frequently misinterprets situations, especially Anos's interactions with female visitors, assuming romantic intentions that trigger tearful emotional reactions. Anos characterizes him as somewhat foolish yet sincere.

In his youth, Gusta adopted the grandiose alias "Gardelahypt, the King of the Oblivion Sword," later understood as subconscious echoes of his past life as Ceris. Though carrying demon ancestry, his dominant human lineage classifies him biologically as human. His notable blacksmithing skill is demonstrated by fashioning an exceptionally durable adamantine sword for Anos's use in the Demon Sword Tournament.

Within the family, Gusta shares a warm bond with Anos, though his actions sometimes cause embarrassment. He and Izabella often misunderstand situations in tandem, reflecting their similar personalities. His reincarnation intrinsically binds him to Anos's legacy across lifetimes.
