Sōgyoku persists as a recurring antagonist weaving through multiple installments of the franchise, maneuvering as a cunning strategist for shifting antagonistic factions. First emerging in Season 1, Episode 41, he resurfaces in Season 2, Episode 11, opportunistically aligning with leaders like Kairen, Kirin, the Valhallan, and the Teoti, only to abandon each when their power wanes, swiftly seeking new alliances to ensure his survival.

His personality blends mischievous cunning with self-serving cowardice, consistently prioritizing self-preservation above loyalty. Though capable of villainy, he avoids prolonged confrontations, retreating the moment the tide turns against him. His fractured relationships include a past partnership with Torame, severed after their faction’s collapse, and tactical collaborations with Nahane during crises involving extraterrestrial threats. Later arcs see him forging a pragmatic alliance with Astrea, perpetuating his cycle of transient allegiances tied to survival.

As the sole Kitoralsus member retaining an antagonistic role across all anime installments, his endurance underscores an uncanny adaptability, outlasting every fallen superior. While his presence remains confined to the anime series, with no expansion into films, OVAs, or spin-offs, the narrative omits specifics about his origins or deeper motivations.
