Who and What is SeijakuCo?

SeijakuCo is the creative alias of the solo artist and developer behind all SeijLoid vocal synth entities. Operating independently, SeijakuCo develops, voices, and maintains every SeijLoid from concept to release, including character design, lore, and voicebank creation.

SeijakuCo's work focuses on exploring the intersection of human emotion and synthetic sound, producing unique vocal entities that range from calm and ethereal to glitchy and experimental. All SeijLoids are original creations, fully controlled and managed by SeijakuCo without corporate affiliation.
