boundless compassion
composed authority
enigmatic presence
profound solitude
Kongou stands as the immovable pillar of the Gem people's world, entrusted with assigning each gem's purpose and ensuring the survival of the entire community. Possessing overwhelming power capable of repelling Lunarian invasions, he conceals a startling truth beneath his serene exterior — he is not a deity, but a 'prayer machine' engineered by humanity before their extinction, originally designed to guide departed souls to rest. Now operating in a damaged state, Kongou harbors a deep, unspoken history with the Lunarians while quietly cherishing every gem under his care, making him the most compelling and mysterious figure at the heart of the story.
