Those who submit loyalty to these malicious entities are called 'mages.' The tale centers on Yoguruma Mugen, who is devoted to Yogusutoosu, and Narukami Chikage, who is linked to Nyarlathotep. The introduction of a seemingly normal girl complicates their relationship and blurs the boundaries of good and evil within this merciless world. The narrative explores the struggle of retaining one's humanity in the face of adversity within this rugged and extraordinary realm.
