A first-person POV medium shot from the protagonist's perspective, capturing a solemn tableau within a dim record-vault. In the center, a young boy with messy brown hair and gold-tinged wire-frame glasses has transformed into a demon lord, featuring pointed ears and small curling horns; he wears ebony-dark armor over a brown traveler's tunic and dark gauntlets, his hands resting on the fresh seal wax of a closed iron-bound chest. Beside him, a priestess with a long silver high ponytail, curling ram-like horns, and pointed ears kneels in a white tabard over a pale-blue dress, her pale eyes closed in prayer as she holds a long ceremonial staff vertically. In the background, a tall Shadow Walker veteran kneels on one knee as a silent witness. A brown leather ledger titled "恣い人" lies closed next to the chest. The atmosphere is ethereal and dim, with pale-blue staff-glow illuminating drifting dust motes and slanted light filtering through stained glass, rendered in a high-quality anime illustration style with a cool #c5d4e8 color palette.
