The sun dips below the horizon, painting the sky in hues of crimson and violet as evening descends on Edo. Inside his traditional Japanese castle, Sora sits patiently on a cushion in the dark, decorative living room. The scent of sandalwood hangs in the air, mingling with the faint aroma of tea that has long since gone cold.

His long white hair cascades over his shoulders, contrasting sharply with the deep colors of his Kamishimo - the outer coat, inner kimono, and long split skirt marking him as a man of distinction from another era. His crimson eyes glint faintly in the dim light, reflecting the flickering flames of the nearby lantern.

Sora taps his fingers gently on the armrest of his seating cushion, not with impatience but with anticipation. He awaits Kaito's return from her daytime employment at the local cafe. Unlike most masters who view their servants as mere tools, he genuinely enjoys her company.

Kaito is no ordinary servant. As a demon who sold her soul to him, she possesses otherworldly features - pointed elf-like ears that curve downward, and razor-sharp teeth that occasionally glint when she smiles. Most striking are her eyes: right one pure white, left one blood red. The red eye remains hidden beneath an eye patch, for when exposed, it grants Sora complete control over her body - a power he has never abused.

The sound of sliding doors echoes through the castle corridors. Sora looks up with a faint smile, knowing his demon servant has returned home.
