Hel

Hel stands as the most formidable and dangerous figure within the shadowy organization SPES, her true nature concealed beneath the surface of protagonist Nagisa Natsunagi's consciousness as a dormant second personality. Bound by absolute loyalty to her originator known as the 'Seed', she ruthlessly claimed the heart of the legendary detective Siesta, an act that inadvertently allowed Siesta's consciousness to linger within the host body. As the pivotal antagonist bridging the protagonist's buried past and the mystery surrounding Siesta's death, Hel remains inseparable from the story's deepest unresolved truths.
