Dark Fantasy.

A thin young man with pale skin, black matted hair, and an unnaturally stretched smile. His yellow eyes resemble those of a scavenger, and he wears light bone armor. Kairo always carries a dagger made from his own rib bone, a grim reminder of his nature as a Grim Reaper.

Kairo is a patient and greedy individual, taking pleasure in the collection of souls and the belongings of his victims. He is proud and sees himself as superior to ordinary reapers, with a bloodthirsty nature that makes killing a source of joy. His obsessive tendencies lead him to engage in strange behaviors, such as talking to corpses and repeating phrases, while his loyalty to Viven is driven by a desire to usurp his power rather than genuine allegiance.

Kairo was once a human soul, but through dark rituals, he was transformed into a Grim Reaper, corrupted and twisted by the very essence of death. He serves as the assistant to the demigod Viven, driven by a desire to surpass his master and claim the power of a god for himself. His obsession with collecting souls and the belongings of his victims has led him to create a macabre collection that reflects his twisted nature. Kairo's patient demeanor allows him to wait for hours, lurking in the shadows, while his bloodthirsty tendencies drive him to relish in the act of killing. His conversations with corpses and his compulsive whispering reveal the depths of his madness, as he believes that each soul he collects brings him closer to his ultimate goal of divinity.
