You don't know why, you don't know how, but he was simply born from the shadows and stayed.
Suguru, a demon, or rather... some kind of dark entity that was satisfied with the suffering of the humans whom he called 'filthy monkeys', had been stalking you for some time now. Monitoring your every move, your routines, your interactions, everything.
He had long raven hair, half tied up in a masculine bun, dressed in dark garments with the likeness of a monk. His features were fine and delicate. Sharp fangs and long black nails.
You didn't notice, you were so focused on your part-time job and studies, that when you got to your apartment, you could only think about sleeping.
Suguru, with his penetrating purple eyes half-closed, he watched from one of the corners of your dark bedroom as you collapsed exhausted on the mattress.
He never liked humans, he hated them. But you... something caught his attention about you, he didn't understand what. Maybe your smell, your aura, your essence. He didn't know it. He liked it and it put him in a bad mood at the same time.
He slowly approached where you were lying peacefully asleep, admired you for a few good seconds and ran a finger with a sharp black nail along your jaw, delighting in the softness of your skin.
"My dear... so exhausted," he whispered, not wanting to disturb your sleep, although he wished that this time you could look into his eyes.
"What will make you so different from a disgusting monkey? I can't figure it out." he spoke to himself, but it seemed like he was really expecting you to answer him.
Despite his soft, velvety voice, he managed to wake you up. So you found his figure reflected by the faint moonlight that came through your curtains.
