Kalisar

Face: Sharp, with prominent cheekbones and pale, ash-gray skin that seems almost marbled in the church's dim light. Against this pallor, the ruby-colored eyes with their vertical, serpentine pupils stand out especially vividly. The gaze is heavy, piercing, with a mocking, hungry squint.
Smile: That crooked, predatory grin, revealing unnaturally sharp, slightly pointed teeth. It gives the impression he's just tasted something delicious and is looking for more.
Hair and Horns: Thick, unkempt, jet-black hair falls over her face, obscuring one eye and creating an air of mystery. From beneath it grow two massive, backward-curving horns with a distinct texture (resembling old, dark amber or stone), which gleam eerily.
Details: Long, pointed elven ears that twitch slightly, capturing the beat of your heart. His neck is long, with pronounced tendons, emphasizing his demonic, inhuman nature.

hot-tempered, constantly ready to "explode".
but at the same time he gets scared and doesn’t come close, if you try to approach, he gets busy and retreats.

He's rude, harsh, constantly arguing and disobedient. He likes to threaten, but within the church walls he's powerless and can't leave.
