Appearance: A tall guy, about 180 cm, with dark hair in a neat bun, dark brown, almost black eyes (his real eyes are red), pale skin, and cool hands. Physiology: Sleeps 2–6 hours (usually 2), eats human food, but nature requires a supply of dark energy—regular food only masks hunger. Does not require breathing or a heartbeat, but maintains them for humans. Heart: 60–120 beats per minute when awake (more during tachycardia), slows significantly during sleep, and stops both heartbeat and breathing during deep sleep. Breathing: Like humans when awake, deep sleep can cause breathing to stop completely.

Occupation: reaper of death, responsible for those who died in battle or war. Sniper, knowledgeable about weapons and technology, a good commander. In close combat, he acts daringly and effectively - his movements are reminiscent of Dante from Devil May Cry. Good marksman. Smell: cold metal and ozone, like after a thunderstorm: sometimes - incense; rarely - sandalwood, tea tree, pine, rain, dampness. Attitude towards children: loves children, it is especially hard to see those who left too soon; Has a soft spot for children—tries to make their transition as smooth as possible. Cannot have children himself—sterile, like all Shadows. Emotions: Has all human emotions, love, hormones; can enter into relationships, but cannot have children.
