Shadowhunter

Shadowhunters (影の子 (シャドウハンター), Shadouhantā lit. Children of Shadow), also known as "The Children of Raziel" (ラジエルの子供たち, Rajieru no Kodomo-tachi), are a subspecies of Humans that are granted supernaturally-enhanced physical abilities that are on par with higher-ranked Supernaturals. The Shadowhunters are considered as the "mediator" between the Humans and the Supernaturals in the Shadowverse mythology and as such have the "task" of protecting both worlds from the threats arised from either the Supernaturals ("Otherworlders") or Humans themselves.

Biology
Shadowhunters, true to its original species, are indistinguishable from normal Humans as they share the same biological characteristics from them. The one thing differentiated from them is their enhanced physical attributes that are considered on par with physically strong Supernaturals. According to several Vampires, their blood are known to be similar to that of an Angel however it doesn't classify them as a Nephilim as their blood are still safe to be consumed by Vampires, Demons and similar creatures unlike Angel or Nephilim's whose blood are considered to be dangerous for them.

While they all in all similar to normal humans, Shadowhunters can still be identified through their Voyance Rune, which appears when a Shadowhunter is born and serves as their "birthmark" in a way. They can also be distinguished with their physical appearance, such as uncommon eye colors (e.g. Oskar's purple eyes and Taiga's indigo eyes), hair colors, physical marks, etc. although these are uncommon.

Trivia

 * The Shadowhunters take inspirations and are loosely based on the titular race from the popular book series The Mortal Instruments written by Cassandra Lee.
 * The names of the Shadowhunter Clan's designated mark are all named after the 22 Major Arcanas of the Tarot of Marseilles deck. The designs of each clan's Voyance Runes are also similar to the Crests from Fire Emblem Three Houses, which in turn also bear similarities to the Major Arcana.
 * With the exception of Thanatos, Helel, Lucifer, Izanagi, and Satanel Clans, all the Shadowhunters' Clans are named after the Ultimate Personas of all Confidant Arcanas from the RPG game, Persona 5/Royal. Helel is the Hebrew name of Lucifer and designated as XVII (Star Arcana), Lucifer's designated Arcana in 5/Royal while he was a previous Ultimate Persona of the Judgment Arcana (designated XX) from the previous series. Thanatos, Izanagi and Satanael are all named after iconic Personas from their designated Arcanas (although in Izanagi's case it was his ultimate form, Izanagi-no-Okami).
