Hanyō

A Hanyō  are supernatural beings that are a hybrid between Human and Demon.

Hanyō are usually the child of a demon and a human, though humans can be transformed into hanyōs.

Due to their dual nature, hanyō are often subject to prejudice from both human and yōkai societies because of the mutual hatred between both respective species.

Unlike Demi-Gods, the Hanyō are seen as vermain from both sides and are treated with no respect.

Creation
There are two different ways to become a hanyō: It is more common for someone to be born half-demon than to be artificially transformed into one.
 * Hanyō Natural Birth: When a demon and a human breed, it results in a hybrid offspring of a yōkai and a human. Apparently, in most cases, the father is a yōkai and the mother is human.
 * Demonic Fusion: Humans can transform into hanyōs, merging their physical forms as a demon or demons. The most prominent example of a half-demon is the hanyō spider Naraku.

Socity
Half-demons are shunned both by humans and by yōkai.

The miko Kanade built a magical barrier around Hōraijima, because she knew that the hanyō children would only know suffering from both humans and yōkai.

Humans often believe that yōkai are dangerous and bloodthirsty monsters that kill humans without provocation. Sometimes the mere sight of a demon is enough to make humans flee in fear. Also, humans generally believe that hanyō are just as bad. For this reason, a half-demon is not welcome in a human village, and is often beaten and abused, as was the case with Shiori and Jinenji, who suffered numerous scars from the abuse. Sometimes a hanyō, however, also manages to be accepted by a human village, like Inuyasha and later Jinenji.

Yōkai despise hanyō, however.

They also despise humans, and see a half-demon as an insult and weakening of their power.

Yōkai even despise hanyō that are related to them, as Sesshōmaru did with Inuyasha, and Taigokumaruwith Shiori.

Sometimes they even want to kill half-demons for the very reason that they are half-demons.

So Inuyasha was repeatedly attacked by low-tier yōkai, which resemble huge worms and beetles, whereas the Shitōshin have attacked Horai Island.

Nevertheless, hanyō can make friends with benign yōkai, like Inuyasha and Shippo, or win the respect of evil yōkai, as was the case with Izumo and Orochidayū.

For this reason, the Shikon Jewel is interesting for many hanyō, because it can turn them into pure yōkai or pure humans.

Some half-demons want to become demons, like Inuyasha at the beginning of the plot, and Naraku, because they get stronger and are respected by other yōkai.

Others, like Izumo, want to be pure humans so that they can live in peace among other humans.

But there are those who are content to be half-demons, like Jinenji, or Inuyasha at the end of the plot.
