is a Rank S Drain-attribute Classic Yo-kai of the Shady Tribe.

Biology
Yagyou is a fair-sized humanoid Yo-kai with clay-colored skin, a visible pointy ear and a sole visible sharp teal right eye, with the left one covered by an eye-patch. He has magenta-colored hair with two black horns sticking out, and a cloudy-looking scarf, teal in color. Behind the scarf, there is no neck. He wears a samurai-like attire with long clay-brown sleeves and a darker brown-colored layer of clothing above, as well as two-teeth geta sandals with white tabi. He carries a fairly big golden curved sword with a green handle.

In Yo-kai Watch 3, during the first "ENMA NOTE" quest, Yagyou displays several distinct traits: when confronting Lord Enma and Nate flanked by a Frostail and an Eyellure. He shows little respect for the Yo-kai sovereign; before reading the Enma Note in an attempt to catch Lord Emna off-guard, exhibits an excitement bordering in sadism, while his only visible eye glows red; finally, after being outsmarted due to not knowing an specific rule about the notebook, he quickly loses his temper and charges at Nate and his friends. Even after being defeated and being sent to Infinite Inferno by Lord Enma, he shows a notable soreness in her face.

Yagyou can detach his head from her body- as he has no neck- and shows a notable expertise in swordsmanship.

Origin
Yagyou is based in Yagyu Juubei Mitsuyoshi (柳生 十兵衞 三厳), one of the most famous samurai figures in Japan's feudal era. He was often depicted using only one eye as the other is covered in an eyepatch, similar to Yagyou.

Folklore-wise, Yagyou is based on both the, a type of Rokurokubi (Lady Longnek) that instead have no neck and the heads can move independently from the body at night, and , a cycloptid youkai resembling an oni that hails from the Tokushima prefecture. He appears on a headless horse on very specific dates. Those who encounter this youkai on these nights experience getting bodily thrown aside or getting hit by his steed. To avoid this, one should put sandals on your head and lie down on the ground.
