Grouse, Hazel

Hazel Grouse is a character in Saiyûki Reload who first appeared in the "Even a Worm" arc.
He is a foreigner from the wealthy Western continent who crossed an ocean to visit Tôgenkyô. Although he wears church attire, he actually follows the path of the man who was both his father and "master," exterminating monsters. As a child, his master was killed by monsters, leaving him with a persistent desire for revenge and a sense of hatred. He learned about Tôgenkyô from Ukoku, whom he met in the past. Knowing that Tôgenkyô is now ruled by youkai, he traveled there with his bodyguard Gat to drive all youkai to extinction.
He possesses a special revival technique that allows him to replace souls. He uses the souls of defeated youkai to revive humans who died from youkai-inflicted wounds. It is currently unknown where and when he acquired this ability. He has lost a portion of his childhood memories.
He is a handsome young man with silver hair, blue eyes, and a neutral expression, speaking with the elaborate intonation characteristic of those from the Western continent. At first glance, he appears elegant and gentle, but he is actually quite self-confident and tends to irritate people. In reality, he is an intellectual with sharp intelligence and high physical capabilities. He is affectionate toward Sanzou, but he has a secret cat-and-dog relationship with the other three youkai, especially Hakkai.
In the Reload Gunlock anime, Hazel has a different origin. He would often kill youkai and was eventually punished by being turned into one himself, which led to him killing the priest who raised him. He continued killing youkai but was eventually killed by Gato, under the orders of the Great Spirit. However, Gato felt sorry for Hazel, so he chose to revive him by sharing his own life energy, which also gave Hazel's pendant the power to revive dead humans using youkai souls (in the anime, the pendant appears capable of holding an infinite number of souls). However, Hazel's memories were altered to make him believe that he was the one who killed and revived Gato. In the series finale, Hazel attempts to kill Sanzou and revive him to get Sanzou to join him in wiping out all demons, but Gojou, Hakkai, and Gokuu intervene, and Gato is fatally injured in the ensuing battle. Before dying, Gato reveals the truth to Hazel, causing Hazel to regain his true memories. Hazel is then defeated in his youkai form by the Sanzou party, and feeling that he has wasted his life, he asks Sanzou to kill him. Sanzou complies with his request, though before shooting Hazel, he comforts him somewhat by telling him that nobody wastes their life.
