The Beholder

The Beholder (観察者, Kansatsu-sha) is Fushi's creator and the narrator of To Your Eternity.

Background
Not much is known about this mysterious being, but it has been revealed that he created Fushi to collect information and protect the world. The Beholder also revealed that he is not immortal and will one day die.

Appearance
The Beholder has the appearance of a mannequin with smooth, light-colored skin that seemed unnatural, with no facial hair, eyebrows, or hair. He wore a long, black cloak that seemed to become translucent on the bottom.

After his reincarnation, he takes the appearance of an eleven-year-old boy and looks accordingly: He is a lot shorter than before, his black hair reaches the base of his neck and his bangs are about as long as Fushi's. His face has also changed, as he now has eyebrows and lashes that accentuate his slanted eyes. He wears plain clothes consisting of a pair of shorts and a t-shirt, both of which seem to be a little bit too large for his slim body.

Personality
The Beholder takes a very rational approach to the happenings in the world he watches over. Because of this, he rarely shows emotions or compassion for anyone.

Even after his reincarnation, his mindset doesn't change. While he enjoys the pleasures of being a human, such as eating nice food and taking baths, he doesn't smile or show any other emotion

Abilities
The Beholder has the ability to sense the Nokkers and know where they are (except for when they are underground). He compares it to the feeling of bugs crawling on your skin. "As eggs, you cannot notice them, but once they hatch, you are subject to great unease." The Beholder is also strong enough to control Fushi, as seen in chapter 32, when he forces Fushi to transform from the boys form into a wolf. Although he can control Fushi's body, he cannot control his mind. Several times in the story The Beholder, even as Satoru, seems to have the ability to manipulate bodies and objects, as he has once pulled a sword from his body, and crushed it, while as the beholder, and another time turning a Nokker possessed Funa into a Flower, and then crushing the Nokker that was a inside it, as it tried to escape, giving the flower one of the women at the orphanage.

Trivia

 * Although Fushi is normally the only one that can see and communicate with him, The Beholder seems to be able to show himself/talk to other people as well. This can be seen in chapter 54 when Pioran asks The Beholder to take her and, if possible, let her be reborn into something that can help Fushi.
 * The Beholder hides many things from Fushi, including things about Fushi's abilities (being able to resurrect the dead) and the Nokkerr's whereabouts (ex: He failed to mention to Fushi that the Knocker was in Hisame's arm)
