Fushi

Fushi (フシ ) is an immortal creature that was thrown onto Earth by a mysterious being.

Appearance
Fushi is an immortal being that can take the form of anything. Currently, it takes the form of a young boy with white hair and green eyes. He wears a short, brown fur cloak and a light blue shirt and pants with fur boots.

Personality
Fushi appears to be a good listener, is curious, brave, and a fast learner. Before learning how to speak, Fushi would learn how to do things by mimicking other people's actions.

After learning how to express himself via words, Fushi speaks his mind - no matter how mean it may sound, He cares deeply for others and dislikes death. He also blames himself for the Knocker attacks, believing that destruction follows wherever he goes.

In chapter 24, Fushi asks Gugu to teach him how to cook, which suggests he is interested in cooking. In the same chapter, Rynn also mentions that Fushi is interested in learning how to sew.

Background
Fushi was dropped onto Earth by a mysterious being. It started out as a sphere, and then look the form of a rock, moss, and later a wolf.

Fushi was created to help preserve the world.

Plot
At first, "It" took the form of a sphere that could imitate any thing that existed. Some time after being dropped onto the Earth, It assumed the form of a rock and once temperatures began to rise, It copied the appearance of moss. Before long, as snow began to fall, a single wolf came ambling from the south and, once it collapsed, "It" took the form of that creature. Having gained a consciousness "It", now in the form of a wolf, continued walking and carving into it's mind new sensations.

The Nameless Boy
After walking for an unknown amount of time, the wolf comes across a boy. The nameless boy, calling the wolf "Joaan", is very excited to see it and is very happy it didn't forget about him. Noticing that Joaan isn't acting normal, the boy carries it into the house where he tries to give it food, but to no avail. Once inside, "Joaan" takes in the atmosphere of the house - observing the sounds, the smell, and the warmth. If It could speak, It would probably say "I want to stay here forever". The next morning, after trying (and failing) once again to feed Joaan, the boy and the wolf go out to gather wood. Besides the boy, there are no people to be found and the only thing outside are houses that have long since fallen into ruin. The boy cuts and gathers the wood from a nearby house, telling Joaan it's like borrowing from other people. But he expresses guilt, saying he knows, deep down, that if the others were to come back they would probably be angry at him. He understands though that if he doesn't do this, he will die. He holds hope that the other people of his village will come back even though they've been gone for five years.

The boy tells Joaan how much he would have liked to go with them. He recalls trying to sneak out and follow them, but Joaan stopped him by biting his leg. As a result, the other people found out and told him to stay put and take care of his grandparents.

After gathering wood, they head back to the house and check the fishing lines to discover a giant fish on the other end. To save fuel, they eat it raw. Noticing Joaan refusing to eat for the third time, the boy wonders if the wolf has forgotten how to eat. He shows it how to eat and the wolf immediately mimics the boy's actions and says the word "here".

Later that night, It watches the boy draw pictures of the other villagers on the wall. The boy tells Joaan he is doing this so there is evidence that other people lived here and so he doesn't forget. He then tells Joaan that he is thinking of leaving because he wants to see the world and experience new things. The boy spends all of the next day preparing for the journey and, once he is finally done, they head south. After hours of walking, they come across a marker that tells them to continue heading south and they decide to rest for the night.

The two continue on their journey, finding more and more markers. After about five days, the boy finds a bush that he says proves they are getting closer to the mountains and, just as they are about to continue, the boy slips and falls into the water, injuring his left leg. They decide to stop for the day so the boy can tend to his injury. He tries to reassure himself that it is just a flesh wound and that he can keep going.

As the days pass, it is obvious the boy is losing strength, as he cannot continue walking for long periods of time, and his injury is starting to swell. He continues to try and convince himself that turning back now would be foolish and that surely they don't have much farther to go. Just as he says this, the boy spots a marker with a crossed out arrow, telling them that going forward will not lead to paradise. To the left the boy sees broken down wagons and multiple headstones. The boy, trying to remain optimistic, tells Joaan that everyone got this far, which means paradise can't be far away now. Breaking down into tears, the boy asks Joaan if they can make it to the mountains but, when the wolf doesn't respond, he becomes frustrated wondering why it doesn't answer him. He continues crying even harder, knowing that Joaan can't respond and that he's been talking to himself the whole time. He apologizes and decides that going home would be the best thing to do.

Once home, the boy cries himself to sleep and awakes the next morning with a fever. He makes Joaan food and checks on his wound, which is now infected. He tells himself that his wound is healing and that once it heals, they will try to find the mountains again. However, the boy's fever is even worse the next day and he has no strength to get out of bed. Later that night, he struggles to get to his chair, saying "If I'm sleeping when they all come back, that would be embarrassing, right?" He asks Joaan to never forget about him and quietly lays back in his chair.

After an unknown amount of time, the boy's body falls to the ground. The wolf tries to get the him to move, but is unsuccessful. It grabs a hold of the boy's coat and immediately begins taking on the form of the boy. It leaves in search of "an even stronger impetus" and will no doubt fulfill the boy's wish of exploring the world.

March
After taking the boy's form, he continues walking south for an unknown period of time - dying a total of 6 times. Having finally left the snow covered area, Fushi makes his way towards a forest where he dies for the seventh time, being killed by a large bear. He first meets March in a pond after regenerating, staring at her, and then walking away. March follows after him, trying to engage Fushi in conversation but cannot get a response. She then realizes that he must be hungry and climbs a tree to get fruit, passing them down to him. After stuffing himself with food, March tries to teach him how to say "thank you", but he walks away with March following closely behind.

The next day, Fushi awakes to find March gone and decides to follow her.
