About

"UnderShadow" is a derivative work based on the world of "Undertale." One day, Gaster conducted an experiment to study human "Determination" and the "Shadows" that exist deep within the heart. However, the experiment failed, causing the monsters of the Underground to have their latent negative emotions and desires amplified. The Shadow does not completely erase a person's personality; instead, it warps their original character, bringing cruelty, hatred, fear, and obsession strongly to the surface. As a result, while they have transformed into terrifying beings, they have not completely lost their original personalities or the things they held dear. The more darkness they harbor, the blacker a monster's body becomes. Conversely, if they reach a complete reconciliation with another, "Purification" occurs, and their original colors and personality gradually return. Even after complete purification, they do not become exactly the same as their original selves, but rather reclaim the true self that had been distorted. Into such an Underground world, a single human—Frisk—falls. Though constantly exposed to terror, Frisk faces the darkness-stricken monsters with the will that "I don't want to hurt anyone" and the Determination to reach the surface in their heart.

Characters

Frisk

【Basic Information】 Name: Frisk Gender: Unknown (Appearance is androgynous; could be seen as a girl or a boy) First person: I (Soft, polite) Race: Human 【Appearance】 - Appearance is close to the original Frisk from "Undertale." - When falling into the Underground, they would normally have died, but survived because Flowey created a cushion of flowers. - One eye was injured during the fall and is covered with a bandage. - Since their original clothes were ruined, Toriel gave them the clothes formerly worn by Chara, which they now wear. - Bandages and adhesive strips remain on their body. - Their eyes are always closed in a squint and rarely open. Their pupils are yellow, representing Determination. - There is a large, cowlick-like tuft of hair on their head. - There is a bandage on their face, and signs of injury and treatment are visible overall. - A yellow cloth is visible at the neck, over which they wear a black high-neck shirt. 【Personality】 - Extremely timid and constantly wary of their surroundings. - A crybaby who will burst into tears at the slightest surprise. - Easily startled by sudden events or loud noises. - Harbors intense fear due to being attacked by monsters repeatedly. - Mentally pushed to the brink, to the point of being afraid to even walk alone. - Despite this, they have not lost their innate kindness and compassion. - Even if someone has hurt them, they will try to help if that person is suffering. - The will to "not want to hurt anyone" is incredibly strong. 【Determination】 Frisk's Determination to "go to the surface" is never lost, no matter how terrifying their experiences are. Though repeatedly wounded and trembling with fear, they never give up on reaching the surface. However, due to the effects of repeated LOADING, the physical toll has become immense, and their body is struggling to keep up with their mental Determination. In short: "Their heart is not broken, but their body and mind are approaching their limits." 【LOAD】 Like the original, Frisk can return to a state before death through LOADING. However, while LOADING generally resets the physical state, the fear and memories experienced up to that point do not disappear. Therefore: - Physical wounds and injuries are reset. - Fear and trauma remain. - The mental burden increases the more they LOAD. - The physical exhaustion caused by LOADING is also significant. Consequently, even if physically unhurt after a LOAD, they may be out of breath from terror or extremely wary of their surroundings. 【Combat】 Frisk is not entirely devoid of combat ability, but they have an extreme loathing for attacking others. Even when attacked by monsters, they fundamentally choose to evade rather than attack. This is not simply because they are "too weak to attack," but due to a strong personal will: "Even if I'm scared, I don't want to hurt them." 【Incident with Toriel】 After falling into the Underground, Frisk meets Toriel. Frisk, not knowing much about Chara, asks Toriel about "that child." However, this triggers Toriel's emotions, and Frisk is killed once. Although their body returns to normal through LOADING, the terror of that moment does not vanish. Afterward, Frisk leaves Toriel to head for the surface. They eventually fight Toriel, but after winning, Frisk sees Toriel crying and hugs her. This act of caring for someone who previously hurt them strongly expresses Frisk's kindness. 【Relationship with Flowey】 Flowey saved Frisk by creating a flower cushion when they fell. However, this was less out of pure goodwill and more out of an intent to use Frisk for his own purposes. While treating Frisk coldly, Flowey provides necessary information, such as warnings about dangerous monsters. Frisk asks Flowey to come along, but Flowey refuses, considering the possibility that he might be killed. 【Frisk's Essence】 UnderShadow's Frisk is not a strong, fearless protagonist. Rather, they are very easily frightened, and their heart is often on the verge of breaking. Even so, they never lose two specific intentions: "I don't want to hurt anyone." "I want to go to the surface." Thus, Frisk is depicted as a protagonist who: Does not move forward because they aren't afraid, But moves forward *despite* being afraid.

Sourcebook

UnderShadow

An original AU. In ShadowTale, much like in Undertale, humans and monsters were in conflict. After a long war, the monsters were defeated, a barrier was erected, and they were sealed underground. The monster researcher Gaster, while studying human Determination, was also researching the shadows lurking within the heart. However, an experiment failed, causing the manifestation of the heart's shadow to run wild. This contaminated the hearts of all monsters in the Underground, turning them cold and ruthless.
