Shadow

Shadow (影, Kage) are mysterious creatures that inhabit Hitogashima. Their goal is to revive their "Mother", Heine.

Appearance
Shadow's can take the appearance of any human once they scan him. When not copying a human, they can take a humanoid shadow form. When facing a shadow human, their true form is the flat shadow on the ground.

Personality
They dislike being stepped on, so they will avoid anything that tries to step on them.

Power & Abilities
The shadows can copy scan and copy any humans along with his memories, allowing them to perfectly replace them. Their true form is the flat shadow on the ground, while the human is just a collected flesh, which can't be killed and can be regenerated. The true form is vulnerable by physical objects and can be killed by normal weapons. To scan a full human requires more energy. And once they create the flash, the shadows are unable to move for a few seconds, leaving them vulnerable for attacks. If the flat shadow is pierced three times at the same time, the shadow becomes unable to move both her true form and 3D flesh body.

Hizuru's sister hypothesis, the Shadows scan humans with light and absorb their information. The shadows survive by eating human data, however, the data of taste requires them to consume the subject directly, which action leaves black stains behind.

Some shadows only appeared during certain loops due to unique actions.
