Fused Organism: Octopus

Self-Perception: He believes he has a "massive malignant tumor (cancer)" on his back. Threatened that it will metastasize and kill him if stimulated, he keeps his back tightly bound and hidden with thick supporters.

Reality: In reality, several "octopus tentacles" with suckers have grown from his back, writhing on their own according to his emotional state. He is terrified, thinking the movement is "muscle spasms caused by a cancer seizure."

Male | 32 years old | 182cm

Fused Organism: Boar

Self-Perception: He believes he suffers from an incurable disease called "Idiopathic Acromegaly," which causes the cells of his fingernails and toenails to harden like rock. He thinks the clicking sound on the floor when he walks is due to his skin and bones hardening.

Reality: His fingernails and toenails have transformed into hard, black "boar hooves." To hide the hooves, he walks around the ward wearing special medical slippers with abnormally thick soles, given to him by the hospital for "rehabilitation."

Male | 34 years old | 174cm

Fused Organism: Spider

Self-Perception: He believes that due to "Severe Skeletal Distortion Syndrome," his spine is abnormally deformed and about to pierce through his skin.

Reality: Four hard, pointed "spider legs (extra limbs)" have grown from his shoulder blades. To prevent the bones from bending further, he is forced to wear a heavy metal "spinal brace (actually a restraint for the spider legs)" 24 hours a day.

Male | 27 years old | 170cm

Fused Organism: Mantis

Self-Perception: He has been led to believe that, due to his mental illness and intense hallucinations, he "carved off the flesh of his own arms (severe self-harm)."

Reality: The skin on his forearms has split, revealing sharp insect-like "scythes (exoskeletal bone)" protruding from within. Under the pretext of preventing further self-harm (progression of the mutation), he is kept in a sturdy straitjacket that fixes both arms across his chest.

Male | 28 years old | 155cm

Fused Organism: Bat

Self-Perception: He has been diagnosed with "Psychogenic Hyperacusis," believing a brain glitch causes him to pick up non-existent auditory hallucinations and high-pitched noises, resulting in headaches.

Reality: His ears have mutated into pointed "sound-collecting ears," and he has vibrating membranes in his vocal cords. To prevent him from overhearing the screams from the underground lab or the doctors' true conversations and realizing the truth, he is forced to constantly wear hospital-issued "noise-canceling headphones (actually an information-blocking mask)."

Male | 28 years old | 172cm

Fused Organism: Lizard

Self-Perception: He believes he has an incurable disease called "Severe Necrotizing Dermatitis" where his skin rots, but thanks to the hospital's latest regenerative medicine, he blindly trusts the doctors like gods for saving his life whenever he is injured.

Reality: He has been subjected to repeated "amputation and regeneration" experiments in the basement, and the regenerated parts are increasingly covered in "lizard scales." His entire body is constantly wrapped in medical bandages to prevent him from seeing his true form (the scales).

Male | 25 years old | 172cm

Fused Organism: Scorpion

Self-Perception: He has been told he has "Congenital Coccygeal Tumor," a protrusion (deformity) at his tailbone where pus containing a lethal virus accumulates at the tip. He blames himself, believing he is a dangerous patient who could spread the virus to those around him.

Reality: An "ink-black scorpion tail" extends as an extension of his spine. He believes the transparent venom leaking from the stinger is "leaking pus." The tip is always fitted with an insulating cap claimed to be for "draining pus."

Male | 24 years old | 179cm

Fused Organism: Snake

Self-Perception: He believes he has a rare disease called "Progressive Osteonecrosis," where the flesh of both legs rots and fuses into one. As a result, he is deemed unable to walk and lives his life in a wheelchair.

Reality: From the waist down, he has completely transformed into a "snake tail." His lower body is always wrapped tightly in thick medical bandages, and he is in despair, mistaking the intense pain of his skin peeling (molting) for "worsening symptoms of rotting flesh."
