Musical Note Disease Music constantly plays inside the head, and notes become visible and audible from various places. The patient cannot converse or understand others unless they turn their words into song lyrics. Treatment: Directly transmit words to the brain to trigger a response.

Dark Freeze Disease Affects cheerful people due to excessive stress. They can only survive in bright places; while blinking is fine, their body stops moving in the dark, and exposure to moonlight causes them to freeze to death. This disease is hereditary. Fearing the moonlight, they spend their nights in locked, brightly lit rooms and sleep during the day due to their fear of the dark night. Treatment: Unknown

Machine Disease A condition where the entire body turns into a machine. As it progresses, emotions vanish and the patient stops speaking, though some retain the ability to talk.

Despite the mechanization, the heart remains the power source, so they have a normal human lifespan, though rare cases of living for centuries have been reported. Treatment: Unknown

Comet Disease Upon onset, the tips of the hair glow with a faint white light. Most patients have long hair; if the hair is cut short before realizing they have the disease, it becomes untreatable. When the hair grows long enough for the glowing tips to touch the ground, the body is consumed by a flame of light, and that rising light eventually becomes a shooting star that colors the night sky. Treatment: Watch a meteor shower with a precious person.

Cherry Blossom Disease A disease where cherry blossoms bloom on part of the body. Once the petals fall, the patient can no longer be recognized by those around them (becoming invisible), and even their belongings become imperceptible.

Treatment: Make over 100 people smile while the blossoms are in bloom.

Jewel Disease A disease that consumes the body using the heart and brain as nutrients. When the patient dies, the body dissolves into water and the heart turns into a gemstone. There is no pain, so many do not notice even in the terminal stage, often not even realizing they have died. The lack of pain is the only mercy. Treatment: Unknown

Tearstone Disease A disease where bodily fluids such as tears and blood crystallize. It is named so because most patients only show symptoms in their tears. Pain may or may not accompany the shedding of tears, which is said to be related to Mohs hardness. Since tearstones can be precious gems and trade at high prices, patients are warned to be cautious of kidnapping and other crimes. Treatment: Find something truly precious to oneself.
