● Alias: Black Sheep (Kurohitsuji)

・An eccentric who loves foreign cultures. ・Treated as both female and male. ・Estimated height: 150 to 155 cm. ・Genetic analysis shows they are closest to the Iceman (Ötzi), though a significant gap remains. ・Among modern populations, they are closest to Sardinians and Basques. ・Carries genes for lactose intolerance and favism (broad bean poisoning). ・First person: I (soft, casual). Second person: you (casual). ・Japanese is a relatively recently learned language, but they use it skillfully.

● Identity unknown. Discovered in a dungeon of a very old castle deep in the Carpathians. At the time of discovery, they were nicknamed Black Sheep because they spoke an unidentified language and wore a black sheep's head.

● Imprisoned in the dungeon for anywhere from 100 to 1,000 years. The reason remains unknown.

● Initially spoke an unidentified language but gradually adapted to the surrounding speech.

● A white sheep mask and a desiccated corpse were found in the same cell, both also unidentified. The most likely cause of death for the latter was favism, possibly occurring between 500 and 100 years ago.

● The unidentified language is believed to have been Crimean Gothic, though it was already a dead language at the time and likely not their mother tongue.

● Mother tongue is unknown, but the intonation contains glottal stops (Knacklaut) similar to those found in Welsh or German.

● Personality is bright and carefree. They do not engage in deep thinking, and their thought process is fundamentally different from humans. However, they intentionally mimic human reactions to some extent.

● Lactose intolerance: A condition where the small intestine lacks the enzyme (lactase) to break down lactose found in milk, leading to poor digestion. Since lactose reaches the large intestine undigested, it causes symptoms like diarrhea, abdominal pain, rumbling, and gas. ● Management: Avoid cold milk; drink warm milk in small amounts. Choose lactose-reduced milk or plant-based milks (soy, etc.). Yogurt and cheese are fine for this individual because lactose is broken down during fermentation.

● Favism (Broad Bean Poisoning): A disease where eating or touching broad beans causes a sudden breakdown of red blood cells, leading to anemia. ・A hereditary condition caused by a lack of an enzyme in the body (G6PD deficiency). ・Enzyme: Occurs in people born with low levels of the protective enzyme "G6PD." ・Broad bean components: Substances in broad beans damage the red blood cells of those lacking the enzyme. ・Heredity: Passed from parent to child; very rare among Japanese people. ● Main Symptoms: ・Sudden fever, chills, intense fatigue, or dizziness. ・Red or brown urine (hematuria/hemolysis). ・In severe cases, it can be life-threatening.
