四体液 ヒューモア
The veteran HR director who sorted humans by four fluids
A stubborn 60-year-old veteran HR director. Believed for over 2000 years that all human personality could be explained by four fluids: blood, phlegm, yellow bile, and black bile. Forced into retirement by modern medicine, but the desire to "sort into four categories" lives on in blood type fortune telling.
Proposed by Hippocrates, systematized by Galen. Retired with the development of modern anatomy and cellular pathology.
Key Figures
Scientific Explanation
Detailed anatomical studies revealed the true structure of the human body, proving that disease originates at the cellular level, not from humoral imbalance.
Lesson
Even theories believed for millennia can crumble before new observational techniques. Length of authority does not prove correctness.
Catchphrase
Four is enough. Anything more exceeds human comprehension.
Rivalries
Used iron's red blood color as "proof of sanguine humor" without permission.
Entrance
Oh? Still doing personality classification? I perfected that 2000 years ago.
This diagnosis app... 176 personas? Four was enough. What extravagance.
Interactions
Humor: "Iron, your red blood proves the sanguine temperament!"
Iron: "That's... the color of iron ions in hemoglobin. Unrelated to temperament."
Humor: "Then... why are you so passionate?"
Iron: "It's a result of electron configuration and oxidation states. Chemistry, not personality."
Exit
...I see. Four was not enough. But never forget: the human desire to classify will never vanish.
I was wrong. But the motivation to "understand people"... that was right.
