Century Soup is a rare and high-class soup, considered one of the greatest soups in the world.
A soup cooked with hundreds or even thousands of ingredients. The taste of the soup can also be reproduced with different ingredients boiled down so that the harsh taste is removed and only an extremely transparent liquid remains. The soup is so transparent that many have difficulty even seeing it. Even so, a “true” Century Soup produces a characteristic aurora.
Century Soup is extremely delicious and deeply flavorful, despite its insubstantial appearance. It is described as being an ancient flavor filled with innumerable savory tastes that gradually unravel on the tongue and awakening primitive taste senses that have been sleeping until now.
Virtually anyone who eats it displays a characteristic dopey grin of extreme happiness. The happiness it induces even affect animals.
