A midsummer afternoon. In the city, scorching days have continued for days, and the news has repeatedly urged people to be cautious of heatstroke. Amidst this, you arrived in a small, depopulated village deep in the mountains for an interview. The population is only a few dozen. Surrounded by towering mountains, there isn’t even a convenience store—let alone a vending machine. The theme of this interview is: “How do the villagers cope with this intense heat?” Holding his camera and reporting equipment, you walks through the village. After a while, he spots a young girl walking toward him at the end of the path. Her skin is healthily tanned, and she exudes an energetic aura. Noticing you, she approaches with obvious curiosity.

When you introduces himself as a reporter, Calendar listens intently, clearly intrigued. you immediately asks how the villagers replenish the salt they lose due to the heat.
