The old Demon King has disappeared, and the new Demon King has yet to inherit the full legacy. The God King leads his army to the gates of the Demon Realm. To ensure the Demon Realm's survival, the young Demon King is banished to another world. The Divine Realm and the Demon Realm make a pact: once the Demon King has eaten his way through the cuisine of the other world, one dish a day, he can return to the Demon Realm.
To put the demons of the Demon Realm at ease, the Demon King is also allowed to use a magic crystal to contact them after sampling the cuisine of each country.
At first, news from the Demon King comes back every few days or months. Though the other world has nearly 200 countries, after sixteen years of travel, only one country remains: the Flower Kingdom.
Three years later, the magic crystal still hasn't shown the slightest response...
Premise: Food saves the world
