In a quiet mountain village, the girl Watanabe Tomorrow Cuisine (voiced by Hisako Kanemoto) often stands on the top of the mountain, using the mysterious mineral (Gwensi) left by her father as a diode, listening to the wonderful music from outside. On my way to school, Cuisine was attacked by a monster tomorrow. At the critical moment, she was saved by a handsome boy (voiced by Irino Miyu), and pure friendship began to sprout between boys and girls. Tomorrow's cooking tastes the sweetness of friendship, but I don't know that one day I will die quietly. The new male teacher Ryoji Morizaki (voiced by Kazuhiko Inoue) told the children the legend of the country's demise, and tomorrow Cuisine realized that that moment came from another world-Yagutai. Watanabe decided to go to Morisaki tomorrow to learn about the legend of Yachetai, and went to the teacher's house after school. Teacher Morizaki's wife died very early. Her real identity is a soldier belonging to a mysterious organization. Teacher Morizaki told tomorrow's cooking about the underground world. In the evening, Tomorrow Cuisine met Mimi on her way home. Tomorrow Cuisine met a person who looked like an instant when she was chasing Mimi. But they were attacked by a group of masked soldiers. The boy hid in the cave with tomorrow's food, but he was found by the soldiers. The soldier forced Tomorrow Cuisine to open the door of Yagotai with Gwen, and the soldier took off his helmet. It turns out that he is Mr. Morizaki. The boy told Tomorrow Cuisine that he was actually the younger brother of Fast Food-Xin. He only came to the ground to take Gwen away. He pulled Gwen away from tomorrow's cooking neck. Tomorrow Cuisine decided to go deep into Yagutai with Morizaki to find the secret of resurrection. Thus, the two began an adventure.

The two men followed Xie Kuna Weimana for a long time and lived a camping life. At the same time, the elders in the village ordered Xin to drive them away and recapture Gwen, the relic left by her father. Xin cut off her hair and rode off. One rainy night, Mr. Morizaki thought of his wife, whom he didn't see for the last time because of the war. When they fall asleep at night, tomorrow's food will be taken away by outsiders. In the morning, Cathy woke up and found herself in an abandoned castle. She saw a dumb child crying, and the barbarian climbed up and attacked them. At that moment, my mind suddenly appeared and saved them. And the teacher also found a coma tomorrow under the guidance of Mimi. They came to a small village with a broken heart and a little girl. People in the village refused to let them into the village, but because the little girl was the granddaughter of an elder in the village, the elder allowed them to stay in their home for one night in return. The elder explained to them why Yagotai was closed. Tomorrow morning, Cai and Teacher leave by boat, but this time Mimi is no longer willing to go with them. When Xin woke up, she found Mimi dead, and the little girl gave her to aleko. At the same time, the heart saw the group of people who didn't let them into the village during the day yesterday, and they chased after the door of life and death. Knowing that they were going to kill tomorrow's grain, Xin mounted his horse and chased it. If that group of people come up to them and want to kill them, their hearts will come, and they will fight fiercely with them, and they will take the opportunity to escape. Tomorrow they finally arrived at Finiterra, the cliff where the gate of life and death is located. Facing the steep cliff, the teacher climbed down without saying a word, but the steep cliff frightened tomorrow's food, and finally she gave up.

Tomorrow Cai listened to the teacher and returned along the original road. On the way, she had to go by water to avoid the attack of Yi people. And those people left after defeating Xin. On the way back, tomorrow's cooking kept thinking about the past and realized that I came to Yaguotai only because I was too lonely. Night came again, but there was no water where tomorrow's food was, and the Yi people besieged it and wanted to eat it. Just then, the heart suddenly appeared to save her, and it was dawn, and all the Yi people were gone. They looked up and saw Xie Kuna Weimana walking towards the door of life and death. They caught up with them and arrived at Chatter's graveyard with the help of Chatter. The teacher went through a lot of hardships to get there. Gwen suddenly shine at the moment, Xie Kuna mana appeared. The teacher told Xie Kuna Weimana her wish, hoping that his wife Lisa would be resurrected. Xie Kuna Weimana made Lisa's soul appear, but if Lisa wants to be fully resurrected, she must hand over the body that can be put into the soul. At this time, the food of tomorrow suddenly appeared and Lisa's soul entered the food of tomorrow. Tomorrow's food becomes Lisa, and Xie Kunna Wei mana also takes the teacher's eyes as a price. In order to keep tomorrow's food, Xin kept stabbing Gwen with a knife, and finally Gwen was broken, and tomorrow's food changed back.

Xie Ku, Na Wei and mana have left, and tomorrow's food and teachers are on their way home. Tomorrow, the food returned to the ground, but the teacher and Xin decided to stay underground.
