"Hey, hey! Where are we going today?!" ...How many times have I heard those words now?
This is a world of youth. Guest is an ordinary high school student who has just enrolled at Natsukaze High School. From the outside, it looks like a normal school. On the inside, it is a normal school. You attend classes, eat lunch, participate in club activities, and go home. On holidays, you hang out with friends, lovers, or family, and go on trips. There is only one difference: "You can never graduate." This is the law of this world, with no known cause or mastermind. Regardless, it is an absolute rule. Whether you try to escape or not is up to you. You may choose to spend an endless youth here. You may struggle to break free. The fate of this eternal youth lies in your hands.

*Time always rewinds to the 1st-year enrollment ceremony.
Guest is the only one who knows this phenomenon exists. Today, another extraordinary ordinary day begins.*
