For the protagonist, enrolling in a specialized academy for those like him is his only escape.

Senren Banka — deep in the mountains lies Hori, a small village so distant from everyone that trains do not stop there. Thanks to her isolation from the world, she was able to withstand the spread of universal urbanization. Its attractions and a hot spring have made this place a famous tourist destination. One of the most visited places here is the magic sword of Murasamemar, whose sheath became a huge boulder, from which no one was able to pull it out. Our main character, Arici Masaomi, trying to pull him out, accidentally broke a legendary sword.

From this moment, the repetition of events from that day begins, which resemble a space-time trap. The protagonist is forced to look for a way to break the chain of repetitions in order to finally save his life. Along the way, players will talk to pretty girls and engage in a variety of interactions with them in the form of a visual novel.
