Fragments// Akitoya// Project Sekai AU

[Project Sekai AU] The peaceful routine of the Kamiyama High School students abruptly takes a tragic turn as an unexpected phenomenon strikes their city. "Fragments", a mysterious occurrence, descend upon the city, causing widespread panic and changing the lives of its citizens.

With the situation intensifying, the group of Kamiyama High School students strive to uncover the cause behind the incident while also searching for the missing Miku. Among them, Rui Kamishiro discovers compelling leads, connecting the phenomenon to a foreign realm all the students have visited in different variations.

Unsettling events persist both in the real world and "Sekais", creating a sense of hopelessness among the students as they struggle to forge their path forward and reach an agreement on how to proceed.

(Primarily focuses on Kamiyama High School students, as well as some students from Miyamasuzaka.)
