真夏のグレイグー

Manatsu Kurashiki is a high school student with top-tier kendo skills but struggles with her studies. Along with her friends Tsumugi Midorikawa, an insect video streamer, and Ayano Yamaji, an occult enthusiast and conspiracy theorist, she is stuck attending a supplementary class on the first day of summer break.

Suddenly, a Self-Defense Force helicopter lands on the school grounds. The soldiers inform the teacher that the town is under lockdown due to a nano machine attack. As the three friends watch from their classroom in shock, their teacher is devoured by a massive swarm of ants. What was supposed to be a boring summer vacation turns into a fight for survival against a terrifying technological threat.
