Years after The Fruit of Grisaia...
The place once known as 'Mihama Academy,' a haven for young women, has now become a SORD (Special Organization for Research & Development) academy devoted to cultivating talent for national security. Rena and Maki focus on firearms, Tohka and Gumi are experts in sniping, Chris manages explosives and data analysis, while Murasaki serves as a covert ninja for intelligence missions. Together they tackle cases beyond the reach of police or Self-Defense Forces, repeatedly confronting perilous assignments. This is the tale of these young women, once rendered in blood and gunpowder.
