Grisaia: Phantom Trigger 01 The goal of SORD is to train a new generation of operatives to defend the country against future threats. To that end, the organization has established a series of schools up and down the country. Mihama Academy more-or-less left to rot after its abrupt closure, has been given a new purpose as one such 'specialist training school'. Mihama now entrusts the misfit girls who attend it with guns and live ammunition. Paying their own safety no heed, these students are again and again plunged into dangerous extrajudicial missions - all for the good of the realm. No matter how much life grinds them down, what future awaits these girls, who've themselves chosen the path of the gun? Grisaia: Phantom Trigger 02 A VIP arriving from abroad mysteriously disappears in transit. The SORD team at Mihama Academy is presented with a new mission: finding and recovering him. Whenever they appear to be closing in on this missing "package", though, it somehow slips through their fingers. Accompanying them on their mission are two fellow SORD from the Kyousen Sakuragaoka campus - twin sisters, who both help and hinder the crew. There have also been rumors floating around of a daredevil biker named "Soul Speed", who tears up the streets at night. Before long, the team's thrilling chase descends into a deathmatch, pushing the combatants to their limits and beyond. Rena and Haruto, meanwhile, are taken on a journey deep into the past, to their first-ever encounter. Grisaia: Phantom Trigger 03 While Rena and Maki recover from their injuries, the other SORD members jet off overseas for a school trip. Within moments of their arrival, though, the Mihama gang are pulled into a manhunt for a SORD deserter, assisted by students Sylvia and Velvet of St. Aile's International School. Tohka's the star of the show this time round, but she's wrestling with her own issues - old memories of her parents, and a promise to a friend that she wasn't able to keep... “You're right. There's a reason we need to get back... even if it means crawling home on our hands and knees.” “Let's meet up again someday... if we're still alive.” And introducing Sengoku Ayame - Sengoku Ichiru's brother, and a handler at St. Aile's: “If taking her in alive's too much of a challenge, just get rid of her - I don't give a damn. I simply want to see this mess cleaned up.” What answers will Tohka find? She has the truth in her sights... Grisaia: Phantom Trigger 04 Kumashiro Megumi (Gumi), recently transferred from St. Aile's International School, has been training hard together with Rena and Maki – now fully recovered from their injuries. With the help of her mentor, Tohka, she's shaping up to be a fine sniper. Just as one new student settles in, another has her sights set on joining the girls in Class A, Mihama's elite combat unit. Her name? Sengoku Taiga. Haruto, the team's handler, has one condition for Taiga's transfer: that Chris serves as her supervising officer. The two seem an unlikely pair at first, but after spending some time with little Taiga, Chris soon finds a way to see things from her perspective. It's at that moment that the nation is suddenly rocked by a terror attack on an unprecedented scale. Chris rushes to the scene, aware of what's at stake, but paying no heed to the dangers ahead. Just as she did, once before. "This is even worse than we could've imagined..." The death toll keeps on rising, but SORD are stuck watching helplessly from the sidelines. What destiny awaits Chris, Taiga... and Mihama Academy? "Oh, right... I must have died..." Clutching to memories of her long-dead mother, she too prepares for an eternity of slumber... Grisaia: Phantom Trigger 05 A few weeks have passed since SORD successfully resolved the Kitaoka University terrorist incident - albeit with some sacrifices - when Murasaki's older sister Yuuki returns to Japan and returns to Mihama Academy. Being more sociable and capable than her sister, Yuuki immediately befriends the other students and builds a trusting relationship with them. "There's no reason for me to be at Mihama anymore..." As Murasaki starts questioning her raison d'etre, she reminisces about the time when she first met Haruto. A few years earlier... Lamenting his lack of experience, he had come to her village hidden deep in the mountains in search of new skills. He got to know the Ikoma sisters better and kept up with his training. As he seeks out the village's "secret art", a sudden tragedy befalls them. "I'll never forgive you...!!" "It's okay... Don't worry... I'm not... going anywhere... I'm here with you..." "I'm stumped... It's exactly as she said - and there's no way to cut a phantom..." "Come on. Chin up... Show me your courage..." Their fateful meeting was also the beginning of a tragic story...
