Mihama Academy - on the surface, a closed learning environment established to nurture students who find themselves at odds with the world around them; in actuality, a prison built to preserve fruit that has fallen too far from its tree. Whatever the circumstances behind its establishment, Mihama Academy is at present home to five female students, all with their own reasons for "enrollment". For better or worse, each girl has established a routine obliging of her current situation; life moves at an idle, yet accommodating pace within the walls of Mihama.Yet with the arrival of the institute's first male student, the nearly preposterously opaque Kazami Yuuji, the students at Mihama begin to fall out of step with their predetermined rhythms. Will Yuuji prove to be the element the girls around him needed to take hold of their lives once more, or will the weight of their pasts prove too steep a wall to overcome?And in the first place, just who is he? While the true nature of the "job" he is wont to alight to at the most haphazard of moments remains shrouded in secrecy, one thing is for certain: his encroachment upon the quiet orchard known as Mihama Academy will prove itself momentous in one way or another. And of course, one cannot discount the possibility that perhaps Yuuji himself carries the weightiest past of any of the students...

Specials episode of Grisaia no Kajitsu

Roughly a year after his arrival at Mihama, Yuuji makes the unexpected decision to pursue promotion within CIRS. The action resumes with Yuuji in a meeting with JB at "corporate HQ," discussing the documents he submitted for review as a part of the promotion process—said documents pertaining to none other than Yuuji's own past. Meanwhile, back at the dorm, the girls find themselves unwittingly following along after Sachi and Makina restore the shredded rough draft of said documents. The irony, of course, being that prominent figures in Yuuji's past may just be continuing to exert their influence upon the present...

Special bundled with the Blu-ray/DVD volume of Grisaia no Meikyuu.

The story picks up immediately after the events of Grisaia no Meikyuu, with Kazami Yuuji having been detained for suspected involvement with an international terrorist organization, lead by Heath Oslo, that has managed to enter Japan's borders with a devastating new weapon of mass destruction in hand. Meanwhile, at Mihama Academy, the remaining students find themselves with time running out - due to financial issues, the school is set to close within the month. Over the past year, though, the girls of Mihama have finally begun to find their own legs, thanks to Yuuji's involvement - are they really just going to bury their heads in the sand and let the world change around them? And are they really willing to let the man who changed their lives slip away without so much as trying to win him back? As the end of their time at Mihama Academy approaches, Amane, Makina, Sachi, Yumiko, and Michiru find themselves arriving at a single conclusion. How much a group of students can do in the face of countries and organizations far bigger than any individual could hope to be remains to be seen. In the first place, Yuuji's position is far more complicated than any of them could have imagined, as he finds himself embroiled in an elaborate game of super-political chess revolving around both himself and an inconceivable new system slumbering in the depths of CIRS - a system that Yuuji may have more of a connection to than he thinks. One thing is for certain, though - the girls of Mihama are no longer willing to let the world steal things away from them without at least a bit of resistance first. And with help from a mysterious individual known only as Thanatos, they may just achieve their goal...

Short specials included in the Blu-ray and DVD releases.

Following the Heath Oslo incident, the existence of the US-Japanese anti-terror organization CIRS has become a matter of public knowledge. CIRS has been rebuilt from the ground up, and its most covert functions spun off to a new agency: SORD (Social Ops, Research & Development). 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 new purpose as one such 'specialist training school'. This new incarnation of Mihama Academy is home to a diverse group of students, who every day work to polish their unusual skills – sometimes on the job. 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. "We've been provided with a place in the world. That alone isn't enough - there wouldn't be any meaning in living, if that was all we had... It's not enough just to be made use of by others. I live by my own strength, and I fight to survive. That's the only way those of us who actually make it through can find forgiveness..." No matter how much life grinds them down, what future awaits these girls, who've themselves chosen the path of the gun?

Long ago, a war was waged between the forces of darkness and light as Dark Brings—stones containing dark power beyond human ability—put the world at risk with their destructive force. In order to stem the tide of darkness, a lone swordsman used holy power known as the Rave to destroy the source of every Dark Brings. The resulting explosion, which came to be known as the Overdrive, destroyed a tenth of the world; fragments of the Rave were scattered throughout. Groove Adventure Rave takes place fifty years after the Overdrive. A group known as Demon Card has collected the remaining Dark Brings, using them to lay siege to a number of towns. Meanwhile, a young swordsman by the name of Haru Glory has inherited both the Rave and its guardian, Plue, making him the next Rave Master. With the aid of an amnesiac drifter by the name of Elie and a silver-manipulating blacksmith by the name of Musica, Haru must scour the world in search of the scattered Rave Stones and put an end to the Dark Brings and Demon Card for once and for all.
