You're coming in expecting a harem wrap-up and instead get five different love stories that actually matter, each one built on damage that doesn't disappear when the credits roll. The prologue shows you who these girls were before Yuuji, which means watching them choose him hits different. Romance here isn't window dressing for action beats, it's the reason the whole thing exists, and the show trusts that enough to let a story about broken people learning to stay broken together carry the weight of a trilogy conclusion.
Picking up right where the previous installment ended, Yuuji Kazami is arrested on suspicion of terrorism after a video appears to prove his guilt. He is held by Ichigaya, who knows he is innocent of those crimes but also knows he failed to assassinate Heath Oslo, leader of a terrorist group holding a devastating weapon, and has plans of its own for him. Meanwhile Mihama Academy is set to close within the month for financial reasons. Amane, Makina, Sachi, Yumiko and Michiru, who have grown with Yuuji's help over the past year, refuse to let him be used for political gain and take on countries and organizations far larger than themselves. A mysterious new figure also appears. The 10-episode TV series mixes action, drama, romance and ecchi.
