is the third season of the Magical Girl Lyrical Nanoha series. The Nanoha anime was, in turn, a spin-off of the Triangle Heart series of games and OVAs, specifically Triangle Heart 3: Sweet Songs Forever. This season aired shortly after the promotional event "Lyrical Party III" on April 1, 2007. The series focuses more on team-based battles and bureaucracy rather than individual rivalry and school life, due to the change in character dynamics. The name StrikerS refers to an SS rank given to top mages, much like how A's refers to A rank mages. A special sound stage, under the name of StrikerS Sound stage X was released on October 29, 2008. A manga adaptation, which explored storylines outside of the anime series, ran in Megami Magazine from November 2006 to February 2008. Story Taking place ten years after the events of Magical Girl Lyrical Nanoha A's, Nanoha, Fate and Hayate have joined the Time-Space Administration Bureau and form the Lost Property Riot Force 6. Joining them are four new magical recruits, Subaru Nakajima, Teana Lanster, Erio Mondial and Caro. Together, they face up against the Jail Scaglietti, a dangerous criminal after the Lost Logia. Media Manga A manga adaptation of the anime series was written by Masaki Tsuzuki and illustrated Kōji Hasegawa and was serialized in Megami Magazine between November 2006 and February 2008 issues. The nine chapters were then compiled into two tankōbon volumes by Gakken and published on May 30, 2007 and March 28, 2008, respectively. North American publisher Digital Manga acquired the license for the manga in 2008, but have since cancelled their plans for release and returned the rights to Gakken.
