History
Hundred originated as a Japanese light novel series by writer Jun Misaki and illustrator Nekosuke Ōkuma. SB Creative published the novels through its GA Bunko imprint, beginning on November 15, 2012. The series is set in a future in which humanity is under attack from Savages, mysterious life forms that conventional weapons cannot reliably defeat. The only effective countermeasure is the Hundred, a weapon system able to assume multiple forms. Individuals who can use Hundreds are known as Slayers and are trained for combat and defense. The central protagonist, Hayato Kisaragi, enters the marine academy city ship Little Garden to become a Slayer. His immediate motivation is practical and personal: he hopes to obtain advanced medical care for his younger sister Karen, who suffers from an illness. Hayato's abilities are unusually strong because he is a Variant, a rare survivor of Savage exposure whose compatibility with Hundreds has been greatly enhanced. His arrival at Little Garden leads to a confrontation with Claire Harvey, the academy's highest-ranked Slayer, and to a close relationship with his roommate Emile Crossford. The apparent male roommate is eventually revealed to be Emilia Hermit, a princess whose identity and gender have been concealed. Emilia is also a Variant and possesses the Arms Shroud, an unusually versatile Hundred capable of changing into different weapon forms. The relationship between Hayato and Emilia, together with Hayato's interactions with Claire, Sakura Kirishima, and other female characters, supplies the franchise's romantic and comedic framework. At the same time, the characters' shared history with the Savages connects the academy story to broader questions about biological research, military institutions, and political authority. The novels developed the setting through successive conflicts involving Savage attacks, rival Slayers, royal and governmental interests, and research facilities that experiment with Savage-derived material. Sakura's history introduces a particularly dark strand of the worldbuilding: after becoming ill, she is sold to the Warslran Research Facility, where experimental vaccines derived from Savage fluids are tested on human subjects. The series also introduces Vitaly Tynyanov, a former researcher associated with Warslran who develops Savage-like monsters and uses experimental methods to create or enhance Variant powers. The property expanded beyond prose fiction during its initial run. A manga adaptation drawn by Sasayuki was serialized in Fujimi Shobo's Monthly Dragon Age between the magazine's December 2013 and January 2015 issues. Two collected manga volumes were released on August 8, 2015. The franchise then received a television anime adaptation produced by Production IMS and directed by Tomoki Kobayashi. The anime aired in Japan from April 5 to June 20, 2016, and was licensed for North American release by Funimation. Its music program included multiple opening and ending themes performed by D-Selections and members of the voice cast. The anime production also experienced a cast change involving Charlotte Dimandias. Miyu Matsuki had initially been cast in the role, but Yui Horie replaced her after Matsuki's death in October 2015. The sixteenth light novel volume was published on October 15, 2018, completing the sixteen-volume publication run documented in the reference material. No reliable information in the supplied sources establishes a later continuation, active corporate ownership structure, new screen adaptation, or current official distribution strategy. Accordingly, Hundred is documented as a completed or status-uncertain Japanese media franchise rather than as an active apparel or consumer-goods brand.
