After transferring to Ishinomori Middle School, Tetsuko "Alice" Arisugawa overhears her classmates discussing a strange rumor. The previous occupant of her seat, a nondescript "Judas," is missing and presumed murdered—poisoned by one of his four wives. Amidst dealing with her mother's undesired meddling in her affairs and warding off her classmates' bullying, the troubled Alice starts to investigate the mystery surrounding Judas' disappearance.

The trail of clues leads her to the house of her next-door neighbor, the quirky and reclusive Hana Arai. After an awkward introduction, Hana agrees to help Alice and formulates a plan that may lead them to the answers they seek. The two girls embark on a journey to uncover what happened to Judas, and perhaps a friendship may start to blossom between the two along the way.

The sequel to Cencoroll.

In the 71st year of the True Era, humans have successfully expanded into space and have started living in independent galactic colonies. The world itself is split between two major nations: the Atlantic Rim United States (ARUS) and the Dorssia Military Pact Federation (Dorssia)—superpowers that wage war against each other on Earth and far into outer space. In this war-torn era, a third faction comprised of Japan and Islands of the Oceanian Republic (JIOR), reside peacefully and prosper economically, maintaining neutrality between themselves and their militant neighbors. Kakumeiki Valvrave commences in an outer space JIOR colony, where 17-year-old Haruto Tokishima's peaceful life is turned upside down as a sudden Dorssian fleet breaches the neutral colony. Their objective is to seize the Valvraves: powerful, but rumored mechanized weapons hidden deep within Haruto's school, Sakimori Academy. In the ensuing chaos, Haruto stumbles upon one of the targeted Valvraves. With his friends' lives in peril, Haruto enters the mecha and seals a contract for its power in exchange for his humanity. With the aid of L-elf—an enigmatic Dorssian agent and gifted strategist—Haruto and the Valvrave initiate a revolution to liberate the world. [Written by MAL Rewrite]
