Nisio Isin

Writer · Born November 30, 1980 (45) · Japan

Nisio Isin, stylized NisiOisiN to emphasize the palindrome, is the pen name of a Japanese novelist and manga writer. Born 1981. He attended and left Ritsumeikan University without graduating. In 2002, he debuted with the novel The Beheading Cycle (クビキリサイクル Kubikiri Saikuru), which earned him the 23rd Mephisto Prize at twenty years of age. He currently works with Kodansha on Faust, a literary magazine containing the works of other young authors who similarly take influence from light novels and otaku culture, and Pandora, the Kodansha Box magazine. He was also publishing a twelve volume series over twelve months for the Kodansha Box line; Ryusui Seiryoin was matching this output, and the Kodansha Box website stated that this is the first time in the world two authors have done twelve volume monthly novel series simultaneously from the same publisher. In February, 2008, his novel Death Note Another Note: The Los Angeles BB Murder Cases, which is based on the Death Note manga, was released in English by Viz Media. Del Rey Manga has already released the first and second volume in his Zaregoto series. His Monogatari, Katanagatari and Zaregoto novels have been adapted into anime. The sequel (Nisemonogatari) novel has also been adapted as an anime, as well as most of the "Monogatari Series" to date. Another of his works, Medaka Box, has been adapted into a two-season anime series, along with his light novel Juni Taisen, which has also been adapted into an anime. Source: Wikipedia

Percentiles are each film's standing among all films on Motif; the typical film is the median, so one outlier cannot drag it. Percentiles and reviewer scores count the films IMDb credits them on, for now; the Midcredits score bands, the shape of the crowd and the two cards count their Motif titles, shows included (a show ranked among shows), appearances as themselves left out. A descriptor is the shape of a title's IMDb rating distribution against the catalog; "most divisive" needs a spread wider than half of all titles, and a card names only a principal credit: a craft role, and on a show a crew role or a run of episodes, never a courtesy credit or a one-off guest spot.
