Document 3: Sky High (2003 film): Sky High (スカイハイ , also known as "Skyhigh") is a supernatural action film from director Ryuhei Kitamura. It is based on the manga of the same title by Tsutomu Takahashi and serves as a prequel to a Japanese television drama of the same name, and starring the same actress, Yumiko Shaku. Although the film is a prequel to the series, the film was made while the series was still in production, sometime between the first and second seasons. The film had a clear effect on the direction of the second season, as evidenced in the look and style of Mina/Izuko's second season costuming—more similar to the darker, edgier look she sports in the film, as opposed to the softer, colourful, kimono-like outfit of the first season. The film reveals how the somewhat meek Mina became the heroic Izuko, as seen in the series (and the film’s action climax).
Document 4: List of Hatoful Boyfriend characters: This is a list of characters from the visual novel, web series, and webcomic "Hatoful Boyfriend", and its sequel, "" by PigeoNation Inc. The games take place in the year 2188, and the story follows the main protagonist, a girl who is the only human student at St. PigeoNation's Institute, a high school for gifted birds. There are eight love interests in the first game who along with the protagonist make up the main cast of the series: Ryouta Kawara, the protagonist's kindhearted childhood friend; Sakuya Le Bel Shirogane, a haughty exchange student and nobleman from France; Yuuya Sakazaki, a flirtatious but shifty upperclassman; Nageki Fujishiro, a quiet and mysterious freshman; San Oko, an athletic, pudding-obsessed jock; Anghel Higure, the school eccentric; Kazuaki Nanaki, the school's helpful but narcoleptic math professor; and Shuu Iwamine, the creepy, suspicious school doctor. The dating simulation portion of "Hatoful Boyfriend" focuses on the protagonist's interactions with each of the love interests and the relationships that result, while the darker "Bad Boys Love" route of the game instead follows Ryouta, attempting to figure out the identity of the protagonist's killer after she is murdered. "Holiday Star" takes place in an alternate timeline in which the events of "Bad Boys Love" do not occur, and removes the otome game aspects of the first game in favor of a more linear storyline split into four chapters—the first two chapters are largely comedic, while the latter two chapters take place on the oneiric Holiday Star.
