A Little Princess is a children's novel by Frances Hodgson Burnett, first published as a book in 1905.
 It is an expanded version of the short story "Sara Crewe: or, What Happened at Miss Minchin's", which was serialized in "St. Nicholas Magazine" from December 1887.
 According to Burnett, after she composed the 1902 play "A Little Un-fairy Princess" based on that story, her publisher asked that she expand the story as a novel with "the things and people that had been left out before".
 The novel was published by Charles Scribner's Sons (also publisher of "St. Nicholas") with illustrations by Ethel Franklin Betts and the full title "A Little Princess: Being the Whole Story of Sara Crewe Now Being Told for the First Time".
Galactic Gale Baxingar (銀河烈風バクシンガー , Ginga Reppū Bakushingā ) is a mecha anime series that aired from 1982 to 1983 in Japan.
 There were 39 episodes released.
 Other loosely translated names include "Baxinger", "Galactic Stormwind Baxinga" and "Cosmo Rangers".
 It is the second of the J9 Series, serving as a sequel to "Braiger" and is followed by "Sasuraiger".
 Its plot was based on the Japanese late Tokugawa period and the story of the Shinsengumi samurai.
Najica Blitz Tactics (Japanese: ナジカ電撃作戦 , Hepburn: Najika Dengeki Sakusen ) is an anime television series by Studio Fantasia.
 It premiered across Japan between October 5, 2001 and December 27, 2001.
 The show is similar to that of "Agent Aika"—both being directed by Katsuhiko Nishijima and animated by Studio Fantasia—with much of the same content.
Strain: Strategic Armored Infantry (奏光のストレイン , Sōkō no Sutorein ) (stylized as Str.A.In.: Strategic Armored Infantry) is a mecha anime series by Studio Fantasia.
 It premiered across Japan on WOWOW from November 1, 2006.
 A manga adaptation is being serialized in the "Dragon Age" magazine.
 The concept of the series is loosely based upon Frances Hodgson Burnett's novels, most notably "A Little Princess", but also "Little Lord Fauntleroy" and "The Secret Garden".
 The series also draws some elements from the Gundam franchise.
 On May 15, 2008, Texas-based licensor FUNimation Entertainment announced its licensing of "Strain: Strategic Armored Infantry".
 The anime was available in a complete DVD release on January 27, 2009 across North America.
Metal Armor Dragonar (機甲戦記ドラグナー , Kikō Senki Doragunā ) is a 48-episode mecha anime series, created by Sunrise and aired from 1987 to 1988.
 Devised shortly after the release of "Mobile Suit Gundam ZZ", Dragonar was intended to be both a "starter" series to get new fans into mecha anime, and a potential successor to the Gundam franchise.
 In fact, its concept is to be the renewal of the first Gundam.
 Though the series enjoyed good ratings and earned a loyal fan following, it failed to surpass Gundam and ended up as a single series, probably due to its light, ZZ Gundam-like take on the real robot mecha genre.
 Game developer Banpresto had Dragonar appear in two of its popular franchises, "Super Robot Wars" and "Another Century's Episode"; fans responded positively, and Sunrise acknowledged them in 2005 by releasing a memorial DVD collection of the series, a remastered version of the previous two-part LD boxset releases years before.
Valvrave the Liberator (革命機ヴァルヴレイヴ , Kakumeiki Varuvureivu , lit.
 "Revolution Machine Valvrave") is a Japanese mecha anime series, produced by Sunrise.
 It is directed by Kō Matsuo and written by Ichirō Ōkouchi.
 The series is set in a futuristic date in which three factions divided from 70% of mankind are in war.
 It focuses on Haruto Tokishima, a high school student from the faction of JIOR who pilots one of the highly advanced weaponized mecha technology called the Valvrave to stop the Dorssian forces.
"Buddy Complex" is a 2014 Japanese mecha anime series produced by Sunrise in collaboration with Bandai Visual, Bandai Channel, Lantis, Banpresto, and Bandai Namco Games under Bandai Namco Holdings.
 The anime series is original creation of Hajime Yatate and is directed by Yasuhiro Tanabe with series composition by BC project, original character designs and animation direction by Asako Inayoshi and Tomoshige Inayoshi, soundtrack music by Tatsuya Kato and 3D CG by Orange.
 The series follows Aoba Watase, an ordinary high school boy who lived an average, everyday life commuting to high school in the city.
 On the first day back after summer break, Aoba is attacked by a giant robot that appears out of the sky.
 As he's pursued through the city, his classmate Hina Yumihara appears in a giant robot of her own.
 She rescues him, and tells him cryptically that "Dio is waiting," before she sends Aoba into the future and then disappears.
 When Aoba wakes up, he finds himself over seventy years into the future, where the Free Pact Alliance and the Zogilia Republic are at war with each other and there he meets young pilot named Dio Jyunyou Weinberg.
 This begins Aoba's new life as the pilot of the Free Pact Alliance and together with Dio, they would change the fate of the world.
Armored Trooper VOTOMS (装甲騎兵ボトムズ , Sōkō Kihei Botomuzu ) is a military science fiction mecha anime series, having undergone several incarnations.
 The original 1983 television series was created by Ryosuke Takahashi and Sunrise, featuring mechanical designs by Kunio Okawara.
 Following directly in the footsteps of Takahashi's previous series, "Fang of the Sun Dougram", "VOTOMS" continued the trend towards hard science in the mecha anime subgenre.
 The series was supplemented by numerous original video animation releases, and also inspired a number of spin-off works whose media ranges from serialized light novels to video games.
