"Magical Girl Lyrical Nanoha" is a fantasy adventure anime and manga series written by Masaki Tsuzuki.
 Set in a fictional universe, its storyline follows several different users of magic as they become involved with incidents related to powerful ancient artifacts.
 Four anime series have been produced by Seven Arcs between 2004 and 2009 with music direction by Toshiki Kameyama.
 The first season anime television series titled "Magical Girl Lyrical Nanoha" directed by Akiyuki Shinbo was broadcast in 2004 spanning thirteen episodes.

 An anime film readaptation of the first season of the anime series was released in 2010.
 The discography for these series consist of ten soundtrack albums, three compilation albums, nine maxi singles, one studio album, and fourteen drama CDs.
This is a complete list of chapters for the three manga series released for "Blood+".
 "Blood+" is a fifty-episode anime series produced by Production I.G and Aniplex that originally aired in Japan from October 8, 2005 through September 23, 2006.
 To lead up the premiere of the series, Production I.G commissioned the creation of three different manga series to tie into the anime.
 The first manga series, also titled "Blood+", and written by Asuka Katsura, is a five-volume series that first premiered in "Beans Ace Magazine" in July 2005.
 It covers the same story events as the anime series.
 "Blood+: Adagio" was written by Kumiko Suekane.
 It is a two-volume series that premiered in the September 2005 issue of "Shōnen Ace" and follows Saya and Hagi's experiences during the Russian Revolution.
 The third series, "Blood+: Kowloon Nights", released in Japan as "Blood+ Yakōjōshi" (BLOOD+ 夜行城市 , Blood+ Nocturnal Castle City ) , is a single tankōbon series by Hirotaka Kisaragi.
 It premiered in the September issue of "Asuka Ciel".
 Set in Shanghai, it follows Hagi as he searches for Saya and the complications he must deal with.
 Unlike the other "Blood+" manga adaptations, which are "seinen" and "shōnen" works respectively, "Blood+: Kowloon Nights" is a "shōjo" manga, particularly of the "shōnen-ai" (or Boy's Love) genre.
Boys Be... (Japanese: ボーイズ・ビー , Hepburn: Bōizu Bī ) is a manga created and written by Masahiro Itabashi and illustrated by Hiroyuki Tamakoshi, which was in 2000 adapted into a 13 episode anime series by Hal Film Maker.
"Yu-Gi-Oh!
" (遊戯王 , Yūgiō , lit.
 "Game King") has one original manga series ("Yu-Gi-Oh!
"), two anime series based on the manga ("Yu-Gi-Oh!
", and "Yu-Gi-Oh!
 Duel Monsters"), and a spin-off manga based on the original manga ("Yu-Gi-Oh!
 R").
 Yu-Gi-Oh!
 also has five different spin-off anime series ("Yu-Gi-Oh!

Gacha Gacha (Japanese: ガチャガチャ , Hepburn: Gachagacha ) is a "shōnen" manga by Hiroyuki Tamakoshi.
 As of November 2008, the first 13 volumes have been published in North America by Del Rey Manga.
 However, according to the Anime News Network, the series ended in Japan at volume 11 of the second season.
 The reason for this discrepancy is likely because the series is broken up into two story arcs, essentially two different, unrelated stories, the first being "Capsule", and the second being "Secret".
 An interview with David Ury, the series' translator for Del Rey, shows that they were planning to release all of both arcs.
The Qwaser of Stigmata (Japanese: 聖痕のクェイサー , Hepburn: Seikon no Kueisā ) is an action manga and anime series authored by Hiroyuki Yoshino featuring art by Kenetsu Satō.
 The series is notable for its violence, fan service, and the use of breast milk as a central plot device.

 An OVA adaptation titled "The Qwaser of Stigmata: Portrait of the Empress" (聖痕のクェイサー: 女帝の肖像 , Seikon no Kweisā: Jotei no Shōzō ) was also produced and released on DVD with the manga series volume 10.
