Type-MOON is a former doujin circle (now a corporation), most well known for the creation of the Tsukihime and Fate/Stay Night Visual Novels. Both VNs are highly regarded works that have generated numerous spin off titles, most often in the fighting genre. Both games (as well as the Kara no Kyoukai novel) have also had anime adaptations.
Kinoko Nasu (hereafter referred to as "Nasu") is the author of Type-MOON's works, while Takeuchi is the illustrator. Type-MOON was founded in 2000 by Nasu and Takeuchi, after collaborating together on the novel Kara no Kyoukai (which was completed in 1999). Type-MOON's first official release was the Visual Novel Tsukihime, released in December of 2000. Tsukihime saw great commercial success and is largely responsible for the currently massive worldwide fanbase for Type-MOON's works. The following month, Type-MOON released Tsukihime Plus+Disc, which featured side stories and various Tsukihime related images. In August of 2001, Kagetsu Tohya was released; a fan-disc with a new story taking after the events of Tsukihime, as well as offering some more side stories and related media that provide further background to the Tsukihime universe. In 2003, Type-MOON released Tsukibako, a special package containing Tsukihime, Plus+Disc, Kagetsu Tohya, modified audio tracks for the games, and more.
In 2004, Type-MOON officially transitioned from a doujin soft developer to a corporation. Shortly thereafter they released another VN, Fate/Stay Night. Fate/Stay Night saw immediate commercial success, prompting an anime adaptation in 2006. In 2005, Fate/Hollow Ataraxia was released, a Fate/Stay Night fan disc revolving around the events "after" the 5th Holy Grail War (the nature of the story makes it difficult to truly say "after" the war).
Type-MOON has collaborated with other doujin soft developers, most notably the developer French-Bread in creating the Melty Blood series. Melty Blood, released in 2002, revolves around the Tsukihime universe. The original Melty Blood has seen many expansions and changes, and since its release there have been two follow up titles in the series: Act Cadenza and Actress Again.
- Mahou Tsukai no Yoru - Witch on the Holy Night: The original story, it details the lives of Aoko Aozaki, Alice Kounji, and Shizuka Sojuro. Originally an unreleased novel with extremely limited copies, it has been adapted into a Visual Novel for an April 12, 2012 release. It is Type-Moon's first All-Ages visual novel.
- Angel Notes (Notes): A short story about an apocalyptic future. After the death of Gaia, the 'Ultimate Ones' invade the planet and destroy the rest of humanity. The work provided a lot of the concepts that later became bases for the Nasuverse.
- Kara No Kyoukai - The Garden of Sinners: The first collaborative project between Nasu and Takeuchi, Kara no Kyoukai is a novel focusing on the events occurring in the life of Ryougi Shiki. Being one of Nasu's earliest works, Ryougi is a sort of basis for other characters created by Nasu later on. For example, her Mystic Eyes of Death Perception are shared by Tohno Shiki of Tsukihime, but his eyes have been "weakened" by Nasu in that they cause great stress on his mind.
- Tsukihime: The first visual novel officially released by Type-MOON, it is the story largely responsible for creating the massive Type-MOON worldwide fanbase. The story follows the life of Tohno Shiki after moving from his relatives' home to his old home, the Tohno Mansion.
- Tsukihime PLUS+DISC: A Fan Disc with a new short story, and various other little stories expanding the world.
- Kagetsu Tohya: A Fan Disc that is an indirect sequel to Tsukihime.
- Melty Blood: A story-heavy fighting game that is a sequel to Tsukihime, following an unreleased route.
- Tsukihime 2/the dark six: An as-of-yet unreleased sequel to Tsukihime. It was revealed in Kagetsu Tohya.
- Tsukihime Remake: A newly updated version of the original game, including the route that leads into Melty Blood. Unreleased.
- Fate/Stay Night: Fate/Stay Night was actually released after Type-MOON officially became a corporation. The game follows the life of Emiya Shirou after he is thrown into the 5th Holy Grail war, a battle pitting magi and their servants against each other in a quest to find the "Holy Grail".
- Fate/Zero: A four-part light novel series detailing the 4th Holy Grail War, and the events leading up to Fate/stay night.
- Fate/hollow ataraxia: A Fan Disc sequel on the line of an unreleased route, this follows the story of a character supposed to be dead in Fate/stay night, and the mysterious Avenger class Servant.
- Fate/unlimited codes: A fighting game that follows the events of Fate/stay night, but with the basis of asking "What if this character was the protagonist?". Also features characters from hollow ataraxia and Zero, along with original characters.
- Fate/tiger colosseum: A fighting game for Playstation Portable, which is mainly a parody of the original game. Taiga Fujimura begins the fight for the 'Tiger Grail', and Masters and Servants compete to claim it.
- Fate/tiger colosseum UPPER: An expanded rerelease of tiger collosseum, which adds characters from hollow ataraxia, Zero, and Tsukihime.
- Fate/EXTRA: An RPG for Playstation Portable, the player gets to choose the Master's gender, and pick between Saber, Archer or Caster as his or her Servant for the game. It follows a new style Holy Grail War run by the Serial Phantasm (SE.RA.PH) between 128 Masters over the course of eight weeks.
- Fate/EXTRA CCC: A sequel-of-sorts to Fate/EXTRA, it follows the same concepts and gameplay as the original with a brand new story and characters. You can still pick your Master and Servant in this game.
- Fate/Apocrypha: Originally set to be a MMO, and now a light novel series. It's a Holy Grail War that plays differently to the standard fare.

Every 10 years, the 'Carnival Phantasm' begins and worlds merge in order to become a huge force, beginning "The Carnival". The series follows one of these Carnivals.
- Decoration Disorder Disconnection (DDD): A series of unconnected novels centered around literal demons throughout the Nasuverse.
