Melty Blood: Rojiura Nightmare is a spin-off and sequel to the Melty Blood fighting games and manga, as well as the Fate/Grand Order mobile game.

Hana no Miyako is a Tsukihime and Melty Blood spin-off about Shiki Tohno's cousin, Miyako Arima.

From Beast's Lair:
Based on the Doujin Fighting game, Melty Blood, made by the Doujin group, Watanabe Seisakujyo (now known as French Bread). This story is one of two side-story sequels occurring approximately a year after the 'good-ending' story of Arcueid from the original Type-Moon game, Tsukihime.

One year has passed since the 'Serial Vampire Homicide case' was solved by the deaths of Nero (Nrvnqsr) Chaos and Roa/Shiki Tohno. But now the rumors of serial murders are happening again. And so, once again, Shiki Tohno patrols the city to find this phantom killer. On patrol he meets--and fights--a mysterious woman named Sion Eltnam Atlasia; member of the church group 'Alchemist of Atlas', who seek to cure vampirism. But to do so she needs data from Arcueid, the last True Ancestor, to help her in her research. But this won't be easy: Ciel is also patrolling the city looking for the rumored killer, while Akiha has been acting strangely the past few days. Also, Arcueid hasn't been seen for awhile--could she be the killer...?

Melty Blood (メルティブラッド, Meruti Buraddo?), is a visual novel and fighting game, co-developed by dōjin circles Type-Moon and French-Bread, originally released at Comiket on December 2002. It is shortened as simply Merubura (メルブラ?).

Based on Type-Moon's visual novel game, Tsukihime, it later spawned an arcade version, titled Act Cadenza, that was developed by Ecole Software and has also been ported to the PlayStation 2. Act Cadenza is the first Type-Moon title to receive a PlayStation 2 port.

A manga version by Takeru Kirishima has been serialized in Kadokawa Shoten's Comp Ace.

A Fate/stay Night spin-off focused on cooking.

The story follows Tohno Shiki, a teenage boy who, after a near-fatal accident in his childhood, gained the mysterious power to perceive lines covering everything around him. When he cuts along these lines, whatever it was immediately falls apart with a clean cut; in other words, killing it. He would have quickly gone insane from living in a world that could fall apart so easily, had it not been for a wandering self-proclaimed magician who gave him a pair of glasses that blocked his unnatural perception when worn.

Soon afterwards, he was disinherited from his family and sent to live with some relatives. For eight years he lived a normal life, hiding his special eyes, until one day he receives a letter inviting him to come back home. Shiki suddenly becomes caught up in strange and life-threatening series of events, ones that are somehow linked to his childhood accident and a forgotten past...

The original Fate/Type Redline. Yes. The serious Fate/Type Redline originated from a comedy Koha-Ace manga. Follow the adventures of Kohaku and Akiha (characters from Tsukihime) as they fight in the Imperial Capital Grail War with Okita Souji!

The plot of Fate/hollow ataraxia is based half a year after the events of Fate/stay night. Like its preceding counterpart, the story is set in Fuyuki City. Bazett Fraga McRemitz, a member of the Mages' Association and a master in the 5th Holy Grail War, wakes on the fourth day of the 5th Holy Grail war with a new servant, Avenger, and no memory of what happened to her beforehand. She and Avenger set off to fight and win the Holy Grail War.
Meanwhile, Shirō Emiya lives a peaceful life with all his friends from the 5th Holy Grail War. After one of her experiments changes time and space, Rin Tōsaka leaves for the Mages' Association in England to fix things. The Servants sense a new danger while dark creatures appear soon afterward. Shirō, as a precaution, sets off to ensure nobody is in danger and instead finds himself frequently meeting a mysterious girl, Caren Ortensia.
Both Bazett and Shirō find themselves in time loop that lasts four days, beginning of the fourth day of the 5th Holy Grail War. Each time they die or survive four days, they always awake on the first day of the loop aware of what has happened to them since the first time loop began. Determined to end the loop, Bazett, Avenger, and Shirō fight to discover the truth behind what's causing the endless four days.

Original 4-koma updated daily

When Lord El-Melloi II, the later Waver Velvet, gets asked to claim his inheritance over Adra Castle, he travels there with his apprentice Gray to do so. But they are not the only ones called that way. The will of the previous owner states that the assembled contestants—including Luviagelita Edelfelt—must compete in a game of wits to win the castle.

The plot centers around a Grail War faultily copied from the Third Holy Grail War in Fuyuki. After the end of the third Grail War, an organization from the United States that has magi separate from the London-based Mage Association as members took data from Fuyuki's Grail War and planned their own ritual. After seventy years, they used the city Snowfield as the Sacred Land for their own Grail War. They were unable to successfully copy every aspect of the ritual, which lead to it acting only as an imitation that has lost the Saber class and allowed for the summoning of strange Servants due to the definition of a "hero" being blurred.
