Melty Blood

A fighting game set after Tsukihime, jointly developed by Watanabe Seisakusho (French Bread) and Type-Moon. It was the first time Tsukihime had voices.
It is the story of a certain vampire and a night of lies, during a summer different than the one in Kagetsu Tohya. The stage progression is in the style of Darius. It seems that a fighting game that advances in such a manner had been something the scenario writer always wanted. Take the upper paths and you'll be treated to a serious story, while the lower paths quickly spiral into absurdity.
The game's subtitle is “Hologram Summer, Night on the Blood Liar.” The original plan was for it to be about an executor who was a sort of rival to Ciel appearing to fight Arcueid, but once production started the sample game ended up being so amazing we felt the need to whip up a worthy story within “Tsukihime Canon” to match.
Of course, with a new heroine, one of the 27 Dead Apostle Ancestors, and even Arima Miyako, it was packed full of fan service, too. So, thank you, Watanabe Seisakusho! The amount of freedom as a fighting game is just great, and the mobility of the characters is off the charts. I hope everybody out there enjoys the pixel-art Tsukihime characters as much as we do!

The title of this work. A series of fighting games based on the visual novel Tsukihime.
The first game, Melty Blood, was the story of the summer one year after Tsukihime. Rumors of vampires once again began to swirl around Misaki, followed soon after by the appearance of the beautiful Sion.
The second game, Re-act, was a bonus chapter with Melty Blood as its base. After the Tatari matter was taken care of, White Len used its power to create a single night of dreams. It was a fighting game with an all-star cast.
This third game, Act-Cadenza, is a further expanded version of Re-act, where nearly everybody that appeared in Tsukihime gets to take on a leading role.
