The property Type Moon teased back in February finally has its own website.
It’s an OVA, and the first disc will be out in the middle of August.
From the cast list, it’s a mashup of Fate/stay night and Melty Blood (and I say that because it’s got characters Tsukihime lacked but Melty Blood did not; it also doesn’t have Avenger, so it’s not drawing from Fate/hollow ataraxia); the character designs look like they drew heavily from those Eri Takenashi (famous for her manga/anime series Kannagi) did for Take-Moon.
A closer look at the staff and cast page says that the source material are the games Tsukihime, Kagetsu Tohya (the sequel to Tsukihime), Fate/stay night, Fate/hollow ataraxia, Melty Blood, and the Take-Moon anthology comics. So Avenger might show up, after all.
The characters all look to be played by the voice actors who’ve portrayed them in the past, so no new surprises there (I only skimmed the list, though).
And now if you don’t know anything about visual novels, anime, or the absolutely bizarre method Japanese game producers use to name their products (there’s no rhyme or reason that I can tell; if it sounds cool and foreign, they’ll use it, whether it makes sense or not), you should be completely confused.
