It's not Tsukihime.

Someone commented: "Tsukihime and Shingetsutan... is about as different as Akiha and Akihabara!" This anime is so much an insult to the original game that I would not have beared to watch it if I wasn't translating it. The story, the characters... were twisted so much that the sparkles of the original work hardly remains. If you had a choice, go buy Tsuki-bako and pretend this anime never happened.
