Lunar Legend Tsukihime - S01

Shiki Toono wakes up in a hospital with the strange ability to see invisible lines-thin threads that compose all matter in Shingetsutan. Severing these lines instantly destroys the object they belong to, and Shiki learns that tracing them leads to the same result. He keeps this eerie power hidden, trying to live an ordinary life as a high school sophomore. But his peace doesn’t last. One day, on his way home, he meets a woman with piercing red eyes. In a sudden, violent episode, he seemingly kills her before blacking out. The next day, demonic hounds attack him, and just as death seems certain, the woman from before appears to save him. She reveals herself as Arcueid Brunestud, a vampire princess. Forced together by fate, Shiki and Arcueid join forces to investigate their shared past and the mysterious murders plaguing the town.
