Nisemonogatari

Nisemonogatari is an anime show based on a series of Japanese light novels. The show focuses on the strange life of Koyomi Araragi, who seems to be a normal high school boy. Koyomi is special, however. Some time ago, he was bitten by a vampire and actually became a vampire for a little while. Luckily, he found a man who deals in the supernatural who was able to cure him. Koyomi imagined that he could go back to living a normal life, but this soon proved impossible. After his own supernatural ordeal, Koyomi realized that he could sense other supernatural phenomena. Soon, Koyomi is involved in helping several girls in his high school who are having strange problems.

In Nisemonogatari, Koyomi has had some time to come to grips with the way his life is now. He has become used to helping people who are experiencing strange problems. However, what Koyomi did not expect was that his younger sisters, Karen and Tsukihi, would also become involved in his odd world.

At first, Koyomi does not want his sisters to be involved in solving supernatural cases. In fact, he often argues fiercely with them. However, Karen and Tsukihi soon prove that they have a true talent when it comes to discovering why strange things are happening. In addition, it quickly becomes apparent that, like their older brother, Karen and Tsukihi may have strange backgrounds of their own.

As the series progresses, the two sisters begin to help as many people as they can, solving cases that often seem impossible. The two girls also grow closer to Koyomi. The three siblings form a close bond that allows them to work together efficiently. Each new case is exciting and dangerous in its own way, but by working together, the Araragi siblings can often solve whatever is thrown at them.
