Rebirth

Rebirth (新生, Shinsei) is the first episode of the anime Death Note.

Synopsis
High school student, Light Yagami finds a notebook drop from the sky named the "Death Note". He tests the mysterious powers of the notebook and finds to his astonishment that the book has the power to kill people whose names are written on it. Ryuk, a shinigami, later confronts him at his home, telling him the book belongs to the human owner who found it first and cannot be returned unless the owner dies, completes the notebook or relinquishes ownership. Though initially terrified and distraught by how he killed people, Light decides that he will use the Death Note to kill all the evil people to become the world's new god.
