Watari

Watari (ワタリ) is L's assistant, providing logistics to the investigation team. Before the team is formed, he is the only person who has seen L, and the only one capable of contacting L directly. Like L, he represents himself with an Old English "W" on computer screens. On the surface he is Quillsh Wammy (キルシュ・ワイミー, Kirushu Waimī), a famous inventor and founder of Wammy's House, an orphanage for gifted children in Winchester. Watari is well trained in espionage and marksmanship. He is voiced by Kiyoshi Kobayashi in the Japanese anime and French Tickner in the English dub. In the film, he is played by Shunji Fujimura.

According to Death Note: How to Read 13, Watari was originally designed to be man with only a single strip of hair. Illustrator Takeshi Obata redesigned him as an old man.
