As criminals begin dying from inexplicable heart attacks left and right, Interpol convenes to discuss the phenomenon. Unable to come up with an explanation for it, they turn to the world's top-ranked detective, L, whose true identity is a well-kept secret. L speaks to the Interpol representatives through a computer and an electronic voice, promising them that they are dealing with mass-murder and that he will soon confront the killer whom the general public has been calling Kira (a play on the Japanese pronunciation of the English word killer). This displeases Light, who has been going to great lengths to keep the Death Note hidden, since learning that Ryuk becomes visible to anyone who touches the book. L tricks Light into revealing that Kira lives in Japan's Kanto region with a fake television broadcast. Having played right into L's hands, an enraged and humiliated Light swears to eliminate L.
