In a bid to profile Light's behavior, L challenges him to a game of tennis. L asks him some questions regarding the Kira case and invites him to help in the investigation. The two then receive news that Soichiro Yagami has had a heart attack and is in the hospital. Light promises to his father that he will make sure Kira is caught and executed for making him suffer. On the way out, L confronts and scrutinizes Light, still uncertain whether or not he is Kira. Light attempts a bluff and demands to be placed in a prison cell without television for one month to prove his innocence. L is satisfied but curious that Light should offer this proposition. Meanwhile, television station Sakura TV receives audio tapes from an anonymous person claiming to be Kira.
