Death Note
—Episodul 16—

In a plan to remove all suspicions from himself, Light tells L that he thinks he may be Kira subconsciously and asks to be confined. Light’s father believes it is also a good idea to be confined to a cell as well as he cannot risk his emotions getting the better of him. In confinement, Light gives Ryuk the order to have his memory wiped, leaving L confused now that his two suspects both register as sincerely innocent.
