Death Note

When straight-A student Light Yagami picks up a mysterious black notebook dropped by a bored death god, he discovers it can kill anyone whose name he writes while picturing their face. Convinced he can cleanse the world of criminals and rule a purified new order as its god, Light begins a secret killing spree that the public comes to call 'Kira.' But his campaign draws out L, an eccentric, faceless detective every bit his intellectual equal, igniting a razor-sharp cat-and-mouse war of deduction, deception, and nerve. A taut psychological thriller about power, morality, and hubris, this genre-defining manga turns a battle of two brilliant minds into one of the most gripping stories in the medium.
