First Impressions (Edited)

Young Ori Nanase is your average high school student: smart, pretty, fun, but things get weird when her best friend, Light Yagami, starts acting weird, then, L, her favorite detective, tells Ori that Light is the prime in the Kira-Case. Kira is a killer with no real name or face. They kill criminals and need the names and faces of others to do so. When L tells Ori his suspicions, things slowly start to make sense. Is Light the faceless killer Kira, or is the greatest detective in the world wrong for once and Kira is someone else entirely?
