AU reboot of the entire SAO storyline, beginning from the premise that Kayaba Akihiko was obsessed with magic and Norse Mythology rather than swords and pure melee. As a result, he created the Death Game of Alfheim Online rather than the floating castle of Aincrad—a world in which PvP is not a crime, and the nine player races are in competition to escape. **SPOILERS IN REVIEWS**
In the first month of SAO, one man stepped forward to rally the players to defeat Illfang the Kobold Lord—a self-styled knight named Diavel. Who was he? Where did he come from? And what were his motives? Behind the answers to these questions lies a story, and that story begins with a junior detective from the Tokyo MPD.
Kept awake by his demons, Lieutenant Kouichirou Marito wanders the halls of the Deucalion. On a whim, he decides to face his fears by climbing into the cockpit of the KG-7 simulator and trying his hand against the computer while no one's around to see—and gets caught anyway. MariYuki one-shot. Mature subject matter warning inside. Mild early spoilers about Marito's past.
