What does a great mage need in a familiar? A convenient resource? A fierce guardian? A loyal friend? — What does a troubled young zero need to become a great person? Power? Pride? Validation? — Void only knows that some answers can never be so simple. In a world where numbers and effort are everything, perhaps one Louise the Zero can discover just what it is that she truly needs.

Kirigaya Kazuto, Kirito, Beater of SAO, and now a Spriggan in ALfheim online, is fighting to save the love of his life from a fate worse than death. Louise De La Valliere, third daughter of the Valliere family, and student of the Tristain Academy is fighting to prove herself. Two worlds collide as a summon goes wrong and Tristain finds itself with some very confused new residents.

Louise gets bodily reverse-summoned into Sword Art Online, just as Kayaba's Forced Teleportation gathers all 10,000 players for his announcement. The Death Game is on.
