HalO part two. Asuna and Kirito have been Reunited and Prince Wales still draws breath as war with Albion Looms on the horizon. Meanwhile Louise Valliere continues her search for the lost Pixies of Tarbes Garden only to be met with set backs and complications. They will all soon discover that they have more to fear than just Albion, and that there are worse monsters than Zombies.

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.
