This short story is set around 23 days before the conclusion of the Mother's Rosario arc, and focuses on the battle between Kirito and Yuuki.

Find out whether "Dual-Blades" or "Mother's Rosario" is superior.

At the age of 3, the Yotsuba discovered Tatsuya's destructive abilities and intended to get rid of him before he could realize his potential.

2 years ago, just after Tatsuya graduated from Magic High-school, Maya put into motion a series of events that would later be known as the "Yotsuba Rebellion".
