This is the story about how a perceptive girl with an extremely good talent for singing takes the tiniest thread of a chance that she gets, which leads to her achieving her ultimate dream...but with a lot of difficult times, and frayed relationships along the way. Despite this, her friendships only grow, as even the hardest times - and the most extraordinary experiences - can make you bump into those who become the people closest to your heart.

Based on Sword Art Online~ One day, as a group of girls meet up to play Osu! together, they are sucked into the virtual world and transformed into Japanese vocaloids. They are stuck there unless they can pass the extreme beatmaps. They are given five lives. If they die completely, they remain 'dead', unless one of them can pass the last beatmap. ~Co-written with violette_cupcake
