Singing Doesn't Kill Zombies (Vocaloid FanFic)

Miku Hatsune's father is an unemployed man who enjoys target practice.
Her childhood friend, Kaito Shion, is always mooching on her parent's equipment, and her life isn't any better with two baseball-loving blond brats always showing up uninvited for dinner.
Her home is an old, dank place, and her life is slowly crumbling.
Could it get any worse? Maybe, just maybe.
When the dead begin pressing their palms against her doors and her father is brutally torn apart by neighbour, the bodies begin piling up and Miku realizes that it's time to take the gun in her hands. Target shooting begins now, and the targets are the dead.
