My Peaceful Life Will Eventually Be Shattered by the Band Girls

My name is Nakano Miumi. I'm 16 years old. I live in a villa district, I'm unmarried, and I have five biological older sisters at home... I long for a quiet life. If an enemy keeps me up at night, I'll make him understand the terror of Calamity. Calamity has chosen my Stand, Wonder of You, as the invincible pinnacle. The power of my Stand, the power of Calamity! It's been proven: no one can surpass me. I'll finally live the peaceful life I've always dreamed of! But for some reason, I feel like someone is going to get in my way. My childhood friend, whom I haven't seen in ages, always manages to insert herself into my life through one coincidence or another. Her name is Nagasaki Soyo. My lover Mutsumi has awakened Mortis Requiem, which can copy every Stand ability. She's the only one who can oppose my Calamity. The girl who lost to me at a childhood piano contest not only took up snake-keeping, but can also make people feel a snake's terror. The little girl who likes picking up rocks by the roadside always has a white cloud over her head. The two guitarists who ran away have Stands of the same type! Why are all the band girls Stand users?

Yoshiro Miumi (Nakano Miumi): I just want to live a peaceful life.

Father Moci (Mortis): Miumi is destined for heaven. And the ones escorting you to heaven are the band girls!
