Aoi and Akaba

Y/n is the younger sister of Aiga. She's been trapped in her brother's shadow for as long as she could remember. But when she makes her own bey, she sets out to make a name for herself, hoping to even one day surpass Valt Aoi, the boy with consecutive wins for two years. But she can't do it alone. She needs help from friends - friends she doesn't have.
