Aka★Pro!!! ~Akarui San Shimai Project!~

The Akei siblings lead a cheerful and lighthearted life filled with daily amusement. Hotaru, the oldest, is a college student known for her absentminded nature and tendency to daydream. Hikari, the middle sister, is a junior high student whose energetic personality helps maintain the family's dynamic. Akari, the youngest and still in elementary school, is unexpectedly mature and often serves as the level-headed one. The family relocates to a spacious condominium, where their everyday experiences unfold in a series of simple, humorous moments.
