Nakagami Kasuga

Akihito’s non-blood-related sister. She’s extremely intelligent and talented in music. So much so that she went to Vienne to study music. She moves along her own pace, which is practically as fast as a bullet train. Energetic and crazy 24/7. Cheerful and naive, she doesn’t seem to understand the meaning of restrictions. She likes Akihito which to her equals to marrying Akihito.
