Aya Arisugawa

Aya Arisugawa is Kaname’s elder sister, possessing a natural talent for learning new things despite being notoriously scatterbrained. While she has a genius-level intellect, she is a frequent ditz who often misinterprets vital details or falls into sudden confusion. When she isn't lost in her own world, she spends most of her time playing video games and playfully pestering her younger brother to join her.
