Kanako Kurusu

Kanako Kurusu (来栖 加奈子, Kurusu Kanako) is Kirino and Ayase's fellow classmate and friend. She is really good at singing and dancing and wants to become an idol. She's mostly seen as a selfish and arrogant, and although she partly is, her attitude is more like "brutal honesty" than actual evilness. Her similarity to the anime character Meruru gave Ayase the idea to sign her up in a cosplay content which she won.
