Kugayama Konoka♀

Masanobu's little sister who wears her otaku heart proudly. Really mischievous. She takes delight in teasing her friends, particularly Hinano. Konoka struggles with a weak memory, where her episodic recollections fade away within three days. To combat this, she diligently keeps records of her experiences through detailed notes and drawings, ensuring that precious memories aren't lost forever. Konoka's affection for her brother is unwavering. Their separation for years was a unique method to train her memory and prevent excessive reliance on records, but they stayed connected through regular contact.
