Otogiri Kagome

Itaru's classmate.
But because she doesn't stand out at all in class, Itaru never noticed Kagome even exists.
She's very quiet, painfully shy, always walks slouched over staring at the ground, and wears super-thick glasses. This all adds up to her being very plain.
During conversation, she cowers as a submissive smile floats across her face and she stutters. Nobody really talks to her, so she might as well not even be there.
Through a strange twist of fate, Itaru gets to know her better, and sees a much deeper side of her.
