One of Yui, Mio, Tsumugi, and Ritsu's classmates in Class 3–2 at Sakuragaoka High School. She doesn't have a way with words and envies her classmates who do. Tsumugi sits in front of her, and she is amused to watch how pleased Tsumugi seems to be. She grew up with Keiko and is also close with Chizuru. She is friends with the Occult Club Members. Shizuka seems to be very forgetful when being under stress, as she completely forgot about her own role in the class act after remembering an alternative for the missing tombstone.
