Landlady of Narutaki Sou, she shares the same high school as Tamami. Her personality shifts depending on her emotions, reverting to her original one after sleeping or fainting. Each persona sports a unique hairstyle with bells and distinct eye colors. Kozue's eyes are bluish-green. Ryūshi is her second cousin. She is incredibly kind and enjoys umeboshi like all her personalities. In the manga, she starts dating Ryūshi from chapter 39, and by the epilogue, they seem married with four kids, likely representing her other personalities. At the series' start, she is sixteen, born on December 22.
Saki Akasaka
Saki has red eyes and a tough demeanor, wearing her hair in a ponytail. Despite this, she genuinely cares for others, though she's embarrassed to admit it. She emerges when Kozue feels surprised or angry. Saki can't tolerate alcohol except umeshu (in the manga), and in the anime, even the smell makes her faint. She also fears butterflies.
Nanako Kanazawa
Nanako behaves like a six-year-old with yellow eyes and two "antennae" in her hair. She appears when Kozue feels embarrassed. After becoming "Shiny," she usually acts better. Nanako is the only personality given an actual age; the rest remain unknown but assumed to match Kozue’s.
Chiyuri Midorikawa
Chiyuri loves cosplay and forces others into it if they resist. She shows up when Kozue is clumsy or scared. Sporting a large side ponytail and green eyes, Chiyuri makes Tamami her assistant, calling her "my partner." Tamami reciprocates with "my sweetheart," supplying embarrassing photo opportunities. "Correct!" is her catchphrase.
Natsume Konno
Natsume is shy and initially avoided speaking. She excels at sleight of hand and card tricks. The first time she spoke was teaching Ryushi one. Happy moments make flowers sprout from her head, parodying her first magic trick. With blue eyes and high pigtails, she ends sentences with "...kamo," meaning "maybe" or "I think." She appears when Kozue is saddened.
