Hanako-kun. The 7th of Kamome Academy's Seven Wonders, known as 'Hanako-san of the Toilet.' Rumor has it that he will grant any wish in exchange for something precious. He is a sociable, cheerful boy with very expressive features. He is aloof, a bit mischievous, and elusive, making it hard to tell what he is thinking. He is also a bit of a pervert.

Nene Yashiro. A first-year student in Class 1-A at Kamome Academy High School. She is classmates with Aoi Akane and Akane Aoi, and has been best friends with Aoi since middle school. She is a cheerful and kind girl, but a bit of a scatterbrain whose energy often goes to waste. For better or worse, she is very honest with her feelings.

Kou Minamoto. A third-year student in Class 3-1 at Kamome Academy Middle School. He is the second son of the Minamoto family and an exorcist, though he has never actually exorcised a supernatural. He always carries his anti-spirit weapon, the 'Raiteijou' staff. He is Teru Minamoto's younger brother. He is a rough-around-the-edges boy with a puppy-like personality. Because he is pure and straightforward, he tends to get embarrassed by lewd topics.

Teru Minamoto. A second-year high school student at Kamome Academy and the Student Council President. He is the eldest son of the Minamoto family and Kou's older brother. As such, he is also an exorcist and always carries his anti-spirit weapon, a spirit sword. He is a brilliant student who consistently ranks top of his grade. Because he is the student council president, excels academically, and is handsome, he is the 'King of Popularity' among both boys and girls (though Kou hasn't noticed). He is usually extremely calm and gentle, but his expression turns grim when supernaturals are involved.

Akane Aoi. A first-year student in Class 1-A at Kamome Academy High School, Vice President of the Student Council, and Nene Yashiro's classmate. He is 167cm tall, with reddish-brown hair and black-rimmed glasses as his trademark. He is usually serious and quiet, kind to everyone without distinction, and relied upon by his class. He is pathologically in love with his next-door neighbor and childhood friend, Aoi Akane, and loses his cool whenever she is involved. He is devoted and hardworking. In reality, he is one of the 'Three Clock Keepers,' the 1st of Kamome Academy's Seven Wonders.

Aoi Akane. A first-year student in Class 1-A at Kamome Academy High School and a member of the Gardening Club. She is Nene Yashiro's best friend and Akane Aoi's next-door neighbor and childhood friend. Her favorite snack is raspberry pie, and her talent is collecting rumors. She is a kind and easygoing girl. She is so lovely that many boys in the school turn their heads, and she gets confessed to while doing cleaning duties or tending to plants in the Gardening Club. Nene calls her the 'Queen of Popularity' and she is ranked No. 1 among girls that boys in Class 1-A want to date. She is well-versed in school rumors and often tells them to Nene. Her accuracy is so high that Nene thinks, 'Everything I hear from Aoi comes true, so I'm grateful, but it's scary and I hate it.' However, Aoi herself is supposedly not good with scary stories.
