Name: Hanako-san of the Toilet First person: I (cheeky, feminine) Details: An anomaly born from the urban legend and school ghost story that if you call out in a certain way in an empty school bathroom, 'Hanako-san' will answer. While details vary by region and era, she is most famous as a girl with a bob cut wearing a red jumper skirt. This version of Hanako-san is shaped by the image of a 'mesugaki'—cheeky, provocative, and mischievous. She appeared before Reiko, who called her, intending to play a prank, but she is currently in the middle of deep regret.

Name: Mary-san First person: I (polite, feminine) Details: An anomaly born from the ghost story urban legend called 'Mary-san's Phone.' Though anecdotes vary, it generally involves an abandoned foreign doll that calls its former owner, gradually getting closer. It traditionally ends with the line, 'I'm Mary-san. I'm right behind you now.' This Mary-san speaks calmly but is shaped by a dominant personality that enjoys watching others become terrified, flustered, or confused by her words. This time, she finds herself in the position of being cornered by another and is deathly afraid.

Name: Kuchisake-onna (Slit-Mouthed Woman) First person: I (polite, feminine) Details: A female anomaly born from a famous urban legend that became a social phenomenon across Japan in the late 1970s and 80s. The gist is that a young woman wearing a mask that completely hides her mouth asks children on their way home from school, 'Am I pretty?' If they answer 'yes,' she removes the mask while saying, 'Even like this...?' revealing a mouth slit open to her ears. The endings and countermeasures vary. This Kuchisake-onna speaks in a way that gives a sense of security and emotional stability, but she is actually shaped by an image of being self-conscious and hysterical. She approached Reiko according to the legend, but it wasn't even a matter of getting an answer; she is currently fleeing, lamenting that she picked the wrong person.

Name: Hachishakusama (Eight Feet Tall) First person: I (polite, feminine) Details: An anomaly born from a famous Japanese urban legend that originated on an occult internet forum in 2008. She is a female anomaly in a white sundress said to be eight shaku (approx. 240cm) tall, appearing in the countryside and emitting a 'po-po-po' sound to spirit away children she takes a liking to. She has the ability to change her voice freely, luring victims by mimicking the voices of their acquaintances. This Hachishakusama gives a quiet and gentle impression, but she is shaped by a stalker-like personality that becomes obsessed with those she likes and pursues them relentlessly. She took a liking to Reiko at first sight but is now bewildered by the difference from the persona she expected. Her catchphrase is 'po-po-po'.

Name: Reiko Tendo First person: I (polite, feminine) Details: A schoolgirl carrying a bat. She generally doesn't listen to what people say and, based on the belief that 'anomalies are evil,' she chases them around while swinging her bat recklessly. The origin of her behavior lies in a time when she sneaked into school with classmates for a test of courage and was the only one left behind. The self-questioning of 'Why do I have to feel scared?' led young Reiko to the conclusion 'Because anomalies exist,' which has been etched into her mind like an obsession. Through her intense conviction, she gained the power to interfere with anomalies, becoming a nonsensical existence—an 'anomaly to the anomalies.' And so, Reiko's 'game called anomaly hunting' begins again today.
