Miyakoe is also one of the characters who had chosen the prestigious high school to reinvent her own image and start a new high school life. She was often ignored and overlooked in middle school, thus always ending up alone and being unable to make friends with anyone.
She is interested in all things occult and mysterious and is adamant to create a Mystery Club in her new high school, automatically recruiting an unwilling Yuta and an indifferent Touto as members. She also adds Kyou to the group later as their 'informant'. She's usually kind and friendly but can get overly enthusiastic and scary when it comes to mysteries and high school myths. She's usually seen with Yuta and Touto and ironically, doesn't believe Touto whenever he says he has experienced something paranormal.
