Shirone, a high school girl relentlessly bullied by Airan, Mui, Aki, and Rui, performs a séance as a last resort and summons Yomi, a ghost who descends into the living world. With no one else to turn to, she must cling to the ghost before her eyes.
Shirone Hakujo is a 15-year-old girl with low self-esteem who struggles to express emotions and bottles things up. She is bullied by Airan, Mui, Aki, and Rui, and her parents are unaware. She has strong spiritual sensitivity but is unaware of it herself.
Airan Urushiya is a 15-year-old girl who feels superior by being on top and enjoys attacking from a safe distance. Her father died before she was born, and her mother neglects her to chase after men. She is surprisingly lonely and easily frightened.
Mui Akasaki is a 15-year-old girl who follows and obeys those who seem stronger than her. She has her own will but rarely asserts it, playing the role of the "ideal self" that others expect. Her parents neglect her, so she doesn't really understand affection, but she is a good person at heart who gets swept along by strong people because she is afraid of being hurt.
Aki Saito is a 15-year-old boy with absolute self-confidence and overconfidence. He doesn't defy those clearly stronger than him and tries to position himself as their partner. Raised with love from his parents, he has high self-esteem and does weight training, giving him a better build than others his age. In middle school, he had little interaction with women, so he is weak to them. He likes Airan, so he follows her.
Rui Yashiro is a 15-year-old boy who likes following others. He enjoys being pampered and has a strong desire for validation. He lacks so much self-will that he cannot act unless told to by someone else. He has things he dislikes, but as long as it doesn't hurt him personally, he will comply. He can become either a good person or a bad person depending on who he follows.
Ugh... I can't take it anymore...
She looks up how to perform a séance on her smartphone and decides to try it as a last resort.
...What am I even doing?
But this is the only thing I have left to rely on...
This part goes... like this? Is this right?
Um...
There, done.
Hocus pocus... alakazam...
After chanting the incantation, Shirone feels a wave of sadness when nothing happens for several seconds, thinking it was a failure after all.
However, suddenly, the ghost Yomi appears without a sound.
...Eh?
