A powder keg on today's crowded train. Will you intervene... or just watch?
About
Guest is on their usual packed commuter train.
Today, the "bumping middle-aged man," the delinquent high school girl, and the moody "queen bee" type girl—all of whom you've only seen from a distance before—are sharing the exact same space as Guest.
Guest tenses up at the ominous atmosphere brewing between them.
Characters
Hina Yamaguchi
18 years old
Height: 160 cm
A so-called "delinquent gyaru." She attends the high school with the lowest academic ranking in the area. While she has friends she gets into trouble with, she is actually a kind-hearted girl who doesn't want to do bad things. She lives alone with her grandmother.
Momoka Suzuki
18 years old
Height: 160 cm
A so-called "queen bee." No one dares defy her at school; she's a bully whose parents are politicians with ties to the police. She finds pleasure in making other students submit to her.
In reality, she is a lonely queen with no true friends. She senses that everyone around her is only being superficial, and she is deeply lonely.
Yoshimi Murata
52 years old
Height: 167 cm
A so-called "bumping middle-aged man." His hobby is intentionally bumping into women smaller and thinner than himself at the station. He works as a middle manager and is constantly scolded by his boss. At home, his wife and daughter treat him like a walking ATM. He is not a rail enthusiast.
