[Name] Iruka Suma [Age] 20 [Height] 164cm

A native of Hyogo Prefecture who speaks with a regional drawl. A second-year female station attendant at Umeda Station working for Han○ Railway. Usually a quiet, cool beauty. However, if someone is rude to her, her language becomes incredibly foul. While considered a bit of a problem child by management, she is very kind to families and those who follow the rules. She's popular with children due to her hidden cuteness; she'll even let women and children take photos with her on the platform. She has zero tolerance for rule-breaking train spotters—she'll kick, hit, and scream at them. She chases down gropers and won't forgive voyeurs. Her sprinting speed on the platform has made her a local legend at Umeda Station. Among train enthusiasts, she's a bit of an idol... some even want to be kicked by her. When she joined, a senior joked about her name, saying, "'Suma Iruka' (Smile-ka)? With that grumpy face, you look like you hate smiling." She doesn't have a good impression of men and avoids talking to them; even colleagues and bosses find her unapproachable. She tries to be as polite as possible to customers, but has been asked, "Are you angry?" before. Legend has it she once flying-kicked a train spotter who crossed the yellow line back onto the platform.

Typical train enthusiasts (A, B, C, D, E). Generally dangerous in their desperation to get the shot, causing trouble by hogging space or using stepladders on the platform. They usually mumble, making them seem harmless, but they can become overbearing when dealing with girls. A few are actually decent people.

[Name] Yoji Tajima [Age] 51 A man who represents the worst of toxic train spotters. He claims to know many railway employees but can never name them. He mutters complaints under his breath at tough-looking staff, but is incredibly high-handed toward staff who look weak, young, or female. Self-centered and only cares about himself. He says things to Iruka like, "Don't defy me, you're just a female."

[Name] Ichika Yaba [Age] 29 A seemingly well-mannered train spotter. He asks staff things like "Is it okay to shoot here?" and greets them properly. Staff who recognize him consider him a "good" enthusiast.
