In Train45, each important character has a different affection path, chapter limit, and event unlock condition. In this guide, I explain how I progress Reina, Mai, Konial, Butler, and Pazuzu without going outside the main characters information.
Character Affection and Events Guide
In this Train45 character guide, I cover the main partners and story characters, how their affection works, when they become available, and which events are connected to them.
Reina

Reina is an office lady and one of the main partners in Train45. Her maximum affection level is Lv8, but her progress is limited by the current chapter.
Successful exploration gives Reina affection experience. However, each affection level only increases after I watch the main H event for that level.
I talk to Reina in the starting car to unlock new dialogue at each affection level. Later dialogues give more progress. Her Lv5 Hot Spring dialogue and Lv6 Cooking dialogue also unlock Car Navigation.
- Maximum affection: Lv8
- Progress is limited by chapter
- 7 main scenes
- Anomaly scenes: Hot Spring, Puppy, Milking, Swimsuit
Mai

Mai is a gyaru and one of the main partners in Train45. Like Reina, her maximum affection level is Lv8, and her progress is also limited by chapter.
Mai’s affection works the same way as Reina’s. Exploration gives affection experience, but before each level increase, I need to watch the related main H event.
I can also talk to Mai in the starting car to unlock her affection dialogues. Her Lv5 Cat dialogue and Lv6 Roulette dialogue unlock Car Navigation.
- Maximum affection: Lv8
- Progress is limited by chapter
- 8 main scenes
- Anomaly scenes: Cat, Bunny Girl, Stuck-in-Door
Konial

Konial is the demon station chief. She becomes tied to the starting car in Chapter 6, and her maximum affection level is Lv3.
To raise Konial’s affection in Chapter 6, I equip the shop item Copper Bracelet. After that, each successful exploration gives +10 Konial affection.
The important downside is that Car Navigation is disabled while the Copper Bracelet is equipped.
- Available from Chapter 6
- Maximum affection: Lv3
- Requires Copper Bracelet for affection gain
- H scenes unlock in Chapter 6
Butler

Butler is a monster who takes human form after Chapter 4. His maximum affection level is Lv2.
Starting from Chapter 4, I raise Butler’s affection by opening chests in cars where chests appear. Each chest gives Butler affection, around +4.
- Human form appears after Chapter 4
- Maximum affection: Lv2
- Affection comes from opening chests
- H scenes unlock in Chapter 5
Pazuzu

Pazuzu is an angel who wants to return causality to the correct path. I first meet Pazuzu in Chapter 3, Car 8.
Pazuzu’s connected scenes include Tentacle, a story scene, and the Mirror anomaly terminus. These open in Chapter 5.
- First appears in Chapter 3, Car 8
- Connected to causality and the story route
- Scenes unlock in Chapter 5
- Related content: Tentacle, story scene, Mirror anomaly terminus
