Each Champion in Shelter 69 has her own backstory and character arc that takes place throughout the game. However, apart from the main story told via the Campaign missions, much of the game can be completed or unlocked in any order. Below you can find a list of the Champions in Shelter 69, with a guide to how their personal story all fits together. This is simply a list of the order in which missions, flirts, H-scenes and events should be completed or read for the Champion's story. It should not include any summaries or spoilers about the character's storyline.

Tess's initial storyline is closely tied to her relationship with Samantha. As a result it is best to follow the guide above for Samantha in order to read Tess's story as well.
