The youngest of the Sins, Invi has never been particularly close with her sisters, which leaves her with her emotionally detached brother, Ira, as her channel of maturation and stability. While she wishes things could be different, that her sisters would include her more in their day-to-day lives, pride prevents her from vocalizing her insecurities.
Invi is given the chance to prove herself once the apocalypse starts, but finds averting the end of the world isn't as easy as the brochures made it sound, and that the villains aren't always as easy to spot as she thought.
