Sarai

One of the seven High Priestesses of Ivala, she has her residence in the Cathedral of Yhilin. She is the High Priestess of the Lost, who represents the territory lost to the Incubus King in his initial invasion.

Though she has an extremely pious outer appearance, Sarai is foul-mouthed and irreverent in private with those she trusts. Her religious philosophy is that Ivala is concerned with broad issues of justice, not "pious bullshit". As a priestess she must remain celibate, which is an ongoing source of frustration.

At some point prior to the start of the game, she worked with Simon on Church business and they not only established a good teamwork dynamic, but a personal friendship, if the interchanges are any evidence. It apparently was successful but resulted in a large number of casualties, which caused Simon to break off the arrangement and return to working with Chosen, and were personal baggage on Simon's conscience. It's unknown if this incident is related to Commander Geoff's comments in their tense meeting in the border.

Story
Once the party has reached Yhilin, Sarai provides assistance a number of times due to her personal relationship with Simon.

Given that she has relationship points and actively seems to want to jump Simon's bones, she's a very likely future harem member, though first she will need to circumvent the restrictive spells or even follow Carina's example and leave the Church. (The latter is unlikely since she worked so long to gain power in the Church for the greater good.)

Relationship points
Maximum affection is 100, at which you can have a conversation with the harem girl that will lock her affection there.

Sarai is in favor of justice and effective altruism, but since she's not in the party she doesn't gain points from things she isn't present for and doesn't hear about secondhand. She's also grateful for conversation with and stories from people who aren't into "pious bullshit", so talk to her whenever you have the chance.
