For her role in saving everyone from the horde of monsters with her purification magic, Sei is rewarded by being teased by Grand Magus Drewes, much to Albert’s displeasure. Upon returning to the palace, word of her great saintly deeds precedes her, and she’s even more of a celebrity with the nobles.
I wouldn’t be surprised if Prince Kyle specifically waited until Sei returned in order to stage his spat in the courtyard with Elizabeth, who both wants to be a friend to both Sei and Aira. Kyle lays it on rather thick, calling Sei an “impostor” and “most definitely not the Saint”, making things even more uncomfortable for poor Aira.
Liz, unaware that Kyle is carrying out a ploy, takes him to task for his foolishness, but then both she and Aira spot Sei, and Kyle takes aim, pretending not to know who she is and even trying to put his hand on her. Albert comes out of nowhere to prevent that.
Drewes, who slinked off, returns with the king himself and his retainers, and takes Kyle to task for spreading fake news. Kyle continues to maintain that despite Aira having no accomplishments of note, she’s still the only person he summoned. The king orders them to continue this discussion in private.
There, Kyle bears all, admitting he was intentionally acting like a boorish lout so that all the heat from the public would fall on him, while Aira would be seen as a victim in his craven schemes. After learning he played the fool for Aira’s sake, Liz is no longer angry at her fiancé, and in fact seems to have come to admire him even more, while lamenting how awkward he is.
As for Liz, Aira is left in her care, and she arranges a tea party so that Sei, who is now officially recognized by all as the Saint, can finally meet Aira, and vice-versa. It’s a little awkward at first (due to the age difference, among other things), but Aira soon learns that Sei is a gentle, kind person who is eager to spend more time with her.
She and Liz also suggest that if she wants to continue her magical studies, she should join the Royal Magi Assembly. Considering how long Sei and Aira were kept apart, this first meeting has a very understated, almost anticlimactic quality. And maybe that’s for the best: one thing Sei and Aira have in common (besides their homeworld) is a general distaste of the limelight. A laid-back tea party was the perfect place to begin their friendship in earnest.
The king, striking an Ikari Gendo pose, consults with his chief of staff about the region in most need of assistance against the scourge of monsters and miasma: Klausner’s Domain, AKA “The Alchemist’s Holy Land”, the kingdom’s primary source of medicinal herbs.
When Sei learns Albert and his knights will be headed to Klausner’s, she volunteers to come along, surprising her director who assumed Sei would want to stay put at the institute and was preparing excuses for her. Albert says Sei’s safety is paramount, but what’s a safer place for her—or him—than by each other’s sides?
