Mia Luna Tearmoon: The relationship between Mia and Sion is a complicated one, with him being the hero who issued an execution upon the tyrannical fiend, Mia, in the first timeline and her still holding a (minor) grudge against him in the second timeline. In the first timeline, Sion was disgusted at Mia's behavior while Mia believed that they were meant to be together. He always avoided her to look for Tiona and was extremely annoyed at Mia's persistent. Although he supported Mia's execution, he came to regret it later in older years.

In the second timeline, Sion meets Mia when he saw her defending Tiona from the bullies. Moved by her action, he wishes that the years he will spend in Saint-Noel will be worthy of his time if someone like Mia is there. He asks her to be his dance partner, but Mia goes off and claims Abel to be her partner when Abel is being confronted by Gain". Sion eventually falls in love with Mia and he finds ways to make her shift her attention at him whenever she flirts with Abel. Such time is when Mia only notices Abel at Rafina's afternoon tea party, Sion pretends to sulk so she can comforts him with pleasing words. He is also a teaser. Though, there are times when Sion genuinely feels hurt when he sees that Mia only cares about Abel.

Sion starts calling Mia by her name (dropping the princess title, just Mia) and vice versa half-way into Volume 2 of the light novel.

Tiona Rudolvon: A friend of Sion. In the first timeline, he and Tiona were the prime people who issued Mia's execution. In the second timeline, they respect each other as friends and nothing more.
