Kingdom of Sunkland

 * Abram Sol Sunkland: The king of Sunkland and Sion's father whom he respects.
 * Keithwood: Sion's trusted bodyguard and valet. It is stated that they grew up together like siblings.

Saint-Noel Academy

 * Mia Luna Tearmoon: The relationship between Mia and Sion in the first timeline was a bitter one, with him being the hero who issued an execution upon the tyrannical fiend, Mia. In the first timeline, Sion was disgusted at Mia's behavior while Mia believed that they were meant to be together. The prince always avoided Mia to look for Tiona and was extremely annoyed at her persistent. He didn't spare Mia after Ludwig pleaded for her life, but he came to regret it later. In the second timeline, Sion is in love with Mia and he finds himself charmed by her wisdom and intelligence. When he sees Mia works hard to change her empire, Sion is inspired to do the same. It is unknown to him that Mia held a grudge against him, but that grudge eventually faded. Mia sees Sion as a dear friend, and their sweet friendship is something Mia never dream having in the previous timeline. They trust each other and has rescued one another in several occasions. After Remno Revolution, both Mia and Sion dropped their royal titles and address each other by their first names. Sion likes to tease Mia to get a reaction out of her and he initiates his moves on her such as being the first person she dances with at her birthday ball. Thanks to Tiona's motivating words, Sion begins to step up his game for Mia. Even though he is in love with Mia, Sion is willing to choose Sunkland and his family over the princess's affection, knowing that he couldn't throw away his duty as its future king to marry Mia in Tearmoon.
 * Tiona Rudolvon: In the first timeline, he and Tiona were the prime figures who had Mia executed. It is still unknown if Sion loved Tiona in the previous timeline because Sion put Mia to death for Tiona, and in Tiona's "dreams", they were intimate in their letters and she was also in love with him. In the current timeline, Tiona encourages Sion to make a move on Mia when he still can and he considers it.
 * Abel Remno: Sion's friend and rival. They spar with each other when there is a chance, such as during the Swordsmanship Tournament, Remno Revolution, or in their free time alone. Throughout the series, the two friends have a casual relationship and both threw away their princely titles and address each other simply by their first names. Abel is also someone whom Sion is jealous of for Mia's attention and affection.

Abilities

 * Swordsmanship: Sion is a prodigy when it comes to handling swords and he has been trained to use one since he was a child. His skills are in pars with the adults.
 * Horsemanship: Sion can ride a horse and has been using horses in Horsemanship Club with Abel.
 * Dancing: He is good at dancing, simply because Sion is someone who is perfect in every way.
 * Cooking: He never cooked before, but in one try, he managed to make delicious sandwiches that are better than the girls'.

Trivia

 * Sion is 15 years old in Volume 8 and here is that evident. Sion's birthday is still unknown to readers, but in Volume 9 when Tiona asked him when was his birthday, he replied "10 days ago". The annual season in Volume 8-9 is summer, either from Late July till Mid-August. Mia's birthday is in the winter, so that makes Sion a few months older. Plus, Saint-Noel students attend school in spring the year they turn 13, so that makes Sion already 12 in volume 1 and turning 13 in volume 2.
 * Sion's Drama CD voice actor is Horie Shun, who is known for his roles as Aether from Genshin Impact, Schain Zagan Analeit from I'm a Spider, So What?, and Kinoshita Kazuya from Rent a Girlfriend.
