S'yne Lokk/Relationships

Naofumi Iwatani
Naofumi and S'yne first met at the Zeltoble Coliseum, where they both fought and S'yne warned Naofumi that he must become stronger or he would die.

They met again shortly after, when S'yne suddenly appeared in Naofumi's village, where she asked if she could stay and work for him, a request that Naofumi initially refused. But after S'yne saved him and him rest of his group from otherworldly invaders, he agreed to let her stay in her village and work for him.

Since then, S'yne has proven to be extremely loyal to Naofumi by accompanying him almost everywhere as if she were his shadow.

After S'yne managed to speak again without any interference in her voice and S'yne's Sister revealed part of S'yne's past to Naofumi, he has tried to get her to tell him what she knows. Which S'yne flatly rejects, as she believes that anyone she tells will die.

It has been hinted on a few occasions that S'yne may have romantic feelings for Naofumi.

Ren Amaki
She had little interaction with Ren but was shocked at his weakness.

Motoyasu Kitamura
S'yne sees Motoyasu as a rival in terms of sewing skill. In one of the untranslated side stories, it is shown that the two of them often clash in their opinions about what kind of clothing suits the Filo Rials of Naofumi's village best.

Vassal Heroes
Information to be added later on.

S'yne's Sister
S'yne hates her own sister after she joined the vanguard of the waves, and wants to kill her. S'yne's Sister told Naofumi that she can't explain all of S'yne's secrets because S'yne would become more careless in her revenge.

Otherworld Invaders
S'yne has a strong hatred towards the Other Worlders for destroying her world. She had declared them to be her arch-enemies.
