Melty Q Melromarc/Relationships

Naofumi Iwatani
Melty's relationship with Naofumi is initially strained by his clashes with her father Aultcray. They start off on neutral footing, but it soon becomes alienated by his dark disposition, which only gets worse when he learns of her royal lineage. The reason for her return was to make amends with the Shield Hero and her father but has failed twice due to the former's obstinate refusal.

When Naofumi stands up to openly mock Aultcray, Melty approaches him to demand an apology and start a serious discussion with her father, as she was afraid of the consequences of the sourness, resulting in her father landing the wrath of her mother. However, she slowly starts changing her mind about Naofumi when he saves her life against an attempt from the Cult of the Three Heroes; henceforth, under the Shield's protection, their relationship finally begins to thaw, although she is still terrified of his harbored resentment toward her family. She later asks Naofumi to start addressing her by given name instead of her royal title (customarily implying a more intimate connection).

Naofumi ultimately protects Melty from her sister, the Cult, and the other Heroes (who think she's been brainwashed by him when, ironically, they are the ones who've been brainwashed by praise, propaganda, Malty, the Cult of Three Heroes and Aultcray's direct lies). He has a short but significant adventure with her until his name is cleared by her mother. Melty, alongside Raphtalia and Filo, objects when her sister calls Naofumi "ugly," and is noted by her mother to actually have a chance at marrying the man (which has a lot of political advantages that the Queen eagerly tries to force).

Motoyasu Kitamura
Motoyasu tried to supposedly save Melty from the "evil" Naofumi and refused to listen to Melty, believing her to be brainwashed. After going through a lot and seeing Motoyasu's approach of Filo, Melty snapped enough to attack him. After Naofumi's name was cleared, the two rarely interact, but she expressed displeasure towards him, such as when he went on a rampage with his weapon's cursed form.

Aultcray Melromarc XXXII
Melty cares for Aultcracy, as he is her father, though she couldn't stand his fawning behavior towards her older sister. She also doubts all his past deeds told by her mother. Fearing her mother's wrath towards him, Melty rushes to mend his relationship with the Shield Hero but fails due to the Hero's constant refusal. Though, she later sides with Naofumi when the Church attempts against her life.

Raphtalia
The two got along when they first met. Although Naofumi starts displaying his hostility towards the princess after learning of her identity, Raphtalia was more lenient towards Melty as she claimed they did travel together a bit. However, this didn't stop Raphtalia on somewhat complying with Naofumi's actions and decisions to not be involve with her.

The two became close comrades when Melty joins her, Naofumi, and Filo in their quest against Church of the Three Heroes who were conspiring with Malty against Naofumi with more false charges. When Melty starts showing more intimate attachment towards Naofumi (like asking to be called by her first name), Raphtalia becomes uncomfortable on how close the two were getting. Regardless, their time together has made Raphtalia and Melty share a strong mutual trust.

Filo
She considers Filo her best friend and cried upon being separated from her the first time. She is also a fan of Filo's species and longed to meet the Filolial Queen, a dream which came true through Filo's existence. Naofumi's trust on Melty is completely based on Filo's good grasp of character placing complete trust in her.

Eclair Seaetto
Melty and Eclair seem to have compatible personalities. They both work for Naofumi's territory. While Eclair is the deputy governor, Melty manages everything else while Naofumi takes care of the villagers. Melty also sees the flaws of Eclair's approach in rebuilding the Saeatto territory but prefers to refrain herself from commenting, as she could imagine that this could spark unnecessary bad blood between them.

Malty S Melromarc
Though Malty had attempted to kill her to ensure that she could have the throne for herself, Melty was unhappy about her impending execution, and was grateful when Naofumi decided to spare her.
