Raphtalia/Relationships

Naofumi Iwatani
Initially, she was scared of Naofumi because of his sour demeanor and her horrible experiences with previous slave owners. She becomes surprise on how kindly Naofumi treats her such as properly feeding her, giving her medicine, comforting her whenever she suffered traumatic experiences from her past, and fairly attending to her overall needs. After learning who he was and that he was fighting the Waves, she decided to give her all for him. Their relationship slowly improves that after couple of weeks, when she quickly grows up physically through level grinding, she becomes more extrovert towards him.

Her devotion towards him becomes so strong that she considers herself as Naofumi's sword and will react negatively towards anyone who insults him. This loyalty is shown again where she returns to Naofumi's side after she angrily rebukes Motoyasu, Malty, and the King for freeing her slave status from Naofumi. This made Naofumi truly open to Raphtalia, becoming one of his greatest pillars of support.

Naofumi is constantly thinking of what would make Raphtalia happy. Though Naofumi considers himself a fatherly figure to Raphtalia, she has developed romantic feelings for him and is constantly trying to get him to notice her feelings. She is consistently let down by his personality, though she understands the reason that he acts the way he does and rarely steps in to stop him.

Raphtalia is the most important person to Naofumi and is considered his right hand, and is among the few people in Melromarc whom he completely trusts. It was because of Raphtalia that Naofumi seriously considered what his reasons were for fighting the Waves. She distresses over the idea that Naofumi would return to his world and leave her.

Motoyasu Kitamura
Motoyasu thought Naofumi was forcing Raphtalia to be his slave and took it upon himself to "free" her. He challenged and defeated Naofumi in a rigged Sacred Duel and forcefully removed her slave crest. He expected her to be grateful and give him a warm hug, but instead, his actions only upset her and she slapped him across the face for coming to his own conclusions and left with Naofumi. Though she doesn't hate Motoyasu quite as much as Filo does, she doesn't really care for him either.

Despite his stupidity, even Motoyasu was able to see Raphtalia's romantic feelings for Naofumi were genuine and asked him about their progress, only to be angered when Naofumi reveals his own denseness. Naofumi feels that Motoyasu's reason for freeing Raphtalia might be because of her being a cute girl and his desire to form a Harem which at that point didn't have any demi-human.

Ren Amaki
At their first meeting, Ren asked her not to hold him back, implying her to be inferior to him. But, most of the personals agreed that she was stronger than Ren many times. Éclair the sword master respected Raphtalia's prowess rather than his, causing him to become envious of her.

Itsuki Kawasumi
Itsuki was under the same impression as Motoyasu, that Raphtalia was being forced to work under Naofumi, which reinforced his bad opinion of Naofumi because he was from a time and place where slavery wasn't tolerated and thus branded as evil. However, after Naofumi's name was cleared, he asked Raphtalia about her relationship with Naofumi and her thought of wanting not to fight and be free, but her negative reply betrayed Itsuki's feelings and thoughts, which were seen in his face.

Filo
Filo is Raphtalia second traveling/fighting companion after Naofumi. When Filo first hatched and grew as a normal Filolial, Raphtalia initially only saw her as comrade to help her and Naofumi in their travels but was also somewhat jealous on how Naofumi became attached to her. This was first hinted when Naofumi starts showing emotions and expressions that she never seen until Filo joined.

When Filo takes on a human appearance, she began seeing Filo as a love rival for Naofumi's affection. As a result, Raphtalia gets jealous whenever Naofumi gives Filo special attention. They later develop a sisterly relationship where they both friendly compete for Naofumi's affection as they both share the common problem of him not seeing them as love interests. This bond is also shown on how well they work together in battle and display great concern for each other. When Raphtalia though that Filo was killed by a Dragon Zombie they were fighting, she was greatly disheartened and became relieved that Filo survived. Ralphtalia also shown concern whenever Filo picks up any of Naofumi's bad habits.

Melty Q Melromarc
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.

Keel
The two are childhood friends who lived in the same village before the Wave destroyed it. They also became slaves under an abusive master because of how they were demi-humans. They would go separate ways with Keel believing that Raphtalia died. When they reunite, Keel expressed great joy and worry for Raphtalia, initially believing that Naofumi was treating her badly. After Keel was rescued, she claimed how she too will become stronger so that she can protect Raphtalia too. When Keel becomes Naofumi's companion under a slave contract, she tries her best to be useful to her comrades, including Raphtalia.

Rishia
They quickly get along, after learning that they both are in similar situations in regards to their love lives. They promise to help each other reach their goals. Both of them become pupils when learning the Hengen Musou martial style.

Sadeena
Raphtalia sees Sadeena as a reliable person. When she was growing up, Sadeena acted as her family's guardian.

Atla
When Raphtalia recognizes Atla's affections towards Naofumi, the two became rivals in both love and combat where they would spar with each other. Like how Raphtalia is considered Naofumi's sword, Atla desires to be Naofumi's shield. For Naofumi's sake, they both are willing to work together.

Erhard
Raphtalia considers Erhard to be a very kind man and a bit of a mentor, as he was the first person to instruct her on the basics of proper sword usage. He was worried about her condition at first but amazed at her being in good shape with Naofumi.

Eclair Seaetto
Raphtalia was under the governorship of Eclair's father. They view each other in good light. Eclair taught her in depth about swordsmanship.

Mirellia Q Melromarc
It was her actions that led Raphtalia to Naofumi, though not directly. Mirellia wanted the slave trader to sell Naofumi a slave, and asked her Shadows to arrange for it; however, she didn't specify whom to arrange, and was surprised when a demi-human of Seaetto territory became the Shield Hero's party member. Raphtalia was grateful for Mirellia's action later.
