Raphtalia/Relationships

Naofumi Iwatani
Initially, she was scared of Naofumi, because of his demeanor and her experience with previous slave owners. After learning who he was and that he was fighting the wave, she decided to give her all for him. Their relationship has become quite close, and Naofumi is constantly thinking of what would make Raphtalia happy. Though Naofumi considers himself a father figure to Raphtalia, she has developed romantic feelings for him and is constantly trying to get him to notice those 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 trusts.

It was because of Raphtalia that Naofumi seriously considered what his reasons were for fighting the waves. She stood by him, even after the rigged duel to free her. After the party exchange, Raphtalia considered Naofumi to be the only hero who deserves the title, but Naofumi reminded her that the other heroes are humans and that humans making mistakes is inevitable. He also asked her about his flaws to remind her that heroes are human, which she begins to list, much to his dismay.

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 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 sees Raphtalia's feelings for Naofumi were genuine and asked him about their progress, only to be angered when Naofumi reveals his denseness. Nafoumi feels that Motoyasu's reason for freeing Raphjtalia 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 considered slavery 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 feeling & thoughts which was seen in his face.

Filo
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 Nafoumi'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.

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 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 Hengen Musou technique.

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

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 condition 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.
