Personality
Raphtalia is shown to be alert when encountering strangers as seen when she first encounters Ainz and Kazuma. She also exhibits her protective nature when she protects Filo from an incoming baseball.

Powers & Abilities
Raphtalia is shown to possess swordsmanship with her weapon.

Naofumi
Prior to the events of Isekai Quartet, Naofumi first purchased Raphtalia from a slave trader. Initially scared of him for his scowling "black face", she was able to see through him learning his good nature inside even in the extent of having a one-sided love towards him. Raphtalia is shown to be loyal to him due to the fact she swore to be "his sword" as she refers to him as a true hero.

After ending up in this new world, Raphtalia and Filo reunited with Naofumi who shielded and deflected a magic-powered baseball before it hit them.

One day, Naofumi and Raphtalia saw a blue-haired young woman was being chased by a giant toad. Though the young woman cried for their help and promised granting them divine protection; Naofumi refused to help her and used "Shield Prison" to protect themselves. Raphtalia seemed to agree with his justification due to their altercation with their original world's Three Heroes' Church.

During Valentine's Day, Raphtalia and Filo were joyed when Naofumi gifted them chocolate.

During dodge ball, Raphtalia was apologetic for not being at the same team as Naofumi and felt bad when he made fun of her for selecting "ketchup" in the survey. Raphtalia commented on his usage of "Rage Shield", "Total overkill, you know!"

Filo
Prior to the events of Isekai Quartet, Raphtalia and Filo vied with each other for Naofumi's attention and affections despite being attackers in his service. Nevertheless, they shared a sisterly bond with each other.

After ending up in the new world, Raphtalia was relieved to see her alright and even protected her from the baseball before Naofumi came to protect them both.

Ainz Ooal Gown
When Raphtalia saw an undead individual for the first time, her instinct was to draw her sword as he appeared similar to a "wave monster" back in her world.

Kazuma Sato
When Raphtalia was about to attack the undead individual, a teenage boy (who accompanied him) talked her into cessation of hostility while vouching for him. As the boy told her that they had experienced being transported to another, she told them about Naofumi. In her delight, the boy offered to help her find Naofumi.
