Hestia is a beautiful and petite Goddess with a youthful appearance. She has blue eyes and mid-thigh length black hair tied into twin-tails which reach down to her mid-thighs. Her hair is tied with hair accessories that feature blue and white petals along with bell-shaped ornaments, which were gifted to her by Bell. She has a small frame (4' 7"), which further emphasizes her breasts, hence the nickname "Loli Big-Boobs." Her usual attire is a white mini dress with a blue ribbon around her neck and one tied under her breasts around her arms, and a pair of white gloves. She is usually barefoot, but occasionally wears a pair of white flip-flops. Hestia is a kind and energetic Goddess. She is always full of energy and is very passionate about her feelings. This in turn makes her someone with a surprising determination, willing to spend three whole days in dogeza position to get a weapon for Bell until Hephaestus finally relented. On various occasions it has been pointed out that she is kind to others. She does not discriminate against anyone and is fair with everyone, even Hera. Both Hephaestus and Penia have noted that she was the only one who didn't make fun of their flaws, the deformity in her friend's eye and the latter's status as a Goddess of Poverty. Hestia is well known for it, which caused Loki to be shocked when she referred to Dionysus as terrifying. On the other hand, she is compassionate and understanding, shown when she accepted Wiene and let her stay in her home even though she was a monster after seeing she was just like a kid. Although they have a serious mutual enmity, Loki has recognized her kindness as one of her greatest qualities. She is a pacifist, so she usually avoids conflict if possible. In Heaven, she came to give Dionysus her place among the 12 main Gods of Olympus to prevent a conflict between him and the other Gods. Freya noted that she possesses a strong sense of justice, commenting that she would be upset if she saw a slave market. While she is a quite simple Goddess, and is often teased by many other Gods for being childish, her demeanor has caused her to have relationships with a wide variety of them and her status as Goddess of the immortal flame makes her someone with authority and an undeniable high position, with Loki suspecting that even Ouranos and Zeus acknowledge her. Despite all her good features and her typically nice demeanor, Hestia is very different when it comes to Bell. Having fallen in love with her first dependent, she dreams of having a relationship with him and is extremely jealous. Every time she finds out about a new relationship of Bell with a girl, she becomes exalted and seeks to see if that woman has romantic feelings for him. In cases where she confirms her fears, she acquires a hostile attitude regarding Bell, seeing all of them as her love rivals. She often argues with Lili about the boy, which is the greatest example of this. She has a notorious antipathy towards Ais due to Bell's feelings for her. Likewise, she constantly tries to keep them apart and maintains her sullen attitude towards her even when Bell is not present. Her dislike and jealousy for her even served as her main motivation to hide from Bell the existence of his skill Liaris Freese, even surpassing her desire to protect him. Her jealousy usually makes her act irrational. She once completely prohibited any form of physical contact between men and women of her Familia after seeing Bell and Haruhime holding hands. Despite being a virgin goddess, she can be naughty and perverted as she once entered the bathroom to see Bell naked while he was bathing. While her insanely possessive demeanor stands out most of the time she spends with Bell, Hestia has occasionally acted appropriately and shown healthy concern for him as well. She has comforted, supported and motivated the young adventurer in times when he was discouraged or did not know what to do, in addition to defending him after he earned the hatred of all Orario. Although she proves to have a preference for Bell, she is a Goddess who has a deep love for her entire Familia. She always supports them in the decisions they make and tries to encourage them if they are down. Despite her feelings for Bell, she told him to go for Lili back when they fought after the Pallum found out about his feelings for Ais. Likewise, she was fully willing to take responsibility for their actions regardless of the severity and help them through their entire odyssey to save the Xenos. She has been shown to be oblivious at times, as she did not understand Loki's warning regarding Freya at the Denatus or when she caused a stove to blow a Jagamarukun stand sky high. Hestia possesses a certain sense of responsibility, refusing to accept the help of her Familia members to pay her debt for the Hestia Knife, arguing that it was hers and declaring that she would pay it no matter how long it took. In turn, this also proved that she is a hard worker, as she holds two jobs just to pay off the debt. However, she still has a lazy side that she can get carried away by if allowed to, as she stayed with Hephaestus until she was forced out and later took a while to find work.
