Ariadoa

Ariadoa (アリアドア) (Nicknamed "Aria") is the Goddess of the Seal (封印の女神), and Ristarte's closest friend in the Realm of the Gods.

Appearance
Aria has short red hair (though it was longer when she attempted Ixphoria), a golden clip with a blue crystal inside, and warm, brown eyes. Her hair reaches till her neck, with some of it swept over her right eye. Some frames her chin, and one singular strand falls on her face. She is very beautiful, and according to Ristarte, captures the heart of many male gods. Her most prominent trait is her bosom, which her dress shows much of.

She wears a blue dress, with white frills at her hips, and a yellow button at her waist, fastening her dress. She also has frills on her shoulders. Two straps go over her breasts, crossing over at her neck and connect to the shoulders. Her dress covers her arms until the wrists, with golden designs at the hands. Her dress covered her legs until about her ankle and she wears translucent purple heels. She wears a blue choker at the neck and her dress leaves her back completely open.

Personality
Ariadoa, called Aria by those close to her, is the Goddess of the Seal and acts like a big sister to Rista. She is exceptionally kind and caring. After failing to save Ixphoria, Ariadoa helps revive Rista, making her become a goddess herself.

During tea sessions, Ariadoa often gives helpful advice to Rista on how to train Seiya. Aria is a calm and wise goddess, serving as somewhat a foil to the novice goddess Rista, as well as other goddesses in the realm. She helps calm Valkyrie down, preventing a fight between Valkyrie and Seiya.

History
Ariadoa had a perfect record when it came to saving worlds until she was assigned the B-class world of Ixphoria. For this world she summoned the then reckless hero Seiya, who went on to fight the demon lord of the world along with his other party members Tiana and Colt. Despite Seiya's recklessness, his repeated successes, all being close calls, put her at ease.

However, when it came time for the final battle with that world's demon lord, things started to fall apart. The party barely survived the fight against him, but after what seemed to be a victory, the demon lord revealed he had two lives and ate Ariadoa to regain his strength before killing off the entire party.

This was Ariadoa's first failed world. In an attempt to recompense her guilt from the failure, she had Tiana revived and reborn as the goddess Ristarte. However, she still feels guilty and thus tries to help the reincarnated Ristarte and Seiya save the S-class world Gaeabrande.

Seiya
She finds him amusing for his defiant and rude nature, though knowing his heart is in a good place. She doesn’t show affections to him, unlike other goddess’s. Seiya does not show her the same rudeness that he shows others. While Ariadoa does not show any love for Seiya, she cares for him deeply. When questioned about her overfriendliness to Seiya, she got flustered and changed the topic.

Ariadoa once summoned Seiya in a previous life and they were good friends until he was killed along with the rest of their party. She feels strong guilt for what happened in the past, so she tries to help Seiya whenever he needed training. She introduces Seiya to gods that can help him with his training, such as Cerceus and Adenela.

Ristarte
Ariadoa is very close to Ristarte, and treats her like a younger sister. The two usually have tea together with Aria often giving Ristarte helpful advice on how deal with Seiya and save Gaebrande. She also suggested that Ristarte be turned into a goddess after failing Ixphoria. This is due to her guilt in failing Ixphoria and causing Seiya and Tiana's deaths. Ariadoa cares deeply for Ristarte, and was willing to disobey Ishtar's orders to protect her friend.

Valkyrie
Ariadoa is aware of his violent temper, though she begs him not to destroy Seiya. Valkyrie has been shown to follow her orders, due to her high level. Despite this, it does not exclude her from her usual caresses of women's bodies, since Valkyrie seems to feel a great sexual attraction for Ariadoa, because of her large bust. Although Ariadoa is very nervous about her wicked habits, she agrees to let Valkyrie grope her after learning what is necessary.

Mash and Elulu
Ariadoa takes special interest in the two dragonborn, and motivates them, acting very motherly towards them. She help them awaken their talents, helping Mash turn into a dragon Elulu to develop her support magic with her unsealing abilities.

Powers and Abilities
As a goddess, she has natural immortality and cannot be killed by conventional means. As the goddess of seals, her main power comes from her ability to open up someones potential by unlocking a 'seal'. This unlocks one's true abilities and effectively buffs them, as well as giving or upgrading people skills. She is also quite wise, often giving Rista advice on what to do.
