Ristarte appears as a beautiful young woman with long blonde hair, typically styled with a blue ribbon tied near the top. Her striking looks often leave a strong impression on mortals, many of whom consider her extremely attractive at first glance. As a goddess, she wears a flowing white dress that reveals her shoulders, accentuates her chest, and exposes her legs, giving her a graceful yet slightly provocative appearance in line with the stylized aesthetics of divine beings in the series.

In her past life as the human Princess Tiana, Ristarte retained the same facial features and figure. However, her overall look differed, she had short dark brown hair and wore a pink bow in place of the blue ribbon, giving her a more modest and grounded appearance befitting her former mortal status.

As a novice goddess, Ristarte initially lacks the confidence and composure demonstrated by her more experienced divine peers. Her inexperience often results in clumsiness, impulsive decisions, and a stark contrast to the methodical nature of Seiya Ryuuguuin, the hero she summons. Despite her shortcomings, Ristarte is portrayed as a deeply compassionate and well-meaning individual who genuinely strives to fulfill her duties and protect the world she’s assigned to save.

Ristarte tends to favor Japanese men as hero candidates, believing them to be statistically superior and narratively suited for the role. This belief leads her to summon Seiya Ryuuguuin to save the S-ranked world of Gaeabrande drawn not only by his exceptional stats, but also by his handsome appearance. However, Seiya’s overwhelming power and obsessive caution shatter many of her preconceived notions about typical isekai heroes, challenging her expectations at every turn.

Ristarte is notably vain, often admiring her own beauty and becoming visibly offended when others insult her particularly if she’s called “stinky,” a recurring gag in the series. Despite this self-centered streak, she genuinely cares about the citizens of Gaeabrande, frequently healing the injured and ensuring Seiya is well-provided for, even when he acts cold or ungrateful.

Among the gods, Ristarte is viewed as a younger sister figure, often teased or underestimated by higher-ranking deities. Nevertheless, she gradually matures through the challenges she faces alongside Seiya, developing both spiritually and emotionally.

Ristarte also displays a romantic and occasionally lustful side, often fantasizing about Seiya and imagining herself as his wife. Though her feelings are played for comedic effect, they are hinted to stem from deep-rooted emotional ties, as Ristarte is later revealed to be the reincarnation of Princess Tiana, Seiya’s lost love from his previous life. This connection suggests that her affection for him may be influenced by residual emotions from her past existence.

Before becoming a goddess, Ristarte was once a human named Tiana, the princess of the kingdom of Termine in the world of Ixphoria. A skilled healer, she joined a party of heroes tasked with defeating the Demon Lord, forming a close bond with the group’s leader, Seiya Ryuuguuin. Despite Seiya’s reckless nature during this time, Tiana trusted him deeply and found comfort in his signature phrase, “Everything’s gonna be okay.”

Tragically, during their final confrontation with the Demon Lord, it was revealed that Tiana was pregnant with Seiya’s child. In a brutal twist of fate, both she and the unborn baby were killed before Seiya himself was slain. The trauma of this event left a deep mark on Seiya’s soul, while the guilt-stricken goddess Ariadoa arranged for Tiana’s reincarnation as the goddess Ristarte, approximately 100 years before the events of the main story.

As a goddess-in-training, Ristarte began overseeing the salvation of lower-ranked worlds destined for destruction. Eventually, she was assigned the daunting task of saving the S-ranked world of Gaeabrande. Without realizing his underlying trauma or personality shift, she once again summoned Seiya Ryuuguuin as her chosen hero, unaware that he was the same soul from Ixphoria, now reborn and extremely cautious due to his past failure.

Throughout their journey in Gaeabrande, Ristarte struggles to manage Seiya’s obsessive preparation and mistrustful attitude, often becoming frustrated by his cold demeanor. Despite this, she remains supportive and deeply involved in his efforts to defeat the Demon Lord.

During the climactic battle in Gaeabrande, Seiya uses the forbidden spell Valhalla Gate twice sacrificing himself to ensure victory. To save him, Ristarte overextends her divine Order powers, reviving him from death twice. This reckless use of forbidden divine magic results in her being punished by the gods, stripped of her powers, and reassigned to an even more dangerous mission: saving an SS-ranked world, this time without the aid of her goddess abilities.

As a goddess, Ristarte is immortal and cannot be harmed or killed by conventional means. However, in terms of raw power, she is considered relatively weak compared to higher-ranking deities. While her role as the Goddess of Healing implies supportive potential, her healing magic is often outclassed by common consumable items. Nonetheless, when pushed to her limits, she is capable of performing high-level restoration—such as when she fully healed Seiya Ryuuguuin after he suffered the life-threatening consequences of using Valhalla Gate.

Ristarte is capable of flight, utilizing a pair of glowing angelic wings. She possesses Flight (Level 14), allowing her to travel at speeds of approximately 60 to 80 kilometers per hour. While this grants her decent aerial mobility, Seiya is notably faster and more efficient in flight. Ristarte’s flight ability is strong enough to carry both Mash and Elulu, indicating a respectable level of physical strength for a support-type goddess.

She can also open dimensional portals between the Divine Realm and the world of Gaeabrande, allowing her and her companions to travel freely between realms as needed.

Interestingly, her loose strands of hair have been used by Seiya to synthesize powerful magical equipment, suggesting that her divine essence is potent even in small traces.

Ristarte also possesses the ability to scan the stats of others, similar to Seiya and Chaos Machina. If an opponent has masked their true stats using the Fake Out skill, she can tap into her “Megamic Power” to override the illusion and reveal their real abilities.

Additional abilities include:

While Ristarte’s powers may not rival those of combat-focused deities, her support skills, divine insight, and emotional resilience make her a valuable companion in any battle for world salvation.

Seiya Ryuuguuin
Ristarte shares a deeply intertwined fate with Seiya Ryuuguuin, having been his fiancée in a past life when she was the human Princess Tiana in the world of Ixphoria. During that time, Seiya was carefree and lighthearted, and the two were expecting a child together. However, their happiness was tragically cut short when the Demon Lord of Ixphoria killed them both, along with their unborn child. Though neither retained full memories of this life initially, the trauma left a lasting impression on Seiya’s soul, becoming the root of his overly cautious nature.

Upon summoning him in her role as a goddess, Ristarte is immediately attracted to Seiya’s appearance and remarkable stats, though his cold, dismissive behavior quickly frustrates her. Seiya frequently mocks her role as a goddess and shows little regard for her emotional well-being. He even uses strands of her hair, often plucked without permission, to craft weapons via his Synthesis skill. Despite his harsh attitude, Seiya displays moments of profound compassion such as preventing Elulu from sacrificing herself sparking hope in Ristarte and reinforcing her belief that she chose the right hero.

Their relationship begins to shift following Seiya’s death and resurrection. In their second mission together now tasked with saving Ixphoria once again Seiya becomes noticeably more gentle and emotionally receptive toward Ristarte. He acknowledges his feelings for her and allows small gestures of affection, such as holding hands or embracing. Though still plagued by caution and strictness, his concern is now clearly motivated by his desire to keep Ristarte safe, especially given the echoes of their past tragedy.

Ariadoa
Ariadoa, also known as Aria, is Ristarte’s closest friend and confidante among the gods. The two frequently spend time together, often sharing tea or discussing divine assignments. Ristarte deeply admires Aria, valuing her guidance and her ability to connect Ristarte with powerful gods and goddesses who can aid in Seiya’s training. Their bond dates back to Ristarte’s mortal life, and it was Aria’s guilt over the failure in Ixphoria that led her to request Ristarte’s reincarnation as a goddess.

Despite their close friendship, Ristarte harbors jealousy toward Aria, particularly over her near flawless track record in saving worlds and even her larger bust size, which Ristarte considers unfair competition. Nonetheless, their bond is unshakable. Aria remains one of the few individuals who can reach Ristarte during moments of despair, particularly after Seiya’s death.

Mash
Ristarte maintains a friendly and supportive relationship with Mash, one of Seiya’s dragonkin companions. She recognizes his strength and potential, trusting him to help defend Gaeabrande and protect others. While generally patient with him, Ristarte occasionally becomes exasperated when Mash begins to mimic Seiya’s absurd levels of caution, an influence that frequently causes her stress.
