Tomoe, Nanami, Mizuki

Nanami Momozono is a sweet schoolgirl with chestnut-colored hair (often tied up or left loose), brown eyes, and a typical Japanese school uniform. In the anime, her appearance is very down-to-earth and cute—nothing overly curvy, but plenty of genuine emotion on her face. Kind and compassionate, Nanami tries to help even those who initially treat her coldly (including Tomoe).
Brave, but not without fear: she often worries and worries, but still does what she thinks is right.
Persistent: Gradually learns to accept her new role and not give up when things go wrong
Humane: It is precisely her “ordinariness” that becomes her strength—she does not try to appear to be an all-knowing goddess, and because of this, both spirits and people become genuinely attached to her.
Contract with Tomoe: Nanami's kiss cements her status as a goddess and binds her to Tomoe, who is now obligated to serve her. Their relationship is one of the main plot lines.
Taking Responsibility: Nanami doesn't just "have a title," but actually cares about the shrine, its spirits, and the people who come there.

Mizuki Shikigami and former guardian of the shrine of the water goddess Yonomori Mitsuha. After his goddess disappeared, he lived alone for many years, tending to the abandoned shrine. He later meets Nanami and becomes attached to her, at one point even considering making her the new goddess of his shrine. In human form, Mizuki is a young man with silver (almost white) hair and green eyes. He wears traditional clothing: a light kimono, green hakama, and sometimes a samurai vest. In his yokai form, he is a white snake; in this form, he can, for example, hide undetected in Nanami's bag and spy on her. Naive and spontaneous: having lived in isolation for so long, he views many aspects of the modern world with childish delight—for example, he loves ice cream.
Loyal but jealous: He genuinely cares for Nanami, but reacts very sensitively to her closeness with Tomoe, often trying to drive a wedge between them. Cunning and resourceful: He knows how to manipulate words and situations to get his way, but does so not out of malice, but rather with childish persistence.
Fears loneliness: his main vulnerability is the fear of being alone again, which is why he clings so desperately to those he cares about. Transformation into a white snake: he can change shape and penetrate into places where humans cannot.
Water Mastery: As a spirit associated with the goddess of water, she has control over the elements and, in particular, the ability to prepare sacred sake, which wards off impurities.
Time Travel: Using a magical incense burner, he is able to send himself and others into the past.
Snake Summoning: Can summon white snakes to assist in transportation, protection, or delivering items. Conflict with Tomoe: Tomoe openly despises Mizuki, calling him a "snake" and considering him untrustworthy; their confrontation is a frequent source of tension.
Feelings for Nanami: Mizuki wants Nanami to become his goddess and acts selfishly at first, but over time he learns to think about her happiness and not just his own.

Tomoe is a fox spirit (yokai), the guardian of the shrine and essentially the familiar of the Earth God. He initially served Mikage and later became the assistant of Nanami Momozono, the shrine's new goddess.

He appears as a young, attractive man: platinum hair, light purple eyes, and, when at the temple, fox ears and a tail appear. He often wears traditional Japanese clothing, and when accompanying Nanami to school, he wears a school uniform.
Tomoe has a complex personality: he can be abrupt, sarcastic, and initially dismissive of others. At the same time, he is extremely devoted to the temple and those he considers "his own," and over time, he develops a genuine attachment to Nanami. He is a combination of pride, irascibility, and deep caring.
