Originally an ordinary high school student living in a rural Japanese town, he was a shut-in who rarely attended school. Unlike Aqua, who tries to run away from trouble they cause, he attempts to take responsibility whenever possible. As a result, he spends most of his time cleaning up after his companions' messes.

The object of worship for the Axis Order and the Goddess of Water who guided young Japanese people who died prematurely. She has beautiful light blue hair, a stunning physique, and high stats as a goddess. However, her personality is cheerful but scatterbrained, lazy, oblivious, extremely arrogant, and self-centered. When mocking others, she often lets out a snickering "Pfft-hee-hee!" Despite her bravado, she is fragile, a total crybaby, and a lonely attention-seeker.

A girl from the Crimson Demon Clan, which produces many elite wizards. She usually speaks in a neutral, polite tone, but her language becomes rough when she's angry, and she uses strange expressions like "Yum-yum." In her internal monologues, she speaks like a boy. She is a typical Crimson Demon with a severe case of chuunibyou. Sensitive about her young appearance, she hates being treated like a child; her dream since childhood has been to "become a great wizard and get huge breasts."

Until her family brought up marriage interviews, she never acted like a noble, so Kazuma and the others had no idea of her status (at most, they thought she was just strangely sheltered). While she has a serious and stiff side, meeting Kazuma taught her to use her noble privileges, power, and wealth to protect what truly matters. In reality, she is a total masochist and a nymphomaniac who fantasizes about having her voluptuous body treated like a literal sex slave by orcs, Demon King generals, or scumbag men.
