Although she looks dignified at first, Aqua is the opposite of what is expected of a goddess, being sloppy, disrespectful, and touchy, often mistreating and mocking Kazuma. Also, while she often calls Kazuma a "hikkiNEET", Aqua herself is a loafer too, as, although she is more lively and fun-loving than Kazuma, Aqua also spends most of her time doing nothing or getting wasted, and is easily influenced by both Kazuma and Cecily's bad behaviors.

Also, due to her low Intellect, Aqua is absent-minded, heedless, forgetful and unable to understand complex conversations or situations. Her low intelligence, combined to her poor Luck, are the reasons why most of her ideas and actions end up in a "critical failure". Aqua is, however, very intuitive and astute, guessing correctly what her party's antics, as well as thinking fast in the rare occasion she is focused.

Furthermore, Aqua is a crybaby. Since she is oversensitive and prone to fear, Aqua always cries when she is scared, upset, or traumatized. Also, like a child, Aqua fakes crying sometimes to get what she wants as well as throws a tantrum. In addition, like a kid, Aqua is wasteful, often spending all her money partying and getting drunk with no thoughts for tomorrow. Being a bohemian is even one of the doctrines of her cult.
