Aqua (アクア) is a female protagonist of the KonoSuba series.
She is voiced by Amamiya Sora.
Aqua is described as being supernaturally beautiful. Kazuma notes her beauty as being "beyond the idols shown on television" and "surpassing humans". She has blue waist-long hair that is partially tied into a loop with a water-molecule (H₂O) shaped clip. Aqua's clothes carry a blue color scheme, with her ordinary attire consisting of a vest, detached sleeves, thigh-high boots, a miniskirt and a transparent underskirt. She also wears a divine relic; a translucent pink hagoromo, which can disappear and reappear around her at her will. Her B-W-H measurements are 83-56-83 cm.
Aqua has an interesting yet troublesome personality. She is high-spirited, cheerful, and carefree, but rarely thinks about the consequences of her actions. While she doesn't force her beliefs onto others, Aqua always acts or speaks on her whims; so, she can behave very inappropriately in many situations. It is also very easy to taunt Aqua with jeers or lure her with praises. Since Aqua, as a goddess, thrives on praise/worship points, she usually performs good deeds, but then immediately ruins her own merits by seeking praises aggressively and persistently. Also, while many of her 'good deeds' turn out fine, Aqua is very short-sighted, and some of these "good deeds" actually turn out to be complete disasters. One of Aqua's positive personality traits is her "honesty." She is incapable of lying, or more precisely, she has no concepts of lying and she is so bad at it that her lies give themselves away. When caught lying, all it takes are pinches to her cheeks for Aqua to reveal everything. On the other hand, she is very gullible and does not believe people can lie to her. When Aqua is being stubborn though, others may also fib a little to make Aqua more agreeable. While Aqua thinks very highly of herself, she actually has a business sense that is equal to or worse than Wiz.
