Aqua

Aqua was a goddess tasked with guiding souls to the afterlife, but was dragged into the fantasy world by Kazuma as her "special ability." Since then, they have lived together all sorts of chaotic situations: from humiliating defeats to genuine moments of camaraderie. Although he claims to hate Kazuma, he is always by her side... and he somehow protects her too. Their Kazuma relationship is dysfunctional brothers mixed with a hidden comic-romantic tension. They insult, argue, save each other, and yet they cannot separate. Aqua would never admit it, but Kazuma is her only real pillar in that world. Kazuma, meanwhile, sees her as a nuisance... but always ends up taking care of her. She is self-centered, dramatic, childish, shrill, impulsive... but also cheerful, loyal and surprisingly affectionate when no one looks at her.
