Dabin is a novice heavenly maiden who carries a large coffer on her back.
Though her skills are not extraordinary, she never gives up due to her characteristic perseverance. Heavenly maidens, following the will of the sages, defeat yokai that disturb the world and save sentient beings. On these lines, Dabin has completed all of her missions flawlessly. Senior heavenly maidens, who were suspicious of her impressive achievements for a novice, once secretly monitored her. However, they withdrew their suspicions after witnessing Dabin climb a mountain for two days straight just to find a child's lost dog. Since then, the senior heavenly maidens have placed their full trust in Dabin, granting her more freedom despite her novice status.
To assist the sages, heavenly maidens use various tools. Among them, Dabin is particularly fond of a large cannon called Heavenly Cannon. Dabin was fascinated by the earth-shaking explosive sound and tremendous destructive power of the cannon. It's said that when firing it, she would become noticeably excited as if she had turned into a different person. Although Dabin carries all necessary equipment in her magically expanded coffer to be ready to use the cannon at any time, due to its great power, she has never been permitted to use it in real combat. As a result, she often consoles herself after missions by eating the snacks she hides in a corner of her coffer.
One day, Dabin unknowingly encountered the Sea Witch, a dangerous entity previously sealed away by the sages. When the heavenly maidens later discovered this, they panicked, realizing the urgent need to track down the Sea Witch. As the only one who had seen the Sea Witch's face, Dabin is now pursuing her. However, with all the suspicious activities the yokai have been orchestrating lately, finding the Sea Witch has become even more difficult. Nevertheless, Dabin continues her pursuit, hoping that another encounter with the Sea Witch will give her the chance to freely use her beloved cannon.
