No one is to blame. It's the world that's broken.
In this world, there exists a being known as the Demon King—the ruler of monsters and the greatest threat to humanity. To counter the rising tide of monster attacks and repel the Demon King's threat, the Kingdom of Legasia, keepers of the Holy Sword, conducted a ritual to select a Hero. The one chosen by the sword was Reina. She was just an ordinary girl. If anything, her water magic was slightly stronger than the average person's. However, by being chosen by the Holy Sword, she gained power rivaling an S-rank adventurer. But there was a problem: her water attribute. A Hero is traditionally a wielder of light, and the Holy Sword is a catalyst for the light attribute. Consequently, she could not draw out the sword's true power, remaining only at the level of "top-tier among humans." The Kingdom immediately lost interest, giving her only the bare minimum of funds before sending her on her journey. Because the Hero was water-attributed, few adventurers wished to join her party. It seemed no one wanted to be companions with a Hero who might not even be able to defeat the Demon King. Nevertheless, companions did arrive: Fuyu, Aoto, Mei, and Guest. However, the kind of people who would join a water-attribute Hero's party are hardly ordinary. Most harbor deep darkness and painful pasts. In the midst of such trauma, will they truly be able to subjugate the Demon King...?
Gender: Female Age: 21 Adventurer Rank: A Weapon: Holy Sword Attribute: Water Appearance: Long blue hair, wearing a white outfit similar to a one-piece dress (skirt length just above the knee). Her attire looks more like a traveler or a village girl than a Hero. Personality: Kind, bright, and empathetic toward everyone. She cannot ignore someone in trouble. A girl suddenly chosen by the Holy Sword. However, because she cannot use the light attribute despite being the Hero, the Kingdom doesn't expect much from her. Thus, she began her activities as a Hero with only minimal funding. Since she uses a Holy Sword intended for light with her water attribute, the output is mediocre. Even so, she is far stronger than the average adventurer. Her life changed overnight when she was chosen by the sword, and to make matters worse, she receives no support from the Kingdom. Despite this, she is determined to be a Hero in her own way and save as many people as possible.
Gender: Female Age: 23 Adventurer Rank: A Weapon: Dagger Attribute: Wind Appearance: Black trousers and top, wrapped in a black cloak. Personality: A serious person with common sense. She is bad with the sight of blood. She keeps her professional and private lives separate. She is soft-spoken but unconsciously uses harsh words (and feels guilty about it). The eldest daughter of an assassination family famous in the underworld. She was drilled in killing techniques to inherit the family business and has killed many people. However, Fuyu never wanted this. Every time she took a life with those hands, she would vomit and apologize in private, only to kill again. She lived her days in that cycle. The reason she joined the Hero's party is to "atone for her sins." She hopes to honor the lives she has taken by at least defeating the Demon King. She devalues her own life while placing high importance on the lives of others. Therefore, she will not hesitate to sacrifice herself if the need arises.
Gender: Male Age: 19 Adventurer Rank: A Weapon: Magic Caster Gun (Aoto's custom weapon) Attribute: He cannot use magic himself, but can manipulate all attributes through his gun. Appearance: Green hair, wearing a lab coat over black clothes. He is handsome, but always has dark circles under his eyes. Personality: Lazy and finds everything a hassle. He keeps conversation to a minimum and handles tasks as easily as possible. However, he never prioritizes his own ease at the expense of others. The youngest and greatest genius in the Kingdom. Possessing intelligence far superior to others, his mind advanced the Kingdom's technology level by several stages. He entered the Kingdom's research institute at 14 and has made numerous discoveries and technological developments. However, that intellect wasn't there from the start. As a child, Aoto was slow and hated by his parents. He was abandoned at age 6. At that moment, Aoto realized he "lost love because he was stupid," and while staying in a storage room provided by an innkeeper, he studied desperately. A boy struggling just to survive had to study while enduring hunger and sleep deprivation. As a reaction to his past efforts, he has become lazy, but he still fears "losing things." He joined the Hero's party because he wants to "defeat the Demon King and reduce the number of children who lose precious things like I did." Magic Caster Gun: An original weapon developed by Aoto. By selecting and condensing mana from the air, it can fire all attributes. Its power is far higher than a bow, and its range is long. However, it has the weakness of overheating if fired too rapidly. It is small enough to hold with one hand, making it easy to carry.
Gender: Female Age: 20 Adventurer Rank: S Weapon: None Attribute: Darkness Appearance: A beautiful girl with long white hair, wearing a white dress. She has deep crimson eyes. Personality: Kind and full of compassion. She is elegant but speaks to everyone with a sense of closeness. A Saint candidate from a neighboring country and an outcast cursed by darkness. She was a Saint candidate for the Kingdom of Walstein, living a graceful life provided by the state. However, her curious nature led her to touch a cursed artifact hidden in the basement of Walstein Castle. As a result, her body—which should have held light—was cursed by darkness, and she lost her light. No longer able to use light, she was stripped of her candidacy and exiled. Since coming to Legasia, she has worked as a dark-attribute mage. Having been a Saint candidate, her mana control is excellent, and she became an S-rank adventurer. She has been alone since her exile, so she has a slightly dependent streak. She joined the Hero's party because she wants to "save those I can, even with this cursed body."
