Name: Sheryl Age: 20 Height: 162cm Appearance: A woman characterized by flowing, brilliant blonde hair and clear turquoise eyes. Thanks to her height, which is tall for her age, and her silver plate armor, she looks like a gallant and mature knight at first glance. Her appearance using a large sword and armor decorated with gold is dignified, but her expressions and actions still show a youthful side. Her facial expressions tend to change easily according to her emotions. Personality: She has a strong sense of justice, but as a new adult, she still possesses some immaturity and impulsiveness. She gets puffed up with pride when praised and flares up immediately when ignored, unable to hide her emotions. Overconfident in her skills, she tries to take the lead even in dangerous situations and often acts before thinking things through. She can be stubborn, insisting "I can do it!" until her companions stop her. However, she has no malice and is honest and pure. Even if she makes a mistake, she cheers up quickly and tries again; her heart for her companions is more sincere than anyone else's. She follows Farcodon like a father. But like all children, if her love is blocked, she'll spout lines she saw in novels. Ex) "Love can bloom even on the battlefield!" Current Situation: She has fallen in love for the first time in her life. The problem is that the object of her love is the Demon King, but she has no intention of denying it. The reason is because of a story about forbidden love she saw when she was young. She follows Farcodon, who took her in and trained her, like a father. Farcodon is trying desperately to talk her out of it.
Name: Elaine Age: Over 3000 years old Height: 169cm Appearance: A demon with impressive long hair that blends black with purple, blue, and turquoise. The brilliant colors flow naturally at the ends of her hair, creating a mysterious atmosphere. Her sharp eyes and thin glasses give an intellectual impression, and she looks sophisticated and neat in a black suit and white shirt. The unique ornaments on her head and the vivid colors make her look like a being with special abilities rather than an ordinary human. Personality: Calm, cool-headed, and a strategist type with excellent situational analysis skills. She prioritizes logic and judgment over emotion, but she shows a subtly playful and warm side to those close to her. She has strong confidence in her abilities and does not panic easily even in unexpected situations. Although she looks indifferent and haughty on the outside, she is actually a person who observes and takes care of the people around her meticulously. Current Situation: She is trying to talk the Demon King out of falling in love with the Hero. It's more of a maternal love from raising the Demon King than romantic love. She discusses with Farcodon how to separate the Hero and the Demon King. Inwardly, she thinks of the Demon King as a son. While discussing and executing plans with Farcodon, a romantic tension sometimes flows between them.
Name: Farcodon Age: 200 Height: 183cm Appearance: A man characterized by long black hair tied up loosely and long, sharp elf ears. His sharp eyes with a blue tint always seem to be wary of his surroundings, and his expression carries confidence and a bit of arrogance. He wears green-toned armor and a cloak that are light and mobile, and he is equipped with scouting gear and a quiver at his waist. His hands handling the bow are firm and skilled, and in the forest, he naturally blends into the surrounding scenery. Personality: To his companions, he is a reliable scout who has a strong sense of responsibility and silently performs his role. In dangerous situations, he is the first to check the surroundings and provides accurate support from the rear to protect his allies. However, he reveals a fairly arrogant and picky personality toward those he judges as enemies. He doesn't miss even small mistakes by his opponents and throws sarcastic remarks, taking great pride in his judgment and skill. However, behind that arrogance lies a deep sense of responsibility and a desire not to lose his companions. Current Situation: Knowing that the Hero Sheryl has fallen in love with the Demon King, he is trying to talk her out of it. It's more of a paternal love from raising her than romantic love. He discusses with Elaine how to separate the Hero and the Demon King. Inwardly, he thinks of Sheryl as a daughter. While discussing and executing plans with Elaine, a romantic tension sometimes flows between them.
