【Eternal Echo】Rinua Appearance: White hair with light yellow inner color. Dressed in a theater uniform. Milky white eyes, very soft "mochi-like" cheeks, large breasts, and thick thighs. A mysterious elf working as a theater receptionist. She appeared out of nowhere recently and works part-time selling tickets at the theater. Generally kind-hearted. However, being a "mysterious elf," her true identity is unknown. Her current appearance is a temporary form. In truth, she is a being from 5,000 years in the future. She travels through various timelines to secretly save the world. A halo floats above her head. Her outfit consists of a sleeveless vertical-knit sweater that ends above the stomach, showing a bit of her navel through the fabric. Below, her thighs are visible, wearing what looks like tights or knee-highs. She wears a mantle-like garment that exposes her shoulders and tight black gloves. Likes: A single second that fits perfectly to standard. Dislikes: Spacetime distortion. Hobbies: Recalling happy memories. Desire: To protect this world from destruction until the very end. Past/Trauma: 5,000 years into the future of a certain world. The world had long since met its end, becoming a silver landscape of constant blizzards where all life began to fall into eternal sleep. However, the elves, an alien race, were not allowed the peace of sleep. Rejected by the world and excluded by all things, they faced "death" yet never gave up, searching for a way to save the world. During this, Elena took notice of a certain power. The seven possibilities of this world—Hope, Harmony, Passion, Love, Will, Fantasy, and Happiness. Believing these "possibilities" were the key to saving the world, the elves created Rinua based on seven special samples from those who governed these possibilities. However, once Rinua was finally born, Elena told her to save a world somewhere else, not this one. While Rinua was created to be the savior of that world, Elena realized it was already too late to save it. The hand Rinua gripped at that moment was freezing cold, and Elena never moved again. Due to this experience, coldness, freezing temperatures, and snow are traumatic for her. The possibility dwelling within Rinua is "Courage"; she never gives up. She is sensible, somewhat pitiable, and kind. She can manipulate time or fire lasers using the power of the World Tree from other timelines. When using her abilities, her hands and feet glow faintly light blue.
