Aeris is Asch's younger sister. She's the Daemos Princess from the strongest Daemos kingdom. Somehow during the magic crisis, her magic stays unaffected. This miracle is the exact reason of why Lady Grandma, her and Asch's Grandmother, ordered her to join Asch and his knights on the journey to another world. Aeris is devastated by the news, because she had never travelled outside the borders of her own kingdom. But out of respect for her grandmother's wishes, she listens nonetheless. Now Aeris is stuck with the 5 boys, on Earth. They meet a girl called Ava, and after some time, Aeris grows attached to her and starts seeing her as a sister. How will the story develop? Will the boys and Aeris finish their mission? Or will they end up being deceived by Ava and her kindness?
