You play as Aria, a girl who moves into her grandfather’s old house. While exploring the upstairs study one night, she and her friend Melody accidentally unleash a flirtatious demon named Lyria, who spent the past fifty years in a stone.

After freeing her from her prison, the two become attached by a ‘lifestone’, which means Lyria can’t go far from Aria without feeling repercussions, and vice versa. Now Aria, an ordinary highschool girl, must find a way to free herself from Lyria, who seems to crave the exact opposite.
