In a world where artistic expression takes physical form as magic, Hoshigei Academy exists to help students cultivate that ability. Aigasaki Kohana enrolls as a second-year student, following in the footsteps of her late mother—a flower arranger whose work left a permanent mark on Kohana's sense of what art means. As she learns what it truly means to be an Artista, she finds more than technique: friendship, and something that might become love.
