Mahou no Shimai Lulutto Lilly

Fuu and Rui Nonoyama are sisters from a magical land, but lately they have grown distant from each other. When two cat-like spirits grant them the power to transform, each girl secretly steps into a new life as a magical idol, all while keeping the truth hidden from everyone around them.

Their magic comes with strict limits: it will last for only one year, and no one can learn that magic exists. Blending school days, family life, and bright idol dreams, the story follows the sisters as they chase the grown-up selves they admire without realizing they are sharing the same secret.
