ILLIT doing the opening connects to global audience—the South Korean girl group performing "Bubee" brings K-pop appeal to the magical girl series. Sisters unknowingly being rival idols is perfect drama; Fuu and Rui debuting separately without realizing they're competing creates delicious dramatic irony. One-year time limit adds urgency to their story—knowing their magic expires puts pressure on both their idol careers and sisterly relationship. Original magical girl series from Pierrot is promising; the studio's experience with the genre combined with fresh storytelling shows creative ambition.

A main trailer and main visual were released for the Magical Sisters Lulutto Lilly anime before its April 2026 broadcast today. The original magical girl series' opening theme song, "Bubee" by South Korean girl group ILLIT ('Tis Time for "Torture," Princess Season 2 OP), is also previewed in the trailer.

The Story

The story of Magical Sisters Lulutto Lilly follows Fuu Nonoyama, an innocent elementary school student who is looking forward to summer vacation, and her older sister, Rui Nonoyama, a diligent middle school student who is modest and hardworking. Fuu and Rui used to be very close, but recently they've been growing apart.

One day, Fuu encounters a mysterious spaceship and is granted magical powers. Rui also acquires magical powers, and both of the girls gain the ability to transform into the adults that they've dreamed of becoming. However, their magic comes with two conditions: it only lasts for a year, and it must be kept a secret at all costs.

Unaware of their respective secrets, soon Fuu and Rui end up debuting as idol singers in their grown-up forms.
