Fuente: AniList

Hibino Yua is an idol who does singing jobs and models sexy photos. She pretends to play the role of a pervert, causing many of her fans to send gifts like vibrators and other sex toys. However, that pretense leads her to become entangled with a pervert who possesses a magical device: his smartphone, which has magical powers that allow him to perform movements or touch things without touching them directly.
