Cute High Earth Defense Club Haikara!

The Earth Defense Club at Mayunan High School consists of five ordinary boys - Unzen, Sukayu, Unohana, Oshamanbe, and Aso - who spend their days lounging in the clubroom and living together in the Kurodama dormitory. One day, while taking a morning bath, they find a talking Pallas's cat named Nuru in the bathtub, who claims to be from the future and warns them of an impending threat to the Earth. The club members are initially skeptical, but eventually decide to take action and are transformed by Nuru into the Fashionable Romantic Troupe using advanced feline technology.
