New mini anime series for , part of the celebration for the franchise's 24th anniversary next year.

A comedy about a family of old-fashioned samurai living in modern-day Tokyo whose young son has to head out for an important date.

Kaname Okiura, a student of Prefectoral Umineko Shougyou High ("Umishou" for short), joined the school's swimming club in order to learn how to swim, but the club is filled with weirdos, let alone who can teach him swimming. Then, a sunny, happy-go-lucky girl named Amuro Ninagawa who transferred from Okinawa joined the club. Her extraordinary underwater speed and unorthodox swimming style (plus her personal habit of nude swimming—a powerful magnet to teenage boys) surprised every club member, especially Okiura, because she reminds him of a mermaid-like creature he saw only once in his early childhood.

Fifteen-year-old Chacha is a typical teen with an atypical talent: she can communicate with cats. Though her friend Mito thinks this is the coolest ability in the world, Chacha finds her unique skill to be annoying at best and disruptive at worst. Whether she's dealing with countless strays proposing marriage, neighborhood cats offering to help her with tests or waking up to 'presents' on her bed in the night, Chacha's normal school life will be anything but!
