When Ritsu’s friends from Junior High invite the Keion-bu girls to perform with them at a concert house, it’s time for After School Teatime to get rehearsing. With only ten days to go until the gig on New Year’s Eve and nothing prepared, the band must decide on their playlist, costumes and even their lighting. While everyone is excited about their first public concert, will the five girls be able to overcome their nerves and insecurities to make their big debut as incredible as they all hope?
In present day Japan, the life of a school girl is never dull. The easily-bored Konata never finds time to study because of her otaku habits, which frustrates hard-working Kagami to no end. On the other hand, laid-back Tsukasa always manages to go with the flow, while Miyuki is concerned with keeping her status as resident know-it-all. Join these four girls as they muse and meander their way through everyday events such as eating chocolate cones, doing homework, gaming, and trips to the beach galore.
