There's rarely a dull moment when Chika Ito and her friends get together: whether they're telling ghost stories, playing games, or taking trips to the beach and park, every day brings a new adventure. Of course, not everyone appreciates the constant presence of a pack of 12 year olds, and Chika's big sister Nobue might sometimes wish that Chika's friends weren't always underfoot. Especially troublemaking Miu, whose "help" with Nobue's job hunt is definitely not appreciated! Then again, Miu can cause problems just about anywhere, even when she hits her head and thinks she's in Heaven! And when the girls make a trip to the public baths, does anyone think they'll make a clean escape and scrub away every single piece of evidence? Either way, the funs sure to continue as the whole gang reunites in the complete OVA collection of STRAWBERRY MARSHMALLOW!
