In a school where all students are required to participate in after-school activities, Hajime and her buddy Sayo come upon a new club that they have never seen before. The club's name is "The Cultural Activity Preservation Club," and as the two enter the room, they find a variety of analog professions and activities, such as handcrafting mats and toothpicks. This is Double J, a unique culture animation blended with humour to keep you entertained.
