Treasure Hunter Warning! - S1.E35

Sakuya and Kaguya appear on TV with Aine and her friends before being given the task of producing a video tour of their home. Aine and the others offer to help and end up discovering a treasure map that leads to some treasure the twins buried when they were younger. The girls feel that going on a treasure hunt and filming it would make a much better video, but Sakuya and Kaguya are reluctant to go and find what they buried.
