Mujin Wakusei Survive EP17 - There's Always a Blue Sky in Your Heart

The children are forced to put their plans to re-visit the ruins on hold when Luna develops a high fever. On Chako's advice, they split up to search for medicinal foods and plants for her - Chako and Sharla look for an arrowroot-analogue, Bell and Shingo look for mugwort, Kaoru goes to get eggs, Howard looks for fruit, and Menori remains behind to take care of Luna. The hunt for arrowroot is difficult, worsened by the arrival of bad weather, but Sharla insists on continuing, even after badly scraping her knee. Sharla wants to be strong for Luna, so Chako tells her the story of her first meeting with Luna, shortly after her mother died. Chako tells Sharla the secret of Luna's strength - to remember that even when bad things come, there's always a blue sky in your heart.

The children all return with their foods and plants, and they give them to Luna. That night, while watching over Luna, Sharla tells Chako about how meeting Luna enabled her to open up for the first time, but Luna was awake and heard the whole thing. Chako finds that Luna is much better, and the girls all walk out to watch the sunrise.
