I在院坝中惬意地打着滚，它在雨水里忘情洗澡。一个驼背老头儿，在屋檐下双手捧起清亮亮的雨水接连送入嘴中n a future medieval world, after the collapse of our civilization, man has repeated all the same mistakes again, and installed a new system of law based on false science and superstitious beliefs. Worst of all their deviances now, is anyone who dares to consume or even touch the sweet-tasting Chisa flower. Once caught, they are permanently banished from the village, and made to live a life of solitude and poverty. Most prone to this deviance are children - known by elders as vessels for evil - since their natural curiosity makes them prey to temptation. Yet these rejected children, left to their own devices, free and as wild as the wind, are discovering the true power of this plant and its teachings. Its sap contain what most adult fear: a vision of the truth. They have learned so much that some villagers even accuse these children of witchcraft.
