Binchotan has no parents, with a piece of charcoal on her head, living alone in the depths of the mountains (applauding for charcoal becoming a萌element =V=). She often goes down the mountain to the town to help people work. The residents give her food as a token of gratitude, and Binchotan lives her life with great effort. Binchotan, who brings warmth and happiness to the residents, also makes one good friend after another. There's the cooped-up rich man's daughter, Raccoon Charcoal, the lively girl who loves inventing and lives with the medicine man grandpa, Bamboo Charcoal, Bamboo Grove, Bamboo Charcoal's little sister who always follows her around, and the amazing power-possessing Smoked Charcoal... With these cute little loli, heartwarming stories are about to unfold one by one.
