Bincho-tan (Binchōtan) is a mascot character created by mangaka Takahito Ekusa and produced by the game goods company Alchemist. The name is a pun: binchōtan is a type of charcoal primarily used for cooking. However, the suffix -tan stems from a mispronunciation of chan. In line with this wordplay, the main cast consists of moe anthropomorphic representations of various types of charcoal.
