Big Eyes, Small Mouth is a tabletop role-playing game that was designed to simulate the action of anime and manga. It is frequently referred to by the acronym BESM. The title alludes to the common anime drawing style of characters with huge, expressive eyes and comparatively small mouths. BESM uses a point-based character creation system. Characters are evaluated based on three "Stats", against which all action checks are made. These are supplemented by Attributes, which give the characters unique abilities.
