Iapetus Chan is the third largest moon of Saturn, and she is the most distant of the major moon chans of Saturn Chan. She is quiet and usually self reserved, though she is usually never nervous and she is quite brave. Her fellow moon girls describe her as possibly the quietest yet the most bravest and headstrong in the Solar System, even more brave and headstrong than Sun Chan. Iapetus Chan has quite the reputation despite her just being a moon!
