Umbriel, even though she is one of the youngest of our group, she is very laid back and calm. She is not very social like Miranda or Ariel either, but unlike them, she does not seek attention at all. She tends to always keep to herself, being more focused on her own ideas and interests. She is quite the smart one, however. She is actually rather friendly to people she meets, and she is quite caring as well, and is probably the most mature moon of Uranus Chan.
