It is introduced as a bear cub, but in fact, it is not known whether it is really a bear cub. There is a trademark red button on the chest, but when it came off, it was explained that 'it should be sewn on,' so there is a slight possibility that it could be a mascot costume.

It is described as having come from nowhere, with a mischievous and innocent personality. It plays little pranks on the members it lives with every day, but it's gradually maturing, like using a water-based pen when drawing graffiti, showing it's climbing the stairs of adulthood.

Loves sweet things, especially strawberries, apples, and cherries.
