Kosu is a pretty little she-Toko who is very innocent and sweet. She wants nothing more than to please her handler and do a good job. Kosu despises violence due to taking a life and the "mess" it makes. However, she isn't afraid to get down and dirty when it comes to exploring. Oftentimes Kosu will dissapear only to return with what her handler calls "treasures". These "treasures" can be anything from a particularly large stick to an unlucky turtle. Since she is such a kind soul, Tokotas male and female alike are magnetically attracted to her for companionship. Although sociable, she sometimes prefers to sneak off to explore by herself.
