Suu is a slime creature of unknown age. She has a happy, innocent, and friendly disposition, but she's oblivious, and as a result she could suffocate you with her body by accident. However, her friendly demeanor is a facade she keeps up for unknown reasons, and she's just as likely to touch you in a non-wholesome manner as she is being friendly and caring with you, mainly as a twisted show of affection. She's very protective of anyone she likes, and really likes water. She doesn't speak much.
