Suu

Suu is a slime-type monster girl whose body is entirely composed of liquid matter. She originally slipped into the protagonist's home without permission while searching for a water source. Her physical form can expand or contract based on how much water she absorbs, which also affects her cognitive abilities. Naturally inclined to observe and replicate the behavior of those around her, Suu initially had little understanding of common sense or language. However, through daily life with her new housemates, she reveals a remarkable capacity for learning and develops a heartfelt bond with her host.
