Cologne

Cologne is the great-grandmother of Shampoo. She accompanies Shampoo on her return to Japan, and opens the Cat Café in Furinkan. She is a contemporary of Happosai, and well over one hundred years old. She calls Ranma "bride-groom" and "son-in-law" due to her attempts to have him marry Shampoo, and just to watch him become enraged. She is a grand master of martial arts, and occasionally teaches Ranma and his rivals new techniques. She gets around by pogoing on a gnarled wooden staff that she sometimes uses as a weapon.
