Yotaro's mother

Yotaro's mother (ママン) is the long suffering mother of the sickly Yotaro.

Overview
Yotaro's mother has long hair, tied halfway by a large white ribbon, which reaches to just above her waist (slight brown in the anime) that also covers most of the left side of her forehead. She dresses in a long dress which covers her whole body (in the anime, the sleeves of her dress also covered all of her arms below her wrists). Yotaro's mother also wears a necklace, which was altered slightly in the anime to include a gold/yellow.

History
After giving birth to her son, Yotaro's mother became more concerned about his wellbeing when he continuously refused to leave their home to play outside like any other child would. As the years went by Yotaro's mother's desperation to get her son to go outside grew until she had all but given up hope of ever seeing him playing outside.

Yotaro
One day Yotaro told her that if she got him a panda he would go outside. This though overjoyed Yotaro's mother, but was soon replaced with more despair when she wondered just where she would find a panda. However, this all changes when Yotaro's mother finds Genma (who'd gotten lost during a training journey with Ranma) in his panda form on a cliff. Yotaro's mother then took the newly dubbed "Kumahachi" back home where he happily began playing with Yotaro, unfortunately, "Kumahachi" ended up not leaving the house either and the pair just sat around eating all day.

About a week afterwards, Ranma appears to take Genma home after searching continuously for him. Yotaro's mother is disappointed that the owner of "Kumahachi" has returned, but does note that she always expected this would happen eventually. Once she finishes explaining her situation to Ranma, Yotaro's mother indirectly blackmails Ranma into helping to get Yotaro outside as otherwise she'll have to pay for all the expensive food "Kumahachi" has eaten during his stay with them.

As Ranma struggles to get Yotaro to leave the house, Yotaro's mother decides to take a walk along the beach outside their home. After sending most of the day there, Yotaro's mother is shocked to see that, as the Sun sets over the horizon, Yotaro is running along the beach in pursuit of Ranma and "Kumahachi" like any other child. Overjoyed, Yotaro's mother falls to the ground as Yotaro and Ranma run out of sight...
