A young Nobunaga and her mother were arguing because of Nobunaga's rather troublesome behaviour. Nobusada told her daughter that she could teach her granddaughter a lesson and that she should put her trust in her, she toke Nobunaga for a horse ride outside whilst it was raining she gave Nobunaga some important advice and gave her a smoking cane which she can often be seen gripping onto throughout the anime.
