Yukishiro Taro

Yukishiro Taro (雪城 太郎) is father of Yukishiro Honoka. With his wife Yukishiro Aya, they work overseas as traders who buy and sell jewelry. Since they can't let Honoka come along, they leave her Grandmother to take care of her while traveling. They visit Honoka in her birthday's. They are strict and stern people, but when they see or near Honoka, they show their adoration and get mushy on Honoka which is delighted and uncomfortable to her sometimes. She misses them as they misses her.
