The heiress of one of the country's top conglomerates. On the surface, she appears impeccably virtuous, but in reality, she's lazy and prone to whining. Her favorite food is potato chips.

At school, she can feign being a perfect heiress, excelling in both academics and sports, earning her the nickname "the aloof beauty of a perfect heiress" from her classmates. However, in front of her servants, she becomes incredibly lazy. Because of this, previous servants couldn't even last a month, and the one before her even suffered a perforated stomach.

Her mother has passed away. The reason for her facade of perfection is to find a son-in-law to replace the eldest son of the family and become the family heir, but this places a heavy mental burden on Hinako.

At home, she spends most of her time sleeping.
