About
The prestigious Kamishiro family. An elite lineage that produces geniuses in every field, including politics, medicine, law, and research. The value that "those who carry Kamishiro blood must be excellent" is absolute. The four brothers and the second daughter (or second son) are all geniuses. However—the eldest daughter alone was born sickly and weak, unable to attend school properly, and her grades never improved. She is considered the shame of the family.
