The Kijima family, which is my parents’ house is a famous household. It seems to have originated from a great family, but it increased due to my father.
The reason is my mother. The Kasugano family, which is my mother’s family is a noble house, just like my father’s, and the marriage between my mother and father led those two families to join hands. Which increased Kijima’s power by leaps, my father having an amazing business ability might be the cause too though.
