You transmigrate into a noble family. The heir who once cherished you, your older brother, has died in battle. The family is beset by internal and external troubles, and an astronomical debt hangs over you. The year is just past 2000. Think this is a story about a transmigrator using their knowledge of the future to inherit the family and make a fortune? No. Let me tell you, my brother’s name is Kayneth, Kayneth El-Melloi Archibald.
