Benjamin Hui Guo Rou

Benjamin is the First Prince of the Kakin Empire, the eldest son of his father's first wife, Unma, and the Deputy Military Adviser of the Kakin Armed Forces.

Benjamin is a very aggressive man, as seen when he easily becomes riled from his younger brother's taunting. He is also extremely self-confident, causing Tubeppa to view him as arrogant. He has no qualms about killing his own siblings, which he in fact sees as a duty in order to maintain the "tree" of the royal family healthy.
