Ramba Ruu
Sometimes spelled Lamba Luu. "Brother" to Amalla and Kaolla. In reality, he is a cousin of theirs, but they have grown up as siblings. He is the king of their nation, and in the tradition of their people, he has to serve in the military for a period of time. Before that happens, he is required to marry. Once when Kaolla was a very young girl he promised to marry her but then he thought she only saw him as a brother and Amalla does not, he marries Amalla instead.
Ramba Ruu looks almost exactly like Keitaro when they both have their glasses on; the only striking difference is that he's a bit more tanned than Keitaro is. Unlike Keitaro, however, Ramba Ruu is very calm, collected, and 'together', and not at all clumsy or awkward.
