Son Ryouou

Son Ryouou (孫 陵王 Son Ryōō) is the former Governor of Ran Province and current Minister of Defense.

Personality & Characteristics
He is an easy going man who is always seen smoking a pipe. He is Ou Ki's best friend and very loyal to him although he likes to tease him just like Ryou Anju does to Ki Kouki. He is a man of extreme strength who was able to cross swords with emperor Shi Senka, General Shiba Ryuu and General Sou Shungai at the same time and fought them equally. Kou Shouka referred to him as the 'Sword Sage' of the Son clan and only believed the story about him battling those three great fighters because he was able to sense Shouka's presence when he was hiding as an assassin.

Plot
He is a member of the Son family, a retainer to the Koku Clan. His family was purged during the previous reign. Since then he allied himself with Ou Ki and cut all ties to the Koku clan.

Ou Ki
He met Ou Ki at some point after his family perished. He allied himself with him and soon became best friends. When the previous emperor Shi Senka rebelled and invaded Kiyou, he and Ou Ki were one of the few people on the side of court and opposed Senka from the very beginning and to the very end.
