Yoritomo Ryuuji
The eldest boy adopted by Yoritomo Katlynn. He was a peasant boy she picked up out of one of the towns.
Ryuuji adapted pretty well to the life of a Yoritomo, and has enjoyed himself at sea as a pirate and a tradesman, but wasn't chosen to take on the mantle of Clan Champion. He is just a little bit more cynical, and a lot more hot-tempered, than his brothers.
He met Yogo Megumi while he was checking on a caravan in Toshi Josho. A few strange occurrences where she kept being in front of him in her underwear caught his attention pretty fast. Trapped together for a few days, Ryuuji decided to take a chance on seducing her, and found her at least unable to tell him no, if not amenable, despite being betrothed to the Governor.
