Kiiru

Kiiru, most known as Captain Yellow, was the captain of a riverboat, the Bullfrog, that moved legal supplies between the City of the Rich Frog and the Scorpion Clan Palace at Ryoko Owari Toshi.

Patron
Her patron was Shosuro Gobei. Yellow guessed Gohei had smuggling activities, but never with her. She believed her boat was the perfect decoy to counteract her patron's ilegal activities. This is why she left town whenever there was an intense manhunt; staying on the “suspicion list” of Emerald Magistrates she probably helped the targets of these manhunts got away. She did not know that Gobei was a truly honest patron, without any hidden activities.
