Sister Yolanda is the leader of the Church of Violence, often called &quot;the Rip-off Church&quot; by much of Roanapur. Located on the mainland of Thailand, the facility operates as an active Roman Catholic church &ndash; although it is heavily active in arms and drug smuggling, and often undercuts operations by the other Roanapur mob syndicates, including Balalaika&#039;s &quot;Hotel Moscow&quot;, but has remained unattacked by them because of their religious status.  Although kind and soft-spoken, Sister Yolanda runs the Church of Violence with an iron fist, and is the one person that can barely keep a hot-head like Eda under check. She is also appreciative of the talents of Rock, when he let on about his observations about the drug smuggling operations of the church and kindly made mention how it would affect the relationship of it with the Lagoon Company. Just in case things go wrong, she has a golden Desert Eagle automatic pistol hidden in her desk, just in case.

Okajima Rokuro is a Japanese businessman in a town full of Japanese businessmen. His normal day consists of social drinking with clients and being kicked around by his bosses. He finally gets a break though, as he's sent by his company to the tropical seas of Eastern China to deliver a disc. But his boat gets hijacked by a band of mercenaries hired to retrieve the disc. Rock (as he is newly dubbed by his captors) catches the interest of the only female merc Revy as she thinks he's worth a ransom, taking him hostage. However, the disc that was stolen has a terrible secret that's unknown to Rock, which causes massive confusion and chaos for both him and his kidnappers.

Originally born Kinue Takeguchi (竹口絹枝) in Hiroshima.

Canadian stage actor. Best known role outside of anime is the villain Hexadecimal from Reboot.

Okajima Rokuro - now known almost exclusively as 'Rock' - was once a typical, put-upon Japanese businessman. Then, on a routine business trip, he was kidnapped and ransomed by the Lagoon Company: a band of mercenary pirates operating out of the crime-riddled city of Roanapur. Abandoned by his bosses, he joined the Lagoon Company. Now he must try and stay afloat amongst the ever-shifting politics of the criminal underworld, while simultaneously avoiding death at the hands of his quick-tempered, gun-toting co-worker, 'Two Hand' Revy.
