Good People Have Good Sex: Toh's a sadist who is also into erotic roleplay. Toshubi and Betsy merely engage in some light frottage. Also: Raool and Mesi have one hell of a one-night-stand (missionary start to finish).
Sex Slave: Villagers deemed to be suitable for "entertainment," Toh's "Playthings". Subverted with Masato, he bought Eri from Doc to protect her, and has just gone AWOL to get her away from Kohi's "soldiers".
