From a Certain Point of View: Jessica firmly believes that the noises she heard her mother and Toshubi made in the kitchen were the sounds of them "wrestling" and nothing more.
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).
Human Popsicle: Every human on the Arks. They're waiting for the Nanovirus to die off in 300 years, which translates to "two years awake-time".
Inevitable Waterfall: Toshubi goes over one while fleeing the feline palace guards.
I Don't Like the Sound of That Place: The Toshubi World Map shows an island in the center of the remaining landmass, which is shattered into micro-continents, labeled "Disease Island".
Intangible Woman: The wizard the Emperor hires can walk through walls.
Ruins of the Modern Age: The Test of Stealth requires one to evade giant worms that have taken over an abandoned missile silo, and one pinup shows Toshubi Above The Ruins of a pre-war city.
Scary Shiny Glasses (Toh does this often. His author is learning to do this)
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".
