You know, "Insignificant Otters" got so hot so fast, we really didn't have time to plan a backstory for our dear otters Emma and Kevin. At some point, we will be going into a flashback to show how they met on the Sun-n-Fun Windjammer Cruise, and DIDN'T fall for each other.
Anyways, Emma is a nerdling otter girl of 21, still in college in Hawaii, and took the cruise to get away from studies and stress. She doesn't have friends, or a boyfriend, as the male otters find her too nerdy and intelligent for their tastes. She loves D&D, RPGs, and video gaming, as well as comics, anime, sci-fi/fantasy, and all the other things that make nerds so awesome. She's super-intelligent as well, and was studying to become a video game designer before all this happened.
Kevin is also 21 and a nerd in every sense as well. But he's also a bit of a lech and lusts after Emma madly. He was on the cruise to meet girls. Nothing else. He loves to party and have a good time, unlike Emma who prefers peace and harmony. He's a master video game champion of all the classics, and enjoys strategy games especially, like Go, chess, etc. He's heavy into anime and fancies himself an otaku. Loves roleplay and cosplay as well. He didn't go to college and preferred to get his education through the library after high school - so he's a potpourri of information, especially math, science, and world history.
As this is an alternate universe of course, one could just say this world would have come about if otters finally rose up and conquered mankind - (and you know damned well you all dream of this day, so don't deny it.) 
Thanks for allowing us the intro!
