Riko
Riko is a pumped up, excited, and an expressive woman to the CORE, a wild boar of a woman that has a little soft spot for little/weaker things. She's a big ol' dummy as well, not knowing complex dialect and even has some trouble with some 4 syllable words. She sometimes calls people by nicknames on what she judges people by, like calling her Chinese friend who does kung-fu "Jackie-chan" and other things like that. Just think of her as a goofy boar, dangerous, but kinda stupid here and there. Riko likes to cheer people on even if it's someone who beat her in a fight, only hating people if they actually do something outside of fighting. Though Riko basically has a second personality when it comes to fighting though, she still keeps her little goofy attitude only with her words though, she has a RUTTHLESS personality when it comes to fighting, never wilting no matter how much damage she takes.
