If there're not on .com's list and you can't find them on Reddit (seriously, that's not picked up by my spell-checker, whereas real, obscure words are?!), then you're basically out of luck. You could always try different sites, forums, etc. There's some popular site where the Japanese players hang out, I hear (no, I don't know the name of the site).I've already checked .com's list and have had no luck finding any of the matching ones on it, probably should've stated that lol.
Looks like you'll just have to re-breed, then.
