I guess this is probably the best place to put this question. My sister's ex-boyfriend claimed a 10th degree Black Belt in Eishun Ryu (apologies if I spelled that wrong) by the time he was 18 years old. His story is that his dad was stationed in Thailand, where he apparently did nothing but study Eishun Ryu 8 hours a day, every day, for a couple of years. At the time, my sister still liked the guy, so I didn't really question it. But it always seemed kind of fishy to me. Don't get me wrong, he has great martial art skills, and I don't doubt that he spent a lot of time training, but a 10th degree in a couple of years? My sister said his mom confirmed that he had a 10th degree, but it seems like that kind of rank would come with time, as well as training. Now that he's (mostly) out of our lives, I would like to ask of those who do participate in Eishun Ryu whether this is 1.) a plausible scenario, or 2.) If anybody else has seen this happen. See, we're finding out that the guy is a compulsive liar, and I don't want to get a wrong impression of this art, with just this one loser representing it. Thanks!
