Ando used to run with Yujiro back in the day, but these days he's basically a hermit living deep in the mountains. We're talking serious wilderness—the kind of place that would kill most people. But Ando's a tank of a guy, built like the yasha ape itself, so he actually thrives out there.
His training routine is about as straightforward as it gets: eat massive amounts and chop wood with a heavy ax, over and over. Both his body and mind are just built different—the kind of mental toughness you need to actually survive in complete isolation. Most people couldn't even make the journey to reach his place, let alone stick around.
