The Japanese government really needs to start administering psychological/background exams before issuing visas. Or even just a basic IQ test. But then NOVA would've been incredibly short-staffed in the 90s and 2000s. I'd wager a bet this guy is a sociopathic virgin who enrolled in the Ritsumeikan exchange program over in Beppu thinking he'd finally get laid, discovered otherwise and has now taken the hunt online. Hooray for reopening.
