I’d like to believe that the way to get to that secret area is not yet implemented in our version. Their secret area has some kind of cube, which is absent in ours. And there is a legit way out too, which, again, is absent in iTOS. So to get there without being a Kino or getting teleported, you probably gotta wait until that makes the way to us.
PS: Yes, I tried to go there and check myself, but nothing happened. Oh and the hidden trigger thing shown in this thread earlier are just triggers that randomly spawn monsters if you near them (you know, those ambush moments where monsters drop from the sky).
