It's not just a "You can't really now where you will end" is more like "motherfucker you don't even know if she went to other world or just fucking died"
I totally understand saboru's mentality of "i have family and shit and I need to at LEAST now that there's a way for me to go back with them" but bro let me tell you one thing, if I'm not an insanely broken character on the level of fucking gods I'm not even risking my luck attempting shit and just doing my best to live a life as decent as possible. Because there's 0 chance I'm gambling my body/soul or whatever getting destroyed in the process of changing worlds
