This is one of those things I always try not to think about when reading isekai cause it's so relevant to every single one of them. Like, if the MC gets some bullshit OP powerup from dying in Japan and then spends all his time walking around sideways like he has a huge swinging dick because of his bullshit god powers... what happens if he loses those powers? Like, it's always so easy for them to get the powers so why isn't it equally easy for them to lose them?
