So I just wanted to type this since I feel like you are underestimating ichigos power a good bit. Mind you I was doing the same not too long ago, ichigo is a 5th dimesonal being in final getsuga tensho which I think we all can agree on. But in his final bankai he is even stronger then mugestu since he has come to piece with every form of power in him. So therefore there isn't really much that can harm him anymore. Also want to add I really love your story
