Having an incredible strong female MC is cool on it's own. Having her being ridiculously strong and nice looking is even better. The whole Isekai/genderswap is almost irrelvant to be honest and just adds a bit of flavor to the character. The scenes where they all run together are great, having a very strong MC who is not a jerk is always cool. Her loyalty to her friends is hearth warming and nice to see. The MC girl should have gained muscles during her development/training. That would have made this anime really a masterpiece and would have been the key element raising it above other anime.
