Erza (fairy tail), Kagura (gintama), Morgiana (magi), Mikasa (aot), Lady Bishamon (noragami), Sakura (naruto) and Rukia (bleach) are the strongest and best written female characters of all anime. Also gorgeous and inspirational heroines. I look up to them greatly.
A pregnant woman gives birth to her kid by suffering through what feels like squeezing a watermelon through her nostrils. Artists endure suffering that feels like pulling the entire universe out of their ass to create their works.
