The upper part of the chapter is filled to the brim with errors, while the middle and lower is better there are also some errors but nothing too extreme, still want to correct this one error here:
*Even if I fought Eizou 100 times, I wouldn't win once.
So it's not that she fought him already 100 times and only won once but "even if" so their fights weren't skipped they never happened and she never managed to beat him.
