Demon Slayer: I Am a Dragon Lady, You Want Me to Fight Without Mercy?

This is my first time for a newbie to write. Updates will be very slow, so don't complain. I didn't win, my phone was confiscated and I won't update until summer vacation. Sexual transformation + invincibility + no sword + self-created breathing method + Demon Slayer: Kimetsu no Yaiba I can't write the introduction, so just read the text. The front may be a bit short, but the back won't be short. I will try to make it longer.
