I Am a Monster

Let go of that girl and let me do it! Before I finished speaking, I was hit against the wall... When I woke up, I was no longer human. I turned into a shemale - oh no, a half-demon... I can break the wall with one punch, and I can see the girl... Well, my nose is bleeding. Where should I go from here? Use this power to help humans manage the world, or desperately strive for power, plunder wealth, and trample everything under your feet? In fact, I just want to live an ordinary life, date a beautiful girl, and form a happy family...
