Reincarnating as a demon in sousou no frieren

I tried to identify the rocks I found, and with my improved memory and prior knowledge, I was able to recognize some of them. I wasn't an expert in geology, but at least I now had an idea of what kind of materials I had on hand. With that in mind, I started thinking about the fauna of the place. Would the universal laws be the same as in my previous world? That was something I would have to verify over time. For now, I focused on what I could do here and now. 

Exploring further, I found dry branches and a piece of flint. That's it! I could try making fire, which would be crucial. Also, near the mountain, I found a river that seemed to have clean water. Additionally, among the rocks, I noticed something shiny: obsidian. It could be useful. What could I do with it? 

I collected as much as I could and started on the challenge of making a primitive knife. I took the obsidian and struck it with a rock, but initially, it broke in half. Was it the force I applied or the technique? I wasn't sure, so I decided to try different approaches. I tried applying more force, adjusting the angle of the strike, and even using different stones. Thanks to my knowledge and some experimentation, I finally managed to create a primitive knife. 

Looking at the tool I had created, I felt incredibly proud. It was something simple, but I had made it myself, and that meant a lot. Although it was almost nightime, I knew I should return to the cave. I had spent longer than I thought.

Before I returned, I walked over to the river to see if I could do anything else. It was then that I saw myself in the water and noticed something I hadn't considered. Is that boy reflected in the water me? I looked at myself closely, seeing an effeminate boy with long, unkempt pink hair and horns like a goat's. Was this what I had become? A demi-human. I stood there for a moment, shocked by the reflection. It wasn't what I had expected, but there it was, right in front of me. 

Is this who I am now? I didn't have much of an idea of what to expect, but there I was, with these horns on my head and a body that didn't feel entirely mine anymore. Is this part of an evolution? Perhaps a natural change due to my new form, this new world. But something inside me was also pondering: Could it be that I look "cute"? 

I couldn't help but smile a little. It wasn't exactly what I had planned for my new life, but in a way, it was me. That boy reflected in the water was my new form, my new identity, and I would have to accept it. 

After a few moments, I stepped away from the water, returned to my task, and began cutting some grass with my knife. Although it wasn't perfect, what I had done was a good start.
