I randomly stumbled upon this while I was looking for VNs which had similar aspects to the VN I finished yesterday, so I decided to give it a shot.
Though I'm not familiar with the game Black Survival, the story you created so far was intriguing and quite well done. I do however did notice a few typos, but that's only to be expected due to it being a beta version.
I am looking forward to where you'll be taking this project and how the story shall unfold.
