Pirates and the Song of the Knights of the Heavens

In a certain time and space, five world wars occurred and the entire world was on the verge of destruction. At this time, a little girl had just become the Kamen Rider of this world. His journey to save the world has not yet begun when a pink weirdo suddenly appears and talks about something strange, such as destruction or something. Then there was a flash of white light. At the same time, the traveler from another world was suddenly hit by the soul of the knight when he was heading towards the pirate world. The two souls merged. As a result, both parties lost their memories at the same time and came to a pirate world as a mixed soul. A new story unfolds Zoro, stop it, don't touch my immortal sword Akainu, eat me and give me a knight kick Luffy, I've said it many times, the belt is a combat item, not a child's toy. Don't ask me to transform you again. It's not an invincible style + the protagonist's personality is a bit like Robin + although there is no female protagonist, it's mainly because the male and female protagonists may be the same person. This is the author's first book. Before this, I had never touched writing at all. I wrote this book completely on a whim, so the content may be very messy, okay, it may be terrible, so feel free to read it! Of course, it would be great if you could give me some appropriate advice. Thank you very much!
