I appreciate your feedback. You and others are free to comment on my work, after all, this is my first project and it will certainly have its flaws. I understand what you're saying, but I'm not going to leave the main character without depth. He has a backstory that will be gradually revealed as the narrative progresses. In chapters 14-16, Kaito's story will be partially revealed. As for the secondary characters, I'm aiming to develop them better, but I don't want to drag out the first arc too much. But I'm working on it now because I want to build a solid foundation before starting the second arc.

From a legal and moral point of view, there will be no problems. The most important thing is to develop the characters' personalities and build their relationships. You can google "Japanese man married four girls for money", there is an option to build a harem in real life

Thanks

Thanks for the comment, there were some mistakes in the text that I didn't see. About the com, there are coms after some of the characters' lines because a dialog tag follows it. At the end of the 5th chapter, I wanted to convey the friendly communication style in Messenger. I'm not a native English speaker and I don't correspond in English that often, so I might not have gotten it right. I added more clarity to the text and corrected an abbreviation mistake.

When coming up with the abilities, I was inspired by Superboy. Kaito's abilities are not a complete copy, but they are pretty similar.

This will be explained in detail in later chapters

You could just say, take all the girls

At least...

You and everyone who liked you are clowns. You read a Danmachi fanfic and insult someone who likes the harem by calling them a salty soy boy? You hate a harem, and yet you're reading a fanfic based on a ranobe with the harem genre. What kind of dumb bastard would you have to be to read\watch a harem and insult people who like reading harems

After receiving so many comments about how good this fanfic was, I decided to give it a try, but seeing how the main character gets resistance to mind control due to his big ego at the beginning made my desire to read more drop a lot. I don’t know what will happen next, but seeing such a scenario at the beginning, there is not much hope for something worthwhile
