I don't know the exact main characters as I'm not familiar with this specific novel. But they could be the weapon maker themselves, perhaps a young apprentice learning the trade, or an experienced master.
There's no way to be certain without reading the graphic novel, but perhaps the main character is an apprentice star maker. There could also be a mentor figure who teaches the protagonist the ropes of star - making. And there might be antagonists, like those who want to use the power of star - making for evil purposes.
The antagonists can also be popular in King's Maker fanfic. They create conflict and obstacles for the main characters, and their motives and backstories can be explored in more depth in fan - created stories. For example, a power - hungry noble who will stop at nothing to gain more influence.
Since I don't have detailed information about the 'Star Maker AI Graphic Novel', I can't say for sure who the main characters are. They could be scientists or engineers who are involved in the development or control of the AI for star - making. Or perhaps the main character is the AI itself, with other characters being either its allies or antagonists in the story.
I recommend " My Wife Has Arrived, President, Please Sign For It " to you. The female protagonist of this novel is also a designated driver, but she not only deliver goods but also does some odd jobs sometimes. She opened a cake shop with her friend, but later she met the male lead, and there was a long love story between the two of them. I hope you will like this novel.
Well, it's a bit of a mixed bag. Some people find Visual Novel Maker really useful and enjoyable, while others might struggle with it. It really comes down to your specific needs and how comfortable you are with the interface and functionality.
