Review Detail of Nanakawaichan in The Author is an Extra, The MC is a Reincarnator

First of all, what caught my attention in this novel is the Main Character and plot. The Main Character is unlike the others. He wanted to make the main character (a reincarnator) suffer to save the world, it seems. The Main Character is not only strong, but also cunning. He always plan almost everything ahead, and didn't solve everything with brute force. He's strong, but not too overpowered. The plot also hooked me with its new take from this kind of novel. It doesn't only circling around the Main Character, instead all character and their thought are fleshed out, so we can understand the plot better. It also doesn't revolve in one place, a dungeon, or something. It's honestly interesting. The writing is also good, as the author said he has 4 editors. The update stability is daily with the chapters length longer than most novel in this site
