I recommend "Naruto: The Hundred Flowers Emperor" and "Naruto: The Best Movie King" to you. They don't have a female lead and don't have too many conspiracies. "Naruto: The Hundred Flowers Emperor of Thought" told the story of the Emperor of Thought's skill system integrating into Naruto, while "Naruto: The Best Movie King" told the story of Shikamaru's transmigration as the main character. Shikamaru's IQ was extremely high, and he had all kinds of schemes, but there were not many complicated schemes. It was very good to watch. I hope you like this fairy's recommendation. Muah ~π
