Well, the dub could be funny because of the unexpected twists in the dialogue or the way the characters' personalities are emphasized. Sometimes, it's just the chemistry between the voice actors that brings out the humor.
Among the search results provided, there were a few funny transformation novels that were worth recommending. The first was "The First Chaos in History"(Author: Zhang Xiaohua). This novel was famous for its nonsensical style and funny plot. It was considered a classic in the world of comedy. In addition,"God of Europe"(Author: Chen Ji, Tang Hongdou) was also a funny novel. It described the unparalleled good luck that the protagonist obtained when the world was transformed by Reiki. There was also "What If I'm Too Popular"(Author: I'll Add Mushrooms for You). This novel was mainly about manga-style interpersonal relationships and the story of poisonous chicken soup saving the villain. In addition,"The Transformation Game" and "The Strongest Crossdressing System" were also recommended by the two funny female protagonist transformation novels. In general, these novels were all featured by a funny and relaxed style, suitable for readers who liked to turn into funny stories.
I think it's worth watching. The voice acting and the way the story is presented in the dub make it an interesting watch. However, it's not a perfect adaptation and has its flaws.
