Todo's appearances in the JJK manga are scattered. It depends on the specific storylines and conflicts. Sometimes he's in the foreground, and other times he makes cameos to add to the overall narrative.
I recommend the following novels to you. They are all completed comics:
1. "The Great Pirate Krokdal": This is a Doujinshi novel about the pirate king, Sand Crocodile. It has been completed. The plot is a bit behind, but it is still worth reading.
2. "I Want to Evolve": This is a futuristic novel. The protagonist has transmigrated to the end of the world and obtained the ability to evolve. It has ended.
3. "Comic Queen's Collection": This is a doujinshi derivative novel. The protagonist is hypocritical, seductive, beautiful, but extremely cold. It has ended.
I hope you like my recommendation. Muah ~
