Sure, the Noragami manga is completed. It was a great ride with an ending that wrapped up the plot nicely. If you haven't read it yet, it's worth giving a go.
I don't know of any novel protagonist named Taro. Perhaps you're referring to some other novel or storyline. If you can provide more information or context, I will try my best to provide you with a more accurate answer.
" Five Blessings " was an ancient romance novel created by Zi Yu. The story was about a heroine who wanted to live an ordinary and happy life, but beautiful men came to pursue her one after another, giving her wealth or official positions, triggering a series of temptations and troubles. The novel was completed, with a total of 115 chapters. The readers can read the full text online on platforms such as Qidian Chinese Network.
Definitely not real. Urashima Taro is a classic tale from Japanese culture that's more about imagination and storytelling than real-life experiences. It's a wonderful story but exists only in the realm of fantasy.
