I have read a lot of martial arts novels and helped me to name the characters in my novels.
In ancient times, you should have a name and font size. The name of the woman in killer darts is Ling Huyan. The word "Ruoxue" and "Yan" can show that his darts are as agile as swallows.
As for the man, he can be called Wu Yingjie, and the word "Ba Tian". Since he is holding a hammer, he should think of Li Yuanba in the Tang Dynasty, so it is better to have the word "Ba Tian".
