Soul Street was a manga with superpowers as its theme, in which all the characters had unique abilities. There were only two female guardians in the entire manga, and the rest were male. This could be due to the following reasons: 1. Gender-restriction: In comics, the genders of the guardian spirits are usually limited to male or female. This could be due to cultural traditions, religious beliefs, or the author's personal preferences. 2. Character setting: In some cases, the author may choose to let the guardian spirits have different genders or personalities to better express their characteristics and character relationships. For example, in " Soul Street ", the female guardian spirit Xia Lingling and the male guardian spirit Zhang Hao had a special relationship. 3. Creation inspiration: Some authors may choose the gender settings of the characters from different perspectives or inspiration sources to create a more unique storyline and character image. The gender restriction of the guardian spirits in the street of souls could be the result of a combination of many factors. No matter what the reason was, this gender setting added a unique charm and style to the work.
