Obviously, it's the girl in the title. Since the story is named 'Slowly Shrinking Ray Girl Story', she is the central figure.

I'm not sure specifically as there could be various interpretations. It might be a story about a girl who is affected by a slowly shrinking ray, perhaps facing challenges or adventures as she gets smaller and her world changes around her.
There was a girl. She began to slowly shrink. As she shrank, she found herself in all sorts of strange situations. She could fit into small spaces like the space under the couch. She made friends with a little mouse who was now the same size as her. The girl's shrinking made her realize how big the world really was. Every day was an adventure. She had to climb up the legs of chairs to get onto the table. However, her family was worried sick about her. They searched everywhere. In the end, a kind fairy saw her and used magic to reverse the shrinking process.
Perhaps it was a side effect of some strange experiment. She might have been exposed to a new type of chemical or radiation in a science lab accident that caused her cells to contract slowly.
Since it's the 'Shrinking Man Story', the main character is most likely a man who experiences the shrinking phenomenon.

In the 'slow shrinking woman story', the main character is likely the woman herself. She is at the center of the story as her shrinking is the main plot device. There could be other characters around her, like her family or friends who might react differently to her situation. Her family could be in a state of shock and try to find solutions, while her friends might distance themselves out of fear or confusion. All these interactions would revolve around the main character, the shrinking woman.
It depends on which specific comic series or storyline you're referring to. In some, Shrinking Ray survives, but in others, he tragically dies.
Based on the name 'ray first story', it seems that Ray is likely the main character.
Most likely, the main character is the woman who has the encounter with the laundry detergent and shrinks. But we can't rule out the possibility that there could be other important characters. For example, if it's a story about finding a cure for her shrinking, there could be a scientist character. Or if it's a story set in a family context, her family members could also play significant roles, but the woman who shrinks due to the laundry detergent is the central focus based on the title.
