Claire has light green hair done up in braids, red eyes and fair skin. She is seen wearing a purple coloured top with a frilly collar and has a band-aid on her left cheek.
Claire appears to be kind and compassionate, especially to bully victims.
According to John, she is somewhat manipulative when it comes to achieving her ulterior motives. However, it should be noted that she was trying to stop John because he had become a tyrant.
Claire attended New Bostin High School alongside John in class 2-B. At some point during John's time at New Bostin, Claire helped him out after the latter got bullied.  It was also revealed that she saw John's future as the King of New Bostin.
However, as time went on in New Bostin, John became corrupt. In order to stop him, Claire rallied the students of New Bostin against John. Unfortunately, John proved to be too powerful for the combined might of the other students. As John furiously expressed his anger for being used by Claire, she expressed her disgust of John becoming a tyrant and a monster. 
Claire has often appeared in a series of flashbacks in John's mind. She has yet to appear in-person in the present day.
