What is the author's style in Monologue for an Onion by Sue Kwock Kim?

Kim interjects irony in Monologue for an Onion to illustrate the human being's struggle with truth. She also uses metaphor, with the onion representing anything that is pursued and destroyed as a means to an unattainable end. Personification is utilized to give a humble onion a voice with which it can verbally fight back against its attacker. She chooses to use the form of a monologue to reveal the onion's thoughts and feelings about its situation and the person peeling and cutting it.
