The objective of this report is to investigate the pluralism and the compatibility among polyamorists, focusing on the gathering of a polyamory group in California and polyamory terms that are used by polyamorists. Polyamory means "responsible non-monogamy". It is best explained with the words: "honesty" , "consensus" and "responsibility". In fact, most studies about polyamory have pointed out that people who are recognized as polyamorist have various backgrounds, and the ways of practicing polyamory are extremely diverse and inconsistent. In this article, I look at polyamory in terms of a "contact zone" where people who have various thoughts and cultural backgrounds are interacting. I examine how polyamorists connect with each other in their contact zone. In order to achieve this purpose, "Cyborg Feminism" which is advocated by Donna Haraway is a key concept. Donna Haraway seeks a way of connecting that is not emphasized by homogeneity in "Cyborg Feminism". Cyborg is a body which holds multiple internal differences. Primarily, looking at the meeting of a polyamory group through the image of a cyborg suggests that polyamory has plural and comprehensive characteristics. Secondly, I examine the polyamory terms. The terms in polyamory are not only a tool of communication, but also a tool of self-accountability, one's relationship and the love they belong to. It implies that the ethical question of "How should I treat myself?" is shared among polyamorists. Polyamory is composed of multiple perspectives, and it is not a group which has only a single value system. There are blank spaces following the question "who are we?". However, the otherness and the blank space which polyamory holds are the possibility of critical self-forming with others.
