Kunikida is one of Kyons Friends. Kunikida is much quieter than Taniguchi with the latter doing most of the talking when the two are around. Kunikida plays a minor role and does not contribute much dialogue. However since he and Kyon went to the same junior high school he might know more about Kyon since he once stated that Kyon likes weird girls as evidence to support the idea that Kyon is romantically interested in Haruhi.
