Natsumi's Friends both have short dark black/ brown hair. The one that was most likely the inspiration for Yayoi has shoulder length while the other one has short, shaggy hair held by two clips. They wear the common Kissho Academy uniforms in the manga, which consist of beige short sleeve sweaters, with white long sleeved undershirts and plaid skirts as well as baggy white/black socks and brown slip ons.
Natsumi's Friends appear in the 1st chapter of the manga. They walk with Natsumi after school and talk about alien invasions.
