Fujimiya Kaori

Fujimiya Kaori is the deuteragonist of Isshuukan Friends and Yuuki Hase's classmate. At the beginning of the series, she is always alone and does not seem to have any friends. This can be attributed to her chronic memory loss, which causes her to lose all her memories of the times she was happy and of those she considers friends every Monday. Despite her efforts to resist Yuuki's advances to become her friend, she eventually warms up to him and they become close friends.
