Himeko's friend and roommate, "Mako-chan" is an athletic girl, one of the best runners on the Ototachibana track team. On the day S�ma attacked Himeko, she was severely injured in the collapsing dormitory. Her competing in the Interhigh competitions was shot to pieces. She pushed Himeko away, possibly blaming her for the injuries, but more likely distraught over not being able to run anymore. She no longer appears in the series until near the climax, where she helps Himeko to come to a final decision regarding the events surrounding her. (from wikipedia)
