Resolution

  Show spoilers »

The culprit is Yukiko Mori. First, she knew Kiyomi was leaving first, saw her off at the station, and established what time she boarded the train. She timed how long it would take for the body to loop back around to the station and return. The murder weapon is the headphones. When they boarded the train, Yukiko took too long to retrieve the headphones and yanked them so hard that they snapped. When Yukiko opens the CD player, she finds a thankful message wrritten by Kiyomi on the CD. She breaks down, confesses and reveals that she became enraged after Kiyomi stole her boyfriend.
