Heartbroken after overhearing Harima and Yakumo, Hanai retreats to the mountains for intense soul-searching. Upon returning, he meets Harry McKenzie—a flashy, bike-riding blonde—and ends up in an unexpected showdown. Just in time, Harima arrives for his meeting with Yakumo, and a three-way battle begins!

With only the relays left, the festival reaches its climax. Eri, injured from protecting Harima's bald secret during the cavalry battle, bravely steps up as the fourth runner. As she takes the baton, she races against pain, pressure—and possibly her feelings.
