Mikey loses Mitsuki's ticket to the bullet train ride to a fan club dedication ceremony in Nagano. The gang has to leave her in Tokyo, while the rest of them board the train. Bored, Mikey explores the train only to find Mitsuki tied up. Someone knocks Mikey out and the next time we see him, he is back in his train car.

When they get to Mount LilyMu, Mitsuki is in danger of a falling avalanche, which Mikey saves her from, and Mount LilyMu is left in half of what it was. In the subplot, Yesman quits after a bad day of service to Ozu.
