Renamon wa Tomodachi! Ruki no Mayoi

Rika is being followed by a mysterious icy force, which frightens her. Not wanting to admit it, she refuses help when Renamon offers to protect her. Renamon is dismissed, and feels hurt by what Rika said to her. While Rika is vulnerable without Renamon's protection, IceDevimon then appears and captures the girl, taking her into an alternate dimension, an icy tomb where he has sealed his Digimon victims.
