Hello Kitty no Yuki no Joou

Gerda and Kai are inseparable friends until the Snow Queen appears and freezes Kai's heart, carrying him away to her distant palace. Refusing to abandon him, Gerda leaves home and journeys north through unfamiliar lands, meeting people and creatures who help or hinder her search.

Beyond the cold and danger lies a friend who no longer remembers the warmth they shared. Gerda must reach Kai and break the Snow Queen's hold before the ice around his heart becomes permanent.
