Due to Jenny, the Key Tini-ping who lived in Mystic Village came to Harmony Village. Escaping from Jenny and Dahe-ping who took over the village with the Master Key, the Royal Tini-ping (Nana-ping, Kkurae-ping, Solzzi-ping) fled across the gate and met Romi and Hachew-ping. Just then, a box of unknown identity also fell into Harmony Village. Romi is given the mission to catch all the Key Tini-ping and send them to Mystic Village.
