On one fine morning, after waking up from bed and stepping outside, Pon finds a newspaper on the ground and reads to find out that Otane-chan, Pon's favourite music idol, had been kidnapped by Tengu of the Forest. With the help of the Del Montas brothers, Pon enters Tengu's cave finding Otane-chan trapped in a locked door, before Tengu descends down to meet Pon. Pon pleads with Tengu to change his ways and release Otane-chan in exchange to become Pon's friend, however Tengu refuses, claiming that as long as he have Otane-chan, he don't need anymore friends. As Pon rants at Tengu, Tengu then tells Pon that the door can only be opened with 7 keys, which were hidden around the world, before ascending and disappearing. Pon decides to set on a journey to recruit his fellow friends, find the 7 hidden keys, and save Otane-chan from her imprisonment.
