Fifteen years have passed since the events that weakened the Kinoko. But peace is once again under threat: a malevolent sorcerer has cast a spell on Kimino’s village, causing the elves to age at an alarming rate.

The only way to save them is to brew a Youth Elixir requiring a piece of bark from the Kinoko when it was still just a seed, an ingredient accessible only through a time portal within the temple of the mushroom god, a passage the guardian statue will open only after receiving the five legendary Roses of Youth.

This time, it is the children of our former heroes who take up the quest. Only ten years old, Niella and Cyrillus set out without realizing that little Kinie, Kimino’s mischievous daughter and the only one spared by the spell, has slipped into their bags. Together, they journey through lands filled with astonishing creatures and whimsical peoples. Kilou, back in the adventure, even regains the ability to speak thanks to an elven potion… for better or for worse.
