Main Story
Hilda, her mum, Twig and Alfur are enjoying a picnic out from Trolberg. At one point, Hilda hears a mysterious voice. The voice was revealed to be a fairy named Flora. She tells Hilda that the fairies reside in a forest that the citizens of Trolberg has not yet visited. Meanwhile, a businessman is overlooking a construction for a new shopping center for Trolberg. Unbeknownst to him is that deep within the construction site is a prison that holds off an evil serpent named Orochi. During construction, Orochi is released from his prison and is bent on destroying all of Trolberg and make the citizens his slaves to build a new city solely for him. Orochi also summons his army of minions to assist in his tyrannical conquest.

Seeing this, Flora enlists the help of Hilda to collect a set of artifacts known as the Three Sacred Relics, which consist of a jewel, a mirror, and a sword, to awake Amaterasu, a goddess that sealed Orochi in the past, in order to put him back into his prison. Flora tells Hilda that Amaterasu's shrine is in a place north of Trolberg known as the "Forgotten Valley", a place once occupied by people in the past but was abandoned after some time. Accepting Flora's wish, Hilda goes on a quest to retrieve the Three Relics, then go to the Forgotten Valley so she can awake Amaterasu from her slumber and save Trolberg before Orochi destroys it once more.

Hilda and the Mysterious Island
Hilda, David and Frida are stranded in an island far from Trolberg when a storm broke out, while they were trying to complete a Sparrow Scout badge. The trio, with the help of Twig, Alfur and Flora, must escape the island and make it back to Trolberg while avoiding dangers that inhabit the island.

Hilda and the Stone of Light
After discovering the existence of the stone of light, the Marra, who once tormented david in his nightmares, thought of a very evil plan that would cause eternal harm to the people. Along with the rest of her kind, Kelly and the others would somehow manage to destroy the stone and scatter the pieces throughout various parts of Trolberg and the forest, causing the people of Trolberg to slowly fall into a deep and eternal sleep that would leave them having nightmares forever. One of the unlucky ones were Hilda and her two friends Frida and David. Luckily, Flora managed to resist the eternal sleep and managed to wake up her three friends who helped them to seal Orochi previously, and now they would embark on an adventure to restore the stone of light and stop the Marra.
