In order to return the light to the magic tree, Ori must recover 3 elements located in 3 separate areas and the story of Ori and the Blind Forest ends sadly.
On the journey to recover the water elemental at Ginso Tree, Ori and Sein encountered a creature called Gumo. Gumo can be considered as the last creature of the Gumon race, a race that protects the element of the wind. When darkness enveloped the Nibel forest, instead of opposing it in order to gain light, Gumo gradually decayed and accepted darkness as part of life. Gumo stole the Water Vein, which needed to get into the Ginso Tree, from Ori’s hands.
From then on, Ori constantly had to play hide and seek with Gumo as the creature repeatedly ran and mocked his master. Gumo gradually lured Ori to his hideout, where it had an advantage. Continuously are the traps that Gumo created to get in the way of Ori. Then ironically, when Gumo was trying to create a hail of ice down Ori’s head, it was trapped by a giant stone pinned to its feet. Although Gumo caused many difficulties for her, Ori decided to save Gumo from being trapped. This awakened Gumo and changed his mind, returning Water Vein to Ori to continue the journey to restore the light.
After restoring the elemental element of water, Ori and Sein had just left the Ginso Tree when they suddenly encountered Kuro. With his tremendous power, Kuro made everything shake, causing Ori to fly to the ground below. While Ori was falling in the air, Kuro was about to finish off this small creature when suddenly, Ori was saved by Gumo as a way of expressing gratitude, so that Ori could see the water element restored.
Ori and Sein continue their journey to the Misty Woods in order to unlock Forlorn Ruins, Gumo also follows them both. After finding the Gumon Seal, they enter the hidden area, where Gumon used to work and witness the scene. statues of Gumon that have been frozen to death. Gumo felt pity to realize that she was indeed the last Gumon, and from here Gumo understood her responsibility to restore all the light elements with Ori to save Nibel forest. After Ori and Sein recover the element of wind. Gumo overheard Ori’s intention to restore the Gumons’ ruins in their honor. Deeply impressed by Ori’s heart, Gumo decided to bring Light Vessel to the place where Ori and her mother used to live.
After recovering the element of wind, Ori and Sein left the hidden area, both discovering Kuro’s nest and understanding the truth of the matter. As the mother of 4 children, when the light ceremony to call Ori back of the Spirit Tree took place, its light flooded into Kuro’s nest and Kuro lost 3 children. In rage, Kuro vowed to protect the son of his same and revenge. Kuro eventually attacked the Spirit Tree, robbed Sein and hunted down the Guardian Spirits including Ori in the belief that these creatures would restore the Spirit Tree’s light and harm their last child. Kuro suddenly appeared, forcing Ori to flee its nest.
With only the element of warmth remaining, Ori and Sein set out for the Sorrow Pass to reach Mount Horu. While Ori was searching for Sunstone to make her way into the mountains, Gumo arrived at the place where Ori and her mother used to live and found Naru’s body. Grateful for what Ori did for himself and his fellow Gumon, with Light Vessel in Gumo’s hands reviving Naru. Together, Gumo and Naru set out to search for Ori. From here Gumo realized that Ori’s place would be her new home. On the way to the mountain range where Ori was trying to recover the remaining element, the forest was engulfed in flames. The debris burst from the volcano caused Gumo and Naru to be divided and had to choose their own path.
Meanwhile, Ori and Sein increasingly moved deeper into the mountains. With her skill and courage, Ori overcame many challenges that the mountains posed and finally restored the element of warmth. But before celebrating, Kuro flew to Mount Horu. In his last efforts Kuro attempted to chase Ori in flames to prevent Ori from reaching the Spirit Tree.
When Ori was near the Spirit Tree, Kuro appeared to make Ori unconscious. At that moment, Naru in the flames ran to hug Ori to protect his child. It made Kuro realize that his actions were making him something he hated like the Spirit Tree, killing other people’s children. Understanding his long-standing mistake, Kuro accepted his sacrifice rather than continuing to spread the darkness of the forest. Kuro then brought Sein back to the Spirit Tree. The light from the Spirit Tree filled the forest, but also killed Kuro.
The light from the Spirit brings back the inherent life of the Nibel forest. Naru and Gumo return to the cave where Gumo received the new home with Kuro’s last egg. Ori returns to the Spirit Tree and witnesses the other Spirit Guardians being born.
