Oblivion Island: Haruka and the Magic Mirror

Your favorite teddy bear. The model kit you spent hours putting together. The picture book you read again and again. The shiny stone you found in the park one day. Where do all these childhood treasures go when you grow up? This story follows mysterious creatures who collect these forgotten objects-things left behind when their owners outgrow them. Unseen by humans, they slip into our world from another dimension, gathering the abandoned "treasures" and taking them back to their own. There, they use these lost items to build a whimsical city known as Oblivion Island.
