Sharing my story idea

There’s this demon like character that lives in similarly unknown island. They have parents and a younger siblings that they love so much. Crazy stuff happens and they are transported out of the island to a continent. They’re going on a journey to go back home. But there’s other demon like characters that are evil like enemies in a video game. They finds out that they have a special power. When they create a strong bond of friendship with an individual they can transform. Like an engineer/scientist have a good bond with them, they would look like a robot type being with lasers and hacking. If they make a bond with a dynamic energy and passion with a fire like personality, they would have a fire form. Some would go along with them in the journey home and most would stay in their areas but the bond is still there and she can still have that transformation.

Haven’t decided on the gender of characters and there some background lore in the world
