In a world where two worlds exist...The Original Realm and The Boundless Realm. The original Realm is where all the planets of the solar system reside. The Boundless Realm is made up of 38 planets of the Infinite system. And in all of these planets, aliens of many different kinds live, work and survive. The Boundless Realm is held together by an unknown sentient source of energy in space called Boundless. The Boundless Realm and Boundless don't real have a known cause for their existence, they seemed to have spawned out of nowhere.
But the earliest recording of it is in 1902 when an old man who was a time traveler discovered a blue, glowing key in his attic. He didn't know how it got there, so he grabbed it to take a closer look at it. But suddenly, the key started to glow brighter and before he knew it, he was in a different world. His 20 year-old nephew happened to witness this and as result he ended up burning the key. No one knows what happened to that man.
How one gets into Boundless is to get a "key of infinity" which is a blue, glowing, magical key that has an infinite loop symbol in the middle of the top part of the key. By grabbing one of these keys, you will be directly transported to The Boundless Realm. How do you get out? By attempting to get one of the keys from Boundless. Which is easier said than done, since Boundless is extremely powerful.
And that leads us to today. A 16 year-old Filipino boy named Dom decides to run away from home, due to his rather troubled life. He ends up lost in the forest and stumbles upon an old shed, goes inside, and finds a glowing key and grabs it. And that's where it all began...
