Prologue
In an alternate dimension, humans and Bakugan lived peacefully on the same planet, New Vestroia. As long as humans didn't bother Bakugan, Bakugan didn't bother humans. Bakugan lived in the wild, humans lived in civilization. Small cities and towns of humans were scattered all over the world. Some humans even resided in Attribute Realms, realms with hidden entrances around the planet where Bakugan with attribute heritage could enter while regular animals and humans could enter on their own. Most Bakugan didn't get involved with humans and the few that did helped their lives along, be it help building structures or defending them from opposing people and Bakugan alike. Though humans wanted to defend themselves against Bakugan, they knew that Bakugan would always be stronger than them. They also knew that Bakugan were a lot like them as well. While humans raised their young in a more controlled environment, Bakugan raised theirs in a more natural one. Humans needed water and food as necessities to survival and some Bakugan needed it as well. When one was in pain, another helped them no matter if they were humans helping Bakugan or Bakugan helping humans. They were more alike than a lot realized. A few things hadn't happened in Vestroia history but something that never happened before finally did… human children raised by Bakugan. Yes there were human children that were raised by wild animals, a few in recorded history, but never had the two intelligent creatures interacted in such a way until six children and Bakugan made history.
A young boy, filled with an energetic fire, found care under a Bakugan that never thought he would be in such a position.
A little girl that was jealous and longing for attention got hers from one of the most understanding Bakugan of her time.
An obedient son broke from doing as his parents ask to learn more about Bakugan and found a friend in a Bakugan which would make him laugh.
An adventurous daughter got into trouble, causing her to forget her past, and was found by a loyal Bakugan that promised to protect her.
A child that lost someone important to him, would be taken under the wing of a Bakugan that would help him become closer to the wind that his someone important encouraged him to love.
A child with a strange fondness for darkness lost all of her family gained a companion in a not-so-merciless Bakugan.
These six children formed bonds with Bakugan that no human ever did before.
