Bonds: A Buddyfight Fanfiction

This story takes place in the world of Buddyfight. I will be making up some of my own cards for the sake of plot devices and such so if you have a question about a card I'll answer it in the comments if I haven't already done so in the chapter.
The characters in this book are:
Dorobo Kodomo is an orphan thief who steals for survival. He's a user of Magic World and his strategy involves using rapid damage on his opponent's turn and his own turn.
Hiroikku Sukuinushi is Dorobo's best friend. He doesn't approve of his friend's methods and is constantly having to step in to prevent Dorobo from getting in trouble. He plays Armordragons and his strategy involves Red Dragons.
Tsuki Raito is a shy girl who is dying from a rare disease. She plays Buddyfight to take her mind off of the pain. She is actually very athletic and and takes kendo. She plays with Katana World and really enjoys the Water Ninja deck.
Daku Soba is a mysterious figure from Dorobo's past who seeks to vanquish him for something the Dorobo did. He wields a Darkness Dragon world deck based on the Purgatory Knights. Nothing else is known about him.
