Chapter 1: Inheritance

Kaito stood on the roof of the Heartland Tower, watching the crowd below going on with their lives. He was dressed completely in black, with a hood covering his face. Looking at them, he smiled and thought, I was like them, going on with the daily things and never considering it was living. How things have changed.

Three figures approached him from behind, but he sensed them and turned around to confront them. "Is there something you guys want?"

The leader of the group stepped forward; he said, "We came here to return something to you, Kaito Tenjo, no, sorry, Kai Atlas."

"It seems team Ragnarok has not aged in over twenty years, Harald."

"The Gods are responsible for that, though I am glad that you remember. We became aware of your presence and decided it was the right time to return what was rightfully yours."

Kaito, Kai, looked at his long coat. It was supposed to mask his presence when he returned. Did it not work? "How did you become aware of when I returned?"

"Our Nordic Gods foretold us of your arrival through our Rune Eyes." Suddenly all of their eyes began to glow, a symbol appeared on each of them. "Now, will you accept your inheritance?"

"My inheritance?" Inwardly, Kai felt relief; his presence still remained hidden from the Barians, or so he hoped.

"Your father's deck. Before he… disappeared, it was entrusted to us. He instructed us to give it to you when you completely understand your role. Now that you are ready, it is yours." Harald handed him a small jewelry box.

Kai opened the box and found a container filled with cards and a blank card next to it. Sensing what Kai was about to ask, Harald explained, "That blank card used to be your father's most powerful monster, but it and all other Synchros vanished the day he disappeared."

The moment Kai's hand made contact with the card, it glowed and Red Demon's Dragon appeared on it. Brave, Dragan, and Harald could not hide their surprise as they whispered, "That's impossible. It can't be."

Holding his hand open towards them, he said, "May I see your Synchro monsters? If I have the ability to restore this card, there might be a chance I could restore your's. Anyway, I want to repay you giving me this. Even though you were just following instruction, I still feel indebted to you."

As he passed his hand over each of the card, he noticed a portion of his energy dropped each time he restored a card. When he was done, Dragan said, "Even though your father was proud and arrogant, he was a great duelist, and above all, a good person. He would have been proud to call you his son."

Suppressing a smile, Kai replied, "It goes both ways. I am proud to call him father."

Brave walked up and said, "Don't forget about me. I'm always here to help."

"… Thanks. Before you guys leave, can you promise not to reveal my presence yet? It would cause a lot more problems."

Harald nodded, "We understand. Sometime, secrecy is the best way to win a duel."

They turned around and walked away, leaving Kai to stare at the deck he held in his hands.

Thinking to himself, he realized, This power might have been what the Barians were after, but either it proved unreliable or dangerous for them to use. He placed his father's deck onto his belt, next to his own. This is mine now. I have to stop thinking of it as father's. He entrusted it to me. Since he died to protect my future, it's my job to continue his legacy. I have to do what I think is right. With that in mind, he ran towards the Dimensional Transporter he helped build.
