Yugioh 5D's: The 5th Signer (My Version)

Ok, so anybody who watches 5Ds knows that Roman Goodwin was the 5th Signer, then it got passed on to Crow Hogan. What if a certain guy known throughout the Multiverse (That was born in this Universe) got it instead when Yusei had his unofficial Turbo Duel with Jack? Find out now.

It was a calm, cool night in New Domino City for Sean Babin. He didn't have a care in the world, not one. He was on his way home from getting some new cards while passing by the Kaiba Dome. When he heard the sound of 2 monsters attacking each other in a Duel, he felt his arm burn. Sean lifted up his sleeve to see why, then a glowing red mark started to appear on his right arm in the shape of a Dragon Head. There was a bright light and then it died out, leaving the mark on his arm. Sean pulled his sleeve down and started running home as Sector Security came closer to the arena.

(Next Day) "Okay, so I got Dark Magician Girl, Magic Formula, Sage's Stone, Dedication to Light and Darkness, and Dark Magician of Chaos.  These are some good cards." Sean said to himself as he opened up his new card pack.
