Okay so about a hundred digi-years pass for each earth year so it's been 400 years for digimon history(which means the first digidestined have come and gone) while Gennai has had Tai and his three digimon in a cryostasis called digi-stasis were he aged on earth time that is 4 years. Now on with the story Huzzah
Present day Highton view terraces Tokyo
Hikari Kamiya or Kari to her few friends was sent to summer camp after her friend Mimi insisted she come with and arguing with Mrs. Kamiya over her daughters safety finally getting her to cave in with the tailored classic "Don't you want Kari to make friends with people outside of study buddies and T.K?" so here she was sleeping in a tree when suddenly snow woke her up as it started to snow till the sky was hidden behind white icy winds mean while in the great big digital toolshed...
Tai awoke near the Tokyo port deposit point he was now eleven years of age and knew how to fight hand to hand better than most people twice his age with military training. He wore black combat boots and black cameo shorts with a tan shirt and a black choker with two red eyes shaped jewels set in it that blended into his background no matter where he was. Suddenly the telltale noise of a group being transported sounded so he slipped in to a tree jumping 5 feet off the ground to observe who was going to be the digi-destined. He saw a girl with brown hair so much like his own when he first arrived he realized Kari was now here he promised himself to protect them as he knew very well throughout her adventures as he knew she'd be under attack from the very start so he snuck off knowing they'd end up at Free-fall Cliff(the cliff at the end of the first episode) with their digimon partners. The telltale buzz of Kuwagamon suddenly filled the air "Hmm well let's see how well they do against Kuwagamon my friends" he commented to the three digimon who had taught him as best they could to survive in a world he was unprepared for. anyway he noticed Kairi was cornered on Free-fall Cliff "why is she alone?! a mistake like that could cost her life" Tai jumped down in front of her and puling out a pen and ink he wrote Digicode for fire shooting a fireball at Kuwagamon scaring him off
"hey are you okay..." He stiffened and said "I have to go" before running off leaving behind one very confused Kairi Kamiya
And CUT! well that's all and I see Digicode as being a way to affect the data around you almost like Runes In Harry Potter(a missed opportunity for awesome magic IMO)
