I do not own kingdom hearts or Chrono Cross and this is just for fun .

Chapter 1

Sora took a breath after the gummi ship crashed in a fortress and saw a weird flame . He hard Donald and goofy screaming at him and noticed a party of three entered the room . He looked at kid and was shocked " Sister I thought you died " he said as kid punched and put her dagger at his throat . He chuckled and flipped her with one hand and stole her dagger . " been a while teach even thou we are not really related we're still family even thou you left destiny island " he said . He blushed as she kissed his cheek and then flipped him over taken back the dagger . He summoned his key blade as heartless appeared and nodded as did Kid . He took out more heartless " I win teach " he said stopping serge from killing kid and looked at lynx body . He took kid hand and fled leaving Donald and goofy behind .

Kid smiled and ruffled sora hair " you have grown up Sora " She said and took a breath . " help me get the frozen flame " She asked . She noticed Sora nodded sure and rolled her eyes . " you still have a crush on me " She asked as Sora looked away . She took his hand " anyway let's get away from this fortress partner " She said as Sora turned red and was silent as they reached a town and bumped into van . Both entered his mansion and relaxed . " thanks van " she said as his butler brought them some food . She chuckled as Sora ate it all " so let's see what each other is up to before deciding what to do next " she said .

Sora nodded with his mouth full of food and chuckled as he swallowed the food " Well I can't really talk about it because of the world order just like when I was five you trained me as a thief kid " He said . He chuckled tossing her dagger back to her . " to whatever happens anyway let's find lynx because I think the one who tried to stab you was lynx In Serge's body " He said as Kid sighed and took a breath before going to take a bath . He saw van was listening and took a seat . " I get it kid doesn't want to believe serge is in lynx body while lynx is in Serge's body " he said as Van nodded

Kid relaxed in the bath and looked at the ceiling . She closed her eyes and chuckled " Sora saving me , never expected that and he's right we should ask lynx to see if he is now serge " She thought . She took a breath and sighed seeing harle break in throu the window . " I have a question for you Harle is serge in lynx's body " She asked as Harle decided to join her in the bath . She sighed again " I know we were enemies but let's do our best together if serge is in lynx's body " she said

Harle washed kid's back and sighed seeing van and sora peeking throu the door as the two girls bathed . " yes serge is now master lynx " she said . She sighed herself " about the weird creatures stealing hearts do you know what they are " she said as sora and van fell inside the bathroom . She noticed kid pointed to Sora and both girls undressed van and sora and tossed thier clothes out the window . " now then Sora please give us some information " she asked .

Sora scratched his face and joined them in the bath as did van . " well Harle I kinda met you already after kid in my childhood you washed ashore on destiny Island in your dragon form and I kinda used the skills kid taught me to save your life by stealing medicine " he said . He noticed kid had a few questions as she washed his back . " oh Harle explained it involved time travel and she wound up on destiny Island " She said .

Harle chuckled and smiled " interesting Sora I haven't met you yet but you met me " She said as they finished bathing . She looked to kid " could it be the frozen flame caused that " She asked as Kid shrugged her shoulders . She chuckled and got redressed along with kid and left Sora and van with no clothes . " I have to return to master lynx will be waiting for you kid , Sora , and van " she said leaving as both boys came out in towels .

Kid crossed her arms and looked to Sora and van . " let's get some sleep van and Sora " She said heading to a guest room . She entered the room and laid down on the big bed . She took a breath " the last time I saw Sora he was a little kid and now he is my age , I wonder how riku and Kari are doing " She thought remembering how both hated when Sora learned the skills of a thief from her " as she fell asleep and chuckled as a knock was on her room door . " come in " she said .

End of chapter thanks for reading , I know a weird crossover of kingdom hearts and Chrono Cross . I just thought it would work and I think it does . So let me explain Sora met kid while as child and same with Harle but Harle was from the future after meeting the older Sora basically wanted to include time travel and I plan to rewrite it to start from that point so this is a one shot for now till I rewrite it or will leave this and have it be a dream the young Sora has before meeting kid
