Ok, here is a rundown. You came to the blakeory library in scholar district with melia and erin, but get kicked out thanks to huey punching thomas blakeory. you run into reina and the story diverges a bit where kanon showed up and invited you to the badlands or reina gets caught by bladestar, then you are in a cave and run into ren, you head to sashila village and you are assigned to defeat the Dimensional rift but are transported in the past by a guy hovering on a skateboard. you follow the plot and you end up fighting a dark gardevoir who is a dimensional rift then you go back then participate in the tournament and beat adam might. to start the new chapter you re-enter the left side doors
