These a knocking at the door at gohan's house so gohan decided to see who it is, when he opens the door the own thing gohan could was "dad" because goku drive straight and hugged gohan.
"hey dad how are you" says gohan nervously.
"gohan I'm sorry for everything I done to you, I left behind, I made you fight cell on your own and I let you grow up with out a dad.." says goku before being interrupted.
"no dad don't say sorry you don't need to, you want to talk" says gohan.
"yeah sure" says goku letting go of gohan.
They go outside and sit on the roof looking up at the stars.
"so what have you been doing" says gohan.
"Well I have been training Caulifla, kale, cabba and Goten for the world martial arts tournament" says goku with a smile remembering the past months.
"oh now your a teacher honestly I all ways knew you become a teacher but not this soon" says gohan laughing with goku.
"hey you know the father and son Kame Hame Ha" says goku all ready knowing the answer.
"remember? How can I forget" says gohan remembering the time he defeated cell.
"Well since the tournament has changed over the years and now they have 2v2 fights, I gonna teach them how to join they energy like the father and son Kame Hame Ha" says goku excited for the training.
"yeah the would be a great example of combining other energy" says gohan loving the idea.
"sure then it's a deal" says goku.
"deal" says gohan replying.
"hey gohan I been meaning to ask you, I get this feeling in my chest, especially when I am around Caulifla do you know what it might be" says goku who honestly doesn't know.
"uumm...i think you find out soon" says gohan knowing full well what it is.
It's the break if dawn and everyone was fast a sleep until goku decided to make the loudest sound possible shouting a energy beam into the sky.
"what old man we have 30 more seconds of sleep left" says tried Caulifla walking out of the house with everyone else
"yo I got you up early because I will show how to link your energy with another person to make you both stronger" explain goku trying to get his students excited.
"that sounds cool" Says cabba excited.
"is it like the family Kame Hame Ha dad" says Goten.
"yeah like that but first me and gohan with demonstrate the father and son Kame Hame Ha and then gohan, Goten and me will demonstrate the family Kame Hame Ha, you ready gohan" says goku ready for action.
"yeah let's do this" says gohan getting pump up.
In perfect synchronisation they both says "KAME" gohan gets his right arm ready and goku gets his hands ready, "HAME" and a blue ball of energy appears in gohan's hand and in between goku's hands "HA" they out sketch their arms combining their energy, almost triple the size of the super Kame Hame Ha, the energy beam shot through two mountains before disappear out of sight.
"now for the family Kame Hame Ha, come Goten" says goku excitedly.
"okay" Goten says joining goku and gohan.
Again in perfect synchronisation they shouts "Kame" all of them in sync with each other putting there hands together, "HAME" three blue balls of energy appearing in their hands, "HAAAA" out sketching their arms sending the energy beam through multiple mountains and trees not even slowing the beam down.
"and that's how to join your energy with one or more people, okay Caulifla and Goten go together since your the strongest in the group and Kale and cabba you two go together have fun" says goku watching over the young saiyans with gohan.
"okay big sis caul let's do the brother and sister Kame Hame Ha" Goten says more excited.
"okay but don't called me caul" shouts Caulifla.
"hey you okay to do this kale" says cabba worried about her shyness.
"y-yes I'm okay" says kale shyly as she walks over to cabba but slips and falls into cabba's arm and they spent 5 minutes blushing at each other.
"well okay I will do my galick gun and you do a Kame Hame Ha" says cabba being the first to come to his senses.
"o-okay" says kale shyly again, getting in the proper position.
In sync with each they says "Ga" and "Kame" with their hands in position, "lick and "Hame" with energy balls appearing in their hands, "ha" and "gun" energy beams merging together shot towards a tree and then there was no tree.
Several hours later.
"perfect you guys have mastered combining energy's together" says goku proud of his students "okay have a good night" says goku as the tried saiyan's walk past.
"hey old man I want to ask you something" says Caulifla starting to blush.
"yeah sure" goku replying to her question "by the way your face is turning red" goku points out the obvious.
"shut up old man" shouts Caulifla as they walk off.
"hey kale Caulifla is beginning to talk to goku a lot" says cabba wondering.
"y-yeah yesterday she said she f-feels something when she is with him" says kale.
"do you mean" says cabba shocked.
"y-yeah she's in love with him" says kale confirming cabba suspension.
So training has carried on normally until three days before the world martial arts tournament, the things that changed are their power levels and kale is less shy now.
"because the tournament is just three days away I want you to fight me" goku says getting excited.
"wait what" says everybody confessed about goku's idea.
