(Fifteen years ago.)
Lord Hasegawa watched in awe as the man dressed in the green karate Gi and black kung fu pants over took his dragon troops using nothing but mere strength alone he then turned to the dragon emperor, Hasegawa Yamamoto the man was surprised when the other old man smirked he then dashed with the force of a sonic boom coming at the dragon king with a right roundhouse punch and then another fallowed by a swift spin kick ,a double snap kick and a slashing roundhouse kick.
The moves shook the very fiber of the dragon emperor's body, the dragon emperor attacked the man with a powerful step in elbow, fallowed by a spinning kick, then a double palm fallowed by rising sun fist.
Finally he preformed his patented roaring dragon bite strike the swiping double fist blasted the man with the aura of a dragon.
But the man then preformed a drilling punch to the dragon emperor's body causing him to vomit the blow had the hidden aura of a god.
Later to make peace with the dragon emperor, the man promised his own child to lord Hasegawa as an heir but then they appeared the Nagaya emperor and his Nagaya sovereignty.
After that the Humans elves kitsune and even dragons turned to that man as there leader his answer giant robots called guardians mythical being's from ancient times brought to life by the use of modern science and ancient sorcery.

"Now that our children are old enough it's time for them to marry his son has grown to be a fine warrior but has come to hate his old man, but didn't we all at that age plus he's being put in a situation against his will." Said the dragon emperor Hasegawa Yamamoto.
"You promise me you will be good to this human boy and not be too rough on him" said Hasegawa.
"Yes Ota-Sama" said Mitsuki Yamamoto the beautiful dragon princess said with a smile.
She knew all to well what her father meant it was no secret that she was Kentaro Matsumoto's childhood bully, she teased him and picked on him whenever she got the chance but it wasn't because she didn't like him or because she hated him it was in fact the opposite, she loved him and she wanted him to notice her so she secretly teased him trying to awaken the power sleeping within him she knew he had it if he could control Daishin-oh!.
Then last semester he had revealed his true strength using the tornado flame knuckle of the martial art Mitsuki was in awe at the beautiful flaming spiral.
she arrived at the building and went up the elevator.
bracing herself for what is to become the most challenging moment of her life.
"ah Kentaro Sama I am here to be your loving bride!" said Mitsuki Yamamoto.
she noticed Kentaro wasn't the only person there.
that elvish half-bred was here too Lauralie hausenfuast.
"well I'm out of here catch you later Kentaro!" said Lauralie.
and she ran out the door.
"listen ken-Chan I'm sorry about this if i had known we were to be married I would have treated you better."
"well what's done is done as the old saying goes, come on in I'll fix you a yakisoba bun."
after the delicious fried noodle hotdog was handed to her Mitsuki Eye'd the mysterious human food, she had always eaten stuff like prime rib and Fala Menyon, but she had never once eaten the starchy goodness of a piece of bread stuffed with tangy fried noodles.
"it's not going to kill you!" he joked.
she took a bit and she smiled
"Oishi-it's delicious!"
in the secret room of the hotel the two fathers are laughing at the cute scene.
"they say that the way to a man's heart is through it's stomach and of course that goes for dragon's too I never will forget how I proposed to my Saki-Chan with a feast of her favorite pulled pork ramen."
"so it's agreed that he will become a member of the guardian force!" asked the lord Hasegawa.
"yes he can't stay cooped up here forever!' said keiji taking a sip of his tea.
