25 years ago:
at the time king cold still had Control over the saiyans deep within an overgrown forest inside an massive palace on top of an golden tree sat the supreme goddess of time shuna she was betrothed to the true primordial demon god bazelander and they ended up having 4 sons that became the primal demon gods under the command of their father
while their mother grew bored of their father and decided to look for more intimate relationship as she was forced to marry bazelander by Zeno-sama so bazelander wouldn't hard to take over the multiverse and become the King of everything it worked and shuna was forever loyal to Zeno but she never loved bazelander and the only reason she ever tolerated him was because of her sons.
As they respected their father and she was afraid that he would take her sons away from her as those children were born into the worse situation imaginable shuna made up her mind to find a more intimate relationship one that she would actually love the first planet she visited planet Vegeta using God magic she transformed herself into an Saiyan as she Wondered the streets she saw her future lover durai an 25 year old Saiyan using her God magic to see his soul he was completely pure hearted unlike others on the planet.
By the bruises and scratches he was either beating up or came back from an mission either or shuna approached him as they chatted with each other and eventually became a thing shuna would sneak away from her arranged husband to see her true lover after a couple of months of dating she revealed her true form as the supreme time goddess shuna though he would be disgusted or be angry that she had lied to him but he hugged her.
And that hug turned into a kiss and couple hours later durai was bitten up chained down and made an good boy and from that amazing night in bed came triplets of an god and an Saiyan fearing for the life of her lover and her children who she arguably loved more than her original children she transported them to a distant planet and used her god magic to cover it in a protective veil that would protect them for a couple of years in the time frame of her still seeing durai he had explained everything and trained him as fast as she could in the end somehow bazelander found out about shuna male concubine.
And tried his hardest to find him and eliminate him but he couldn't shuna had killed bazelander out of her domain sending him back to the demon realm of course they were still married but now bazelander started to resume his plans of slowly but surely conquering the multiverse multiple planets had fallen under his Pantheon each day his power grew stronger and stronger.
Those half blood children would rise to do great things when they.
