A golden wisp who had been living amongst humans for thousands of years, has taken many forms. A cat, a lion, a bird and human imitation has been it's most favorite of forms amongst all those he had chosen before.
But then came the new age, the 21st century were humans made a lot of new fun interesting things, he settled down as a teenager whom had gotten way too addicted in anime, mangas and Webtoons.
There was this one particular anime or more specifically one particular character which he loved the most, it was the light human admiral Kizaru of one piece.
Although never actually truly paying attention to the universe around the character and having very sparse knowledge of it, but he just loved the light Human still. He felt like him in a way although different in origin as "He" was made of the purest and most potent energy of the heavens and every second he existed was him steadily on his way to evolving into a true god amongst even other gods.
And finally, for the first time in his years of existence he the golden wisp would actually get into a conflict. The world had gotten too boring and he just wanted to start something, he wanted a taste of it, combat.
And there was no way the humans were giving him that satisfaction as he could end their existence in a blink of his eyes, he was calling them back, those god-like beings and the first generation of demigods.
And he got his wish, it finally happened. He had no idea how it happened but he opened his eyes to see he was... reborn, in a very different world but not too different. Just some very strange humans too, but one thing made him happy, this world wasn't full of just weak fleshed humans, they were strong.
He noticed he lost most of his power but it didn't bother him, he would grow into it again at some point as he was a being with endless potential to evolve, but for now he would enjoy this a bit, good and evil....never cared for it, never will.
