'Adam'!
The first human created by God in the Bible of the previous life.
He was naturally the epitome of 'perfection' as a complete human being.
As the name suggests, the Fifth Essence of the Creator's Path, the "Perfect Man," represents the most perfect human form.
Or, one might say... the form after the "Human Completion"!
As for the process of 'Completion,' it is, of course, the 'Melting Furnace' gradually becoming more 'perfect' by consuming various spiritualities.
However, the 'perfection' in Mystery may be slightly different from the 'perfection' defined in the secular world.
"The legacy of the Sixth Element 'Under the Crown'..."
"It's tough to kill a 'Under the Crown'... the reason why I judged the 'God of Suffering' this time is that I took advantage of his promotion ceremony's vulnerability... if he hadn't entered the ceremony, I wouldn't have been able to defeat him back then."
