As for Sister Sasha, his attitude was almost one of disregard, as if the emperor's illegitimate child were desperately trying to deny his humble lineage. It is said he even views her as his disgrace, though there isn't any evidence—because of Sister Sasha's existence, he possesses a trace of mortal characteristics.
You can tell his inclination from the fact that he named the race he created "Son of the Moon."
Because of this, he was obviously dissatisfied—even angered—that he hadn't become a "Perfect Being." After leaving words for his descendants to develop in that direction, he directly entered the Dream Realm with his physical body.
Until today, the Sons of the Moon have not produced a genuine Perfect Being.
And the Blood Celestial Marshal believes that humans and Sons of the Moon indulge in pleasures because of the primal beast desires deep within them.
