Heya took the Life, Fruit of Knowledge, completing the Angelic Hierarchy promotion ahead of Milia.
Milia still has to undergo the process of transforming from ancient angelic appearance to human, which Heya does not need, hence her speed is much faster.
Heya acquired the Golden Rule at the level of the Seven Virtues, four wings at the level of the Cherub, and automatically exited Hexuno's Angel Legion due to this promotion, resulting in changes to the Cross Stigma on her chest.
Originally, the Stigma was the uniform Cross Scale Sword of Hexuno's Angel Legion, now it is a slender golden sword with four wings, relocated to the left chest position.
Wayne saw clearly that there was a mole under Heya's left chest, not even as big as a sesame seed, it wouldn't be mistaken.
After completing the promotion, Heya folded her wings and came to the center of the Holy Temple, kneeling on one knee in homage to the Lord Son of the Holy.
