She was a good-for-nothing everyone bullied. Her cousin drained every drop of blood from her body, stole her bonded spirit beast, and threw her into Dark Demon Ridge to fend for herself.
Returning from the Demon Realm, she makes a powerful comeback, seizes spirit beasts, kills her cousin, and reclaims her position as Imperial Princess.
With the Realm Core in hand, realm beasts at her side, and cute pets all around her, she is unstoppable.
From then on, Dark Demon Ridge acknowledges her as its master, the Beast Soul Abyss becomes her back garden, and the Ten Thousand Demon Grottoes cower beneath her feet.
The geniuses of the Spirit Realm, Immortal Realm, and even the Divine Realm are dazzled by her mastery of spirit-beast taming and can't help but sincerely worship her: "Her Majesty the Empress is unbelievably cool!"
