Despite descending into chaos due to the unexpected appearance of the Wicked Witch of the Tower, the emergency summit at the Principality of the Nine was a success in one crucial respect: The former Princess Lilith was now Queen Lilith of the Human Kingdom. But despite everything being done by the book, the change of monarch has deeply angered the Demonkin Nation, especially as it quickly became apparent that an affiliation with the Wicked Witch and the nations she had brought to heel was how Lilith secured enough votes to get what she wanted. Threats of harsh reprisals against the Human Kingdom soon follow, and with her back against the wall, Lilith turns to Light and his allies to save her nation from this new threat. Meanwhile, he sees this as the perfect opportunity to ratchet up his campaign against his sworn enemy, Diablo, who retaliates by enlisting the services of the Bourreaux, the world's deadliest gang of assassins, led by the deeply deranged Master Gira!
