In reality, the Overlord had never really died; he just stayed in a state of limbo, waiting for someone to finally teach his son the meanings of compassion, kindness, and most importantly, human/demon rights, such as the one that states they should not be used for mad science experiments without their consent.
This was so in the 'real' world, and it is so in this one. But in the real world, Mao's insecurity about his father's ghost hating him was unfounded; it was just him superimposing the worst case scenario. In this world, however, his father does hate him, and he has made everyone else in the Netherworld hate him as well.
Raspberyl, Almaz, Sapphire, Mr. Champloo, even the units he created with his own hands, all want to hunt him down. But not to kill him, oh no. They have created an impossibly-high-security prison slash mental ward, and it is here they want to lock Mao for the rest of his long, long, long life. The hope they had for him in the real world is now gone. The people who were supposed to help him regain his mind were now angry and on the hunt, ready to isolate him forever.
And isolation leads to weakness of the heart, which leads to the terribly powerful, primordially violent 'inner demon' named Dark Mao.
so basically, the "Mao destroys the world" ending? It happened.
Or at least, Mao thought he had.
