Walking what left on Remnant

A Prodigy teeneger who suffered from depression is transported in the world of Remnant. A world where Huntsman other wise known as Child soldiers is a prestigious job with high mortality rate with an enemy that have a Global population of 95% Grim over 5% human ( not including animals etc ) A world where a lot of twist. A wizard who have problems with his wife and care not for human lives. masquerading as a saviour of humanity even if he 100 percent knows that his enemy is immortal. and. An Immortal Witch that has power over ancient magic that can brought kingdoms in her knees and control over the monstrosities known as grim. that has immense hatred towards the Gods along with her Traitorous and child killer of a husband. Ex-Husband. And Main characters and citizens that is easily manipulated by the world's society. or at least what Roman understand. ( Our Mc. not Torchwick though. ) How can he survive the new world? Simple. He has his own version of Immortality ( Cellular level Regeneration. ) and Power to connect through his game account called Mutants genetic gladiators and transport his mutants in Remnant. And Roman care not of the other people as long as they don't benefit him. What will happen to the world of Remnant. if they encountered a Wise yet 'evil' apathetic teenager that has control over the Mutants. They viewed him Evil. Yet he called it being smart. they mocked him and insult him regardless off his history. He just laugh and ignore them as they're home is being raided by grims and bandits. Ozma tries to manipulate him for his cause. But he knew that it is fruitless and useless for him as he is not a naive as he shows outside. And Salem give him a booty call. .... Why not? He's immortal. she's immortal. Ozma already left her so why not take her? He has a saying after all. want not. Waste not. but he knows that it won't be easy. But being alone forever until the planet and star dies is just... not an ideal type of life he want. and if there's anything they both have in common... is that they wanted to be free from their prison. after all... Salem reduced the population of humanity due to the constant use of dust. after all... dust is just another form of magic. and without magic. the planet would die and collapse and she prefers that she'd rather die than walk in the desolate planet alone. that is no different from prison. without humans ozpin cannot reincarnate. And with humans, the planet would inevitably fall. And Roman Smith knows that. besides. who doesn't like her anyway? she has a nice Curves and sex appeal.
