The Red Moon Apocalypse

A blood-red moon descends upon the world, and a mirror realm from another dimension tears open a gateway into reality. Monsters run rampant, and humanity's minds begin to twist. The male protagonist unexpectedly awakens the power to devour, allowing him to grow stronger at an astonishing pace by refining otherworldly beings. But this power erodes his soul with every passing moment. The secretive organizations around him each harbor their own agendas, the true loyalties of his companions are impossible to discern, and the trials of the Seven Deadly Sins threaten death at every turn. Only when every clue has been revealed does he learn that the red moon was never a natural disaster, but part of a grand scheme to manipulate all of humanity.
