Leon Vale’s world stopped when the chamber labeled him F-Rank, no spark, just Empty Core.One dozen sparks in a sea of a thousand chances. A near-miracle of failure, somehow flopped harder than flatlining.In Neo-Veridia, strength rules the game, no exceptions. Those who are tough get hailed as champions; others? They're stuck cleaning up messes. Might makes right here, plain and simple.Leon ended up on the ground. That’s where he landed, no surprise there.Later, the red moon climbed into view. Right after, creatures smashed past the shield. His siblings stood near death yet deep in his Empty Core, an old force stirred awake.[ SHADOW EXTRACTION SYSTEM ACTIVATED ]Leon takes energy from whatever he defeats. Each time a creature falls, he gains more strength. As shadows vanish into him, he drifts toward a mystery - something waits in a space beyond places: a seat atop no land, while a voiceless headpiece calls out to him through empty dark.Yet taking what’s not yours brings trouble.On top of everything else, the Evernight Alliance caught wind. Not just vampires - werewolves too. Old creatures that oughta be myths are poking at the city’s walls, messing up dungeon cores, chasing whatever’s pumping out that dark energy signal.Hunting for him.Leon’s stuck in a risky move, quietly getting stronger so he can shield his folks, hitting school while sneaking around to pull out shadows, acting powerless even though some old, grim force now names him successor.That F-Rank tag? Total fake. His Empty Core isn't broken, it fights. Each darkness he swallows drags him nearer to a reality he can’t face yetNot every seat of power fits a hero.Some crowns come from shadows, built on bones.Some kids just inherit stuff whether they like it or not.The Crimson Moon marked the start. What’s coming next? Things are about to heat up.
