Mysterious Cards: I Have a Card Collector’s Compendium

[Urban high martial arts + paranormal + cards + sequences + supernatural abilities + no System] “I'm... Su Chen, a high school student.” “I'm also a holder of a strange card, and a member of the Nether Guard...” “You ask why I joined the Nether Guard?” “Because I have gazed into the abyss... So I shall stand above the heavens... My blade cleaves through the darkness, my sword shatters the Nine Hells!” The paranormal is no legend. These entities lurk in the shadows of human society. And when they run rampant and shatter the balance, there are people... who hide beneath the night sky, standing within the abyss. A black coat, a long blade, and a battle few know about... A paranormal upheaval ten years ago, and the strange entities that vanished! A card codex ten years later, and shadows that invade! Is this the beginning of the world's destruction, or the first sign of its salvation? “Why did you come this far?” “...For reasons I know better than anyone.”
