Blades of Extinction

A century ago, an unstoppable species descended upon Earth, wielding powers beyond imagination.
When all hope was lost, a legendary warrior arose, harnessing the might of the Black Dragon to seal them away and wipe out 80% of their ranks.
Now, the seal has begun to weaken, and ancient horrors stir once more.
Renji, an unassuming young man, inherits the Black Dragon's power destined to challenge the monsters of old.
As war looms again, he must master this dark force-or watch humanity fall.
