I Have the Supreme Divine Register. What Do You Have?

[Fantasy, wish-fulfillment.] What does it feel like to outclass your enemies as easily as eating or drinking? Switching between different elements at will sets him on the path to invincibility. They steal my place as the top scholar and bully my maid? Of course I’ll kill, kill, kill. They want to frame me? Of course I’ll kill, kill, kill. They insult my maid? I’ll chase them down and wipe out their entire clan. What? They think I have no one backing me? My card-based martial soul will teach them a lesson. Kill, kill, kill!
