That's cool. My OC is the Meister of two dual swords, who happen to be two of his older sibling who are also twins. The thing, the two if the are demon swords because the twins disappeared for nearly 16 years and my Meister OC and their younger brother jJayden reunited with them when he was 13. They've been trying to fight the influence if thd black blood ever since. When they soul resonate they merge into something called the yin-yang buster sword.
