The Demon King's Army

"Ugh, stop smirking like that. You look more annoying than you already are."

"Hoh? Am I smirking?"

"You are." Millonia looks at me weirdly. "I didn't expect having a sword could get you that excited."

"It's not just any sword, Millonia—it's a Blue Rank Relic." I smirk. "I can do much more things with it."

"Whatever."

Looking down at my right hand, I can see another symbol carved on it, right below below the Demon King's Mark. 

The sword like symbol signifies the establishment of the bond between me and Rexorem—a Bond Seal. Instead of carrying it around on my back, I can store it inside the Bond Seal, and summon it whenever I want.

"Have you already figured out the way to summon your sword?" Millonia asks.

"I would have been freaking out upon noticing that my sword had gone if I hadn't," I answer blandly. "I immediately knew how it worked the moment I bound Rexorem with myself."
