Subaru:  Subaru answered with a curt wave of his hand, signaling there was no problem.

Julius:  Concluding that his opponent had accepted from his gestures and expression, Julius nodded. “The referee shall be—Ferris.” Julius glanced sideways at him, while Ferris casually lifted up his palm and waved back.

Ferris:  “Sure, suuure.” He’d easily accepted the role of referee. There was no way to know what he thought on the inside. Unlike Reinhard’s hope to put a stop to this, Ferris seemed all too eager to get things under way. “Have at it, you two. No matter what horrible wounds you suffer, Ferri can patch you up as long as you don’t actually die, Subawu, so good luck!”

Subaru:  “Why say that to just me? Worry about the other guy, geez.”

Ferris:  “Meow, what strong resolve! Hear that, everyone? All right, one, mew, three!” Turning to the onlookers, Ferris raised both hands high and brought them down. At his signal, the parade square erupted in uproarious laughter, pouring scorn on Subaru’s reckless words.

Julius:  When Julius offered him one of the practice weapons, he gripped the hilt firmly, as if he was used to it. Similarly, Julius gripped the other waster and announced the start of the mock duel. “At least you are enthusiastic. Shall we begin?”

Julius:  “—”

Subaru:  Subaru’s hand let the wooden sword go a moment before Julius’s fingers could take it. Naturally, gravity caused the waster to fall. Julius instantly bent forward as his hand chased after it. The knight, his body curved forward, had lost his height advantage over Subaru. “…Hmph.” Subaru stepped forward and flipped the waster in his hand from down to up, aiming squarely at the tip of Julius’s chin. Simultaneously, his left hand thrust straight forward, tossing the sand he’d covertly picked up during his warm-up exercises toward Julius’s eyes—a classic blinding, two-step surprise attack.

Subaru:  —Got him now, thought Subaru, smiling with malicious satisfaction at his little trick. The next moment, he heard a voice right against his ear.

Julius:  “It seems that you truly have no shame—It must make the vulgarity easy to come by.” Simultaneously, a blow struck Subaru. He felt a sharp, hard jab right to the solar plexus. The shock to his torso shuddered through the rest of his body.
