บท 651: The suspicious Cube

A suspicious cube stood in the center of the hallway. Arc was in the middle of putting on the blazer of  the academy's uniform, but stopped when he saw it just eerily sitting there on the carpeted floor. Sammy also came out of her room a few moments later, personally not paying much mind to the foreign object.

"What are you doing? We're going to be late," Sammy told her brother with a half-scowl. But Arc was still practically frozen in place, only slowly starting to move in slow-motion to finish getting dressed, "But... it's a random cube."

"So? It's probably just another one of Dad's tests," she replied, and Arc immediately nodded, "Yeah, exactly. So why did he put it here, right in front of my room...? He wanted me to test it, right?"
