The city shook. Mr. Sini quietly removed his glasses and gently placed them on his desk. He was older, sporting a few wrinkles on his dark skin and several grays in his beard. He wore a black suit, one made for business instead of combat.
All around him was destruction. His newly created lab in Rose City was in ruins. He had created Sini Corp shortly after Lucifer was truly defeated. While Full Monarch decided to follow Nier's final example and throw himself into hero work, he had settled on a different path.
Before the Calamities, they say humans stood at the top, that they were far more advanced. It had taken nearly fifty years and the work of every Super he knew, but gradually, Sini had brought the world back to its true self. Now, though, it was all in ruins once more.
His building was falling apart. Black flames ate away at the walls. Most of Rose City was already gone. "If you wanted my attention, rest assured. You've gotten it," he called out.
Outside his building was dirt. The road, the street, the buildings, the cars, the people, and even the city had been wiped clean off the map in a one-mile radius, leaving just a flat stretch of land directly outside his front door. At the very edge of this bizarre, strange new battlefield that had been created, Sini saw him—his once-long-time friend.
The thing might have been Nier once, but he wasn't that hero any longer. A twisted, jagged throne created from living flesh had been forged directly at the edge of the arena. The Emperor's proper form was blacker than even darkness itself, melding in with the wisps of night. What he could see, though, was a pair of glowing blue eyes that stabbed out of the black void that rested on the throne. He couldn't make out arms or legs or anything like that, but he could feel the thing's tremendous power. A power that was rivaled only by the other Calamity threats.
Directly in front of the shadowy throne, the Emperor's bodyguard stood. Hell Hound wore blood-red armor, something she had been gifted from her dark master. Sini traced her form as she walked forward slowly. In her hand, she gripped a jagged mace, one stained in blood—her weapon, the very same that had shattered dozens of heroes' skulls. Able to negate and cancel out weaker powers.
Sini strolled forward, walking out of his building. He stopped fifteen meters away from Hell Hound as he and the villain glared at one another. "You could have just knocked if you really wanted to speak with me. This destruction was uncalled for, Nier. I know that you're hurting, but this isn't the way. This isn't what she would have wanted-"
Hell Hound's fingers grew tighter on her weapon, and he could see her eyes narrow. "You have no right to speak as if you know who the master is or what he's gone through. He is not Nier."
"I'm the one who raised him. I have every right." Sini sighed. "But you're right. He isn't Nier. Not anymore. He's become something worse than the very monsters he creates."
"I'm going to teach you a lesson." The monster hissed, crouching low. "One you should have been taught long ago."
"Oh? And how do you plan to do that?"
"I planned on hitting you so hard your head pops, and I'd get to see the inside of your skull."
"I see." A ring of water began to slowly twirl into existence around Mr. Sini. "It's been fifty years since this old man bothered to fight. That said, I hope you don't think I've gone soft-"
Hell Hound was on him in an instant. Moving faster than most pro heroes, she swung her mace down so hard that the world had trouble keeping up, space twisting and bending to her will. Sini's water barrier barely had time to rise up and block the strike, and even then, the force of the attack was enough to send him flying back. His water struck out like a whip, but Hell Hound twirled herself around and slammed her weapon down onto the wave, sending a powerful shock wave through it that was so hot and fast it caused the water to instantly boil and turn into steam.
