Chapter 1: The Mask Slips
The arena thrummed with the raw energy of the underworld, a coliseum carved from obsidian and lit by flickering hellfire torches that cast long shadows across the packed stands. Devils of every rank crowded the seats—nobles in their finery, lesser demons snarling bets, and a smattering of fallen angels lurking in the upper tiers. The air hung heavy with sulfur and anticipation, the Rating Game broadcast to every corner of the devil realm. This wasn't just a match; it was a spectacle, a clash between the upstart Gremory peerage and the arrogant Phenex heir.
I stood in the center of the scorched earth, my body clad in the simple school uniform I'd adopted for this charade. Issei Hyoudou, the perverted high schooler with a knack for stumbling into power. That's who they saw. That's who I'd been pretending to be for months now, ever since I slipped into this world to observe. My brother—God, the architect of it all—had cast me aside, unaccepted, unfinished. But curiosity burned in me like a forbidden flame. Why create this chaos? Why imbue these beings with such fragile, fervent souls?
Riser Phenex sauntered into view opposite me, his golden hair gleaming under the lights, wings of flame unfurling behind him like a peacock's display. He smirked, that entitled curl of his lips speaking volumes about the pride swelling in his chest. He was the epitome of it—human arrogance wrapped in devilish immortality, a boy who thought regeneration made him invincible. 'Perverted dragon boy,' he'd called me earlier, his voice dripping with disdain. As if his own leering gaze on Rias hadn't betrayed the same base hungers.
The referee's voice boomed, signaling the start. Riser didn't waste time. He launched forward, fire erupting from his palms in a blazing arc that scorched the ground where I stood a heartbeat before. I dodged, my body moving on instinct honed from eons of watching, not fighting. Not really. I'd cataloged battles across creations—wars of gods, skirmishes of mortals—but never felt the pull. Why fight? Why pour your essence into blows that could end in dust?
'You think you can touch me?' Riser laughed, summoning a volley of fireballs that rained down like meteors. I weaved through them, the heat singeing my sleeves, the crowd roaring as explosions bloomed around me. Pain registered—a sharp sting on my arm—but it was distant, like echoes from a dream. I'd seen humans bleed, devils regenerate, angels fall. It all blurred into data points for my observations.
But something stirred as Riser closed in, his fist wreathed in flames slamming toward my face. I blocked it with my forearm, the impact jarring through bone, and countered with a punch to his gut. He staggered back, grinning through the pain, his body already knitting itself whole. 'Is that all? You're nothing without that dragon arm of yours.' He glanced at my left side, where the Boosted Gear lay dormant for now. He wasn't wrong; I'd been holding back, playing the part.
We circled each other, the arena a canvas of craters and lingering smoke. Riser pressed, his attacks a relentless barrage—kicks that trailed fire, punches that aimed to crush. I parried, dodged, struck back when openings appeared. Each hit landed with calculated force, enough to hurt but not to end it. The audience cheered Rias's name, then mine, their voices a cacophony of hope and mockery. Rias watched from the sidelines, her crimson hair framing a face etched with worry. She'd dragged me into this, her pawn, her ally. Did she sense the facade? Or was I just another piece on her board?
Midway through, Riser changed tactics. He summoned illusory clones, each a mirror of his smirking self, flames dancing around them. They swarmed me, fists and feet flying in a dizzying assault. One caught my jaw, snapping my head back; another drove a knee into my ribs, cracking bone. I gasped, the pain sharpening, pulling me from my detachment. Why did it hurt like this? Not the physicality— I'd witnessed galaxies collide with less emotional sting—but the intent behind it. Riser fought not just to win, but to dominate, to prove his superiority. Pride fueled every swing, entitlement every taunt.
'That's for thinking you could marry my fiancée!' he snarled, a real fireball exploding against my shoulder. Fabric burned away, skin blistering. I dropped to one knee, the world tilting. The clones faded as he approached, towering over me with wings spread wide. 'You're done, Hyoudou. Yield, and maybe I'll let you crawl away.'
The crowd hushed, sensing the end. Rias's voice cut through, sharp and desperate: 'Issei, get up!' But I didn't move at first. Time slowed for me, as it always did in moments of true observation. The arena blurred at the edges, the noise fading to a hum. I looked up at Riser, really looked. His eyes burned with that human fire—arrogance, yes, but laced with fear. Fear of loss, of irrelevance. He fought for honor, for the girl he claimed, for the legacy that defined him.
And in that pause, something cracked within me. My eyes—brown, unremarkable in my human guise—shifted. The audience gasped as the color drained, replaced by an ancient void, timeless and depthless, like staring into the abyss before creation. Whispers rippled through the stands: 'What... what is that?' Devils leaned forward, angels in the shadows narrowed their eyes. Even Riser faltered, his cocky grin slipping.
I rose slowly, the pain receding into clarity. The mask—the carefree boy, the observer—fractured. 'I never understood,' I said, my voice echoing not just in the arena but in the souls around me, carrying the weight of eternities. It wasn't a shout; it was a revelation, soft yet piercing. 'Why this mattered. Not before. Not even now. But... I see it. I finally see why he made you like this.'
Riser blinked, confusion warring with rage. 'What the hell are you talking about?'
He charged again, flames roaring to life, but I met him head-on. No more holding back. My fist connected with his chest, not with brute force, but with truth infused—a strike that resonated through his regeneration, shaking his core. He flew back, crashing into the barrier wall, cracks spiderwebbing the magical shield. The crowd erupted, but I ignored them. Each movement now carried purpose. I advanced, dodging his counter-flames with fluid grace born of cosmic sight.
'Why do you fight?' I asked, my voice threading through the chaos as I grabbed his arm mid-swing, twisting it until bone snapped. He yelped, flames sputtering, but healed almost instantly. 'Is it pride? That fire in your veins—does it warm you, or just burn everything around you?'
He wrenched free, blasting me with a point-blank inferno. Heat enveloped me, charring clothes and skin, but I pushed through, tackling him to the ground. We rolled, fists flying—his punches landing with explosive force, mine delving deeper, probing the why beneath the what. 'Entitlement,' I murmured against his ear as I pinned him, knee driving into his thigh. 'You think the world owes you Rias, your family, your immortality. But it's not given; it's fought for. Clung to. Loved, even when it hurts.'
Riser bucked, flames erupting between us, singeing my hair. He kicked me off, scrambling up, wings beating to lift him airborne. 'You're insane! Shut up and fight!' He dove, a phoenix in descent, talons extended wreathed in fire.
I met him in the air—how, I didn't know, my body defying the human limits I'd imposed. Boosted Gear activated unbidden, red scales crawling up my arm, but it was secondary now. My other hand caught his throat, slamming him down into the dirt. Dust billowed. 'Why do you live like this? Risking everything for honor, for love, for destruction?' The questions poured out, each word a judgment, an empathy, a mirror held to his soul. The audience watched in stunned silence; Rias's eyes widened, realization dawning. I wasn't her pawn. I was something older, something vast.
Riser gasped under my grip, flames flickering weakly. 'Because... because I have to! It's who I am!'
I released him, stepping back as he coughed and rose, battered but unbroken. The fight shifted—no longer a brawl, but a dialogue in violence. He lunged, I countered; each exchange peeled back layers. His pride cracked with every block, his arrogance yielding to glimpses of vulnerability. I struck his side, ribs giving way, and whispered, 'You hurt because you care. You love because it scars. That's the mess he wove into you.'
The referee hovered, uncertain, as the battle dragged on. Minutes stretched, the arena a ruin of fire and fissures. Riser's attacks grew desperate, his immortality a curse now, forcing him to endure the unraveling. Finally, as he summoned his ultimate blaze—a conflagration that lit the sky—I stepped into it. Flames licked my skin, but my eyes held his, ancient and unyielding.
'You destroy to affirm you exist,' I said, emerging unscathed, grabbing his wrist and twisting until the fire died. He collapsed, spent, regeneration slowing under the weight of revelation. 'And in that, you live. Truly live.'
The bell tolled—victory for Gremory. But as the crowd surged to their feet, cheering wildly, I turned away. The mask was gone, shattered in the heat of the fray. Rias approached, her hand on my arm, questions in her gaze. 'Issei... what was that?'
I met her eyes, the void in mine softening just a fraction. 'Understanding,' I replied. 'Finally.'
In the stands, whispers spread like wildfire: Who was he, really? A devil? A dragon? Something more? And across realms, perhaps even to my brother's distant throne, the questions echoed back: Why create them so fiercely alive?
The fight wasn't won with power. It was claimed with sight—the cosmic lens turning inward, revealing not just Riser's soul, but my own.
