Colossal Dominion: Ruka's Ascent

Chapter 1: Ascension's Burden

I never asked for this. The world was already a shattered mess—war, greed, and despair gnawing at every corner of humanity—when the heavens split open, and a voice, ancient and unyielding, declared me a Peacekeeper. Me, Kanata Ruka, a trembling middle schooler who couldn’t even stand up to bullies, now towers over the entirety of Honshu at 1,500 kilometers tall. My body is a landscape, my footsteps cataclysms, my breath a storm. But inside, I’m still that scared little girl, clinging to the only thing that keeps me sane—my Onii-chan, Tenichi.

I can feel him now, nestled against the curve of my collarbone, his tiny form a faint warmth against my endless expanse of skin. He’s so small, a mere speck against my vastness, yet his presence is the only thing anchoring me to who I was before. The divine intervention that reshaped me didn’t just alter my size; it carved something primal into my soul, a hunger I can’t name, a need that burns hotter with every passing day. And Tenichi, poor, awkward Tenichi, is caught in the crossfire of my transformation.

‘Ruka, you’ve got to focus,’ his voice crackles through the tiny communicator I’ve rigged to hear him over the howling winds of my own breath. ‘The northern factions are rioting again. They’re calling you a tyrant. You can’t just… loom over them and hope they behave.’

I tilt my head slightly, careful not to dislodge him, though the thought of him slipping down the slope of my chest sends a forbidden shiver through me. ‘Tyrant?’ I murmur, my voice a low rumble that shakes the earth below. ‘I’m trying to save them, Onii-chan. Why can’t they see that? I could crush their cities with a single step, but I don’t. Doesn’t that count for something?’

He sighs, and I can almost picture his exasperated expression, even if I can’t see it. ‘It’s not about what you *could* do, Ruka. It’s about what they *think* you will. You’re a goddess to them now, whether you like it or not. And goddesses don’t exactly chat over tea.’

I smirk, a gesture that probably looks like a canyon splitting open from his perspective. ‘Maybe I should. Invite their leaders up here for a little… heart-to-heart. I’ve got plenty of room on my body for a summit meeting.’ My tone drips with dark humor, but there’s an edge to it, a heat that I can’t suppress. The idea of tiny, insignificant beings crawling over my skin, worshipping or fearing me—it stirs something deep, something I’m not ready to face.

‘Ruka, don’t joke like that,’ Tenichi snaps, his voice tight. ‘This is serious. And… can you at least move me somewhere less… uh… compromising? I’m literally clinging to the edge of your damn neckline. One wrong move, and I’m sliding straight into—’

‘Into what, Onii-chan?’ I interrupt, my voice a purr that vibrates through my colossal frame. I shift ever so slightly, letting him feel the subtle quake of my movement, knowing full well where he might end up if I’m not careful. ‘Afraid you’ll get lost in me? I’d find you. I always do.’

‘Ruka!’ he barks, and I can hear the flush in his tone, the awkwardness that always creeps in when I tease him like this. ‘This isn’t funny. I’m trying to help you, not… not play some weird game of hide-and-seek on your freaking body!’

I laugh, a sound that rolls like thunder across the horizon, and I feel a rush of power, of control, that I can’t ignore. ‘Oh, come on, Tenichi. You’re the only one I trust up here. Where else am I supposed to keep you? My shoulder? My palm? Or maybe…’ I pause, letting the suggestion hang heavy in the air, ‘somewhere a little more… intimate?’

‘Stop it,’ he growls, but there’s a tremor in his voice, a crack in his resolve that sends a jolt of heat through me. I shouldn’t push him like this, I know I shouldn’t, but the weight of my new reality, the crushing loneliness of being a living mountain, makes me crave something—anything—to feel human again. And Tenichi, my sweet, stubborn Onii-chan, is the only one who can give me that.

I lower my gaze to the fractured landscape below, where cities tremble in my shadow, and I feel the ache building, a need that’s as vast as I am. ‘Fine,’ I whisper, my voice softening, but there’s a dangerous edge to it now, a promise. ‘But you’re staying close, Onii-chan. I need you. And tonight, when the world quiets down, we’re going to talk. Really talk. I’m not just a Peacekeeper. I’m still Ruka. And I’m… I’m burning up inside.’

I can hear his breath hitch through the communicator, and I know he feels it too—the tension, the unspoken heat between us, magnified by the sheer impossibility of our situation. My skin prickles with anticipation, my colossal form aching in ways I can’t articulate yet, but I know where this is heading. Tonight, under the cover of darkness, with the world at my feet and Tenichi pressed against my endless curves, I’m going to let go of the last shred of restraint. I’m going to show him just how much I need him, how hard my heart pounds, how wet and dripping with desire I’ve become in this godforsaken body. And when that moment comes, when I feel him against me, tiny but so vital, I know I’ll be panting, sweating, horny beyond reason, ready to explode in a way that might just shatter the earth itself.
