### Volume 2: Upper World
**Chapter 2: Split Paths**
The air in the Upper World was thick, wet, like breathing through warm blood. The vines—trees, whatever they were—swayed slow, sticky barbs glistening under the split sky: one half deep midnight blue, the other a bruised, throbbing pink. Demons crawled out of the pulsing ground in waves—red-eyed things with too many limbs, scales dripping goo, wings tearing open like wet paper. Devils followed, taller, smarter, black horns curling back, eyes glowing yellow with hunger.
Sky stood in front of the group, knife in one hand, the other clenched tight. The second heartbeat—**the Demon Heart**—thumped heavy in his chest, louder than before. He could feel it watching through his eyes.
He turned to the others—Max, Frosty, Hiro, Jefferson (limping), Mira, Cam, Jessica, Juno, Rita, Lola, John, and the four new ones: Kira, Taka, Aoi, Ren.
“I’m staying,” Sky said. His voice was low, steady, but tired. “You guys keep moving. I’ll be fine.”
Max stepped forward fast. “No. Hell no. We don’t split.”
Sky met his eyes. “I have the Demon Heart. The core. That thing inside me? It’s the strongest piece. They’re coming for me. If I stay, I draw them off. You get a clear path.”
Frosty’s hand twitched toward her bokken. “We’re not leaving you.”
Sky looked at her—really looked. “You have to. Joe needs you. The group needs you. I’ll catch up.”
Hiro stepped up, eyes wet but determined. “Okay.” Her voice cracked a little. “But you come back. Promise.”
Sky nodded once.
Kira—the Vein Clan girl—pulled her sword. The blade was thin, red-edged, veins pulsing under the metal like living things. She walked to Sky’s side, stance relaxed but ready.
“I’ll stay with him,” she said simply.
The group hesitated. Max opened his mouth, closed it. Frosty looked like she wanted to argue, but Hiro put a hand on her arm.
If you discover this tale on Amazon, be aware that it has been unlawfully taken from Royal Road. Please report it.
Max exhaled hard. “Fine. But you better not die again, man.”
Sky gave the smallest smile. “Not planning on it.”
The group turned and ran—long strides down the vein-bridge, shadows and frost and lightning flashing behind them as they disappeared into the pulsing pink half of the sky.
Sky watched them go until they were gone.
Then he turned to Kira.
“You didn’t have to stay.”
She shrugged, sword resting on her shoulder. “Someone’s gotta watch your back. Besides, you’re interesting.”
Sky snorted. “That’s one way to put it.”
The demons came first—hundreds, then thousands, red eyes glowing, claws scraping the fleshy ground. Devils followed—taller, black-horned, wings beating slow, mouths full of teeth.
Sky flexed his fingers. The Heart thumped once—almost eager.
Kira moved first.
She spun, sword flashing in a blur—42 frames per second, a single continuous slice that looked like a red arc of light. Five hundred demons fell in one motion—heads rolling, bodies collapsing into black goo.
Sky stepped forward, fist cocked.
He punched the nearest demon—straight through the chest. Bone cracked. The thing exploded backward in a spray of ichor. He grabbed another, stabbed the knife deep into its throat, twisted, yanked free. Blood sprayed hot across his face.
A devil lunged—teeth snapping for Kira’s neck.
Sky moved—Rift Step, spatial fold—and shoved her aside. The bite clamped on his forearm instead. Fangs sank deep. Pain flared white-hot.
Kira’s eyes widened. “No—Sky!”
He ripped the devil’s jaw open with raw strength, threw it aside, blood pouring from the wound.
“It’s okay,” he said, voice calm despite the pain. “I’m immune.”
The Heart thumped again—almost smug.
Sky reached down, picked up the **demon gun**—the one Jaylee had dropped in the courtyard fight. Heavy, black-red, still loaded with rift-rubber bullets. He aimed into the horde.
Three thousand shots.
He fired in bursts—each pull sending compressed threads ripping through demons, mini-rifts exploding on impact. Bodies shredded, goo sprayed, the ground turned slick and black.
The horde thinned, but more came.
Sky crossed his fingers—blue-red energy swirling.
“Ultimate Realm.”
Endless Fracture opened.
The world cracked.
To the outside—0.1 seconds.
To Sky—one full minute.
Demons poured in endless waves—red, black, scaled, winged. He moved through them like a storm: chains whipping, fists echoing, voids erasing. Five hundred per second. Bodies piled, goo steamed, time stretched like taffy.
When it snapped shut, the ground was a carpet of corpses.
Sky stood breathing hard, blood dripping from the bite, cuts fresh across his arms from backlash.
Kira stared at him, sword lowered.
Meanwhile—
The rest of the group ran for hours—vein-bridges twisting under their feet, pink sky pressing down. Max slowed, panting.
“You think Kira likes Sky?” he asked, half-joking, half-serious.
Frosty snorted, wiping sweat. “You like to joke, don’t you.”
Hiro’s cheeks went pink. “Guys… we shouldn’t really be worried about that.”
Max grinned. “What? You like Sky too?”
Hiro stammered. “N-n-no! I don’t!”
Frosty laughed—short, tired. “Yeah right. But anyways… Joe, what should we do?”
Mr. Joe—limping, bandaged—looked up at the pulsing pink sky.
“Just call me Joe.”
Frosty nodded. “Okay, Joe.”
Joe pointed ahead—toward a massive, fleshy structure rising from the horizon, like a heart-shaped fortress made of veins and bone.
“I think they’re in the big house we saw. We didn’t go because Jefferson was scared.”
Jefferson muttered. “I wasn’t scared.”
Het—wait, Het was dead. The memory hit them quiet.
Joe continued. “But we didn’t. Anyway… three hours ago when we first got here.”
Mira nodded. “Yeah. We should go now.”
They kept moving.
Back with Sky and Kira—
The ground trembled.
Ray appeared—rift-stepping from the base straight to them, coat flaring, eyes locked on Sky.
The chapter ended.
