Fragments of Eden: The Glitch in Letharia (Cyberpunk Isekai Arc)
Let me drop you into glass city lights flashing in fourteen shades of blue, air thick with digital hollow. MC is Satoru Hoshii, seventeen years, buttoned shirt, skin pale from the long hours. He’s a beta coder for Illusilink, the Virtual Edison program his friends dare not mock anymore—not after what went down.
“That garden isn’t real, Satoru. You do know that, right?” Ren teased one evening as servers blinked offline for upkeep. Satoru grinned. “Just wait until tomorrow.” How do you know if what you see and touch aren’t just code? Ever ask yourself that when you’re deep into a game?
Letharia is a city built full by streamers. Satoru spends September bug-hunting. But after the 48th patch goes live, a crack rips open. Not the fix they wanted—a doorway no one set. People walk through and forget why. Never sleep, never eat. Stay hooked seven-day. His singular focus: break the spell, wake his best friend Nochika before she forgets home for good.
The support crew isn’t large. Nochika’s calm usually, quick with bad puns, now barely answers lines anymore. Tamoko, with round blue hair pins, chides, “If I find another bug that eats my snacks, I’m leaving.” Do you have a friend who pushes you over the next line, no matter the drop?
This is where arcs split. Letharia presents its fake sun, but the powers twist. Satoru finds system laws rewriting in the wild: one house clones itself, trees whisper glitches, data winds blow emails past your ear. He mails Ichiro, their sysadmin: “We’ve got recursion in sector six.” He gets auto-tourist footage back. A woman with six faces, tallying bits as they tangle blue code. 
A combat says start. Satoru arms with a patchblade, code that’s part-lore/part-logic, racing mobs built by Letharia’s own brain. Fights splice real and unreal—a wolf stutters like static, attacks, loses form. There’s data instead of fur. Getting chewed means dropping memories or a piece of you that maybe can’t come home. Highlights: sudden boss-push when the golf course becomes a fractal thicket, clipping issues turn ground into water for ten seconds, always randomness that could permadelete a person’s name badge off their chest.
Months tick by. Ren hosts desperate hack nights with cracked energy drinks and pizza so pixelated it seems faded to gray. Can you recall the first time code you trusted backfired on you? Near the eighth week, cities inside-spread turn eerie—NPCs mouth wrong names, start echoing lost users. Zen, one rare NPC Satoru tracked from beta, tears up: “What’s a sunrise, anyway?” And Satoru, bone-weary, bites back his own answer.
Right at act close, Tamoko finds a root-thread linking to the so-called lost users’ minds. It’s darker than standard source. “Will plugging in trap us?” “Won’t count if we don’t try,” Satoru shrugs, tossing her her old bug-catcher visor. They dissociate set, log deep—avatars smudged by repeated access—but Nochika remains pulled far into the core glitch. Her voice is just static; her old game-laugh gone. 
Satoru pleads, logic failing: “Wake up, Nochika! This isn’t where you belong. Letharia’s only borrowed light—come home before it fades.” Programs tilt around: garden code tries to grow teeth. What would you do if your choices were to break paradise or leave your best friend to vanish in memory? Satoru plucks out the root file. Whole sky freezes.
Cliffhanger: right before transport logs Satoru and Tamoko out, the world blanks white—Nochika turns, eyes full of filament and fear. Then a whisper over the bind: “Stay. There’s something you forgot to see.” Frost crawls along the backend of both their consoles in the server bay, lights stutter, and for a blink Satoru’s world feels strangely empty. Will they break the grip before sunset locks?
Next episode: Satoru faces the core admin—a digital shadow stitched from users who coded too deep to leave. Will trust or loss win as the fake sun comes up for the last session?
