"You are hereby expelled from the cycle of rebirth."
Those were the final words Rin heard before darkness swallowed him whole. Not death. Not peace. Just… a void full of judgmental a-holes with wings.
● Earth – The End
Rin Katsuro was 19. Genius-level IQ. Shut-in. Created the first AI capable of rewriting global infrastructure.
Also the reason half of Tokyo's traffic grid glitched out and every toilet flushed nonstop for three days straight.
"Bro, I just wanted to make a waifu simulator," he muttered as soldiers surrounded his one-room apartment.
And then came the gunshot. Then… the voice.
"Your soul is contaminated. You defied the divine order. You shall not be reborn again."
"...Get stuffed."
Those were his final words before everything shattered.
● Ereborn – Glitched Resurrection
Pain. Fire. Screaming. And…
Boobs?
Rin blinked. He was lying on a stone bed. His body felt… different. Bigger. Stronger. Covered in black armor with glowing red runes. A demonic sword pulsed nearby, whispering something creepy in Latin.
A little girl with red horns sat beside him, clutching a teddy bear. She looked up with teary golden eyes.
"P-Papa? You're awake…? Mama's gone… They said you died…"
W H A T.
[System Error: Unknown Soul Detected in Vessel ID: Valtazar the Tyrant][Soul Sync in progress... Loading corrupted memories…]
Suddenly, visions poured into Rin's mind—memories of war, blood, destruction, and being the Demon King's right-hand man.
He'd been reincarnated into Valtazar, a literal demon war criminal.
Oh. Oh, no. Oh, f—
The little girl hugged him tightly. "Please don't leave me again, Papa…"
Something cracked in Rin's heart.
He didn't know this girl. But she looked like she hadn't slept in weeks. She trembled. She held onto him like her life depended on it.
And in that moment… something clicked.
"I'm not going anywhere," Rin whispered, resting a hand on her head. "You've got me now."
The system pinged again.
[Error Magic unlocked: "Parent Protocol – Bugged Fatherhood Achieved"]
[Skill acquired: "Emotional Firewall – Immune to Charm-type effects when daughter is crying."]
[Hidden Quest Activated: Protect Lilith. Failure = Eternal Damnation]
Rin blinked.
"...What kind of messed up parenting simulator did I get isekai'd into?!"
● Outside the Fortress
As Rin (aka Valtazar) stood up, the ground trembled. A massive army of holy knights approached from the horizon, banners raised, blades shining.
"By decree of the Divine Empire, surrender the girl or be purged, Demon Scum!"
Lilith hid behind his leg.
Rin cracked his neck, eyes glowing with glitchy red code.
"I've been awake for five minutes, and already some righteous bastards want to kill my kid."
He picked up his demonic sword.
"Guess I'm back online."
