"Love is dangerous—especially when your girlfriend is a demon lord."
Naomi Fudokawa never expected his life to get any weirder. A lonely otaku with zero social skills, he was used to spending his days lost in anime and games. But everything changed the night he met Aiko—the mysterious girl with pink hair, scarlet eyes, and a terrifying secret.
Aiko isn’t just any girl. She’s Klaus, a demon lord in hiding, pursued by powerful enemies who will stop at nothing to drag her back to the underworld. Staying by her side means facing danger, betrayal, and the wrath of those who fear her return.
Naomi has two choices: let Aiko go and live a normal life… or risk everything—his peace, his future, even his soul—for a love that could destroy them both.
From neon-lit Tokyo streets to blood-soaked battlefields, this is a tale of forbidden love, epic battles, and the fight to protect the one who matters most.
