The Irregular Empress — an AI-powered romance simulation game where merge puzzle gameplay meets deeply personalized fantasy romance. If you love otome games, dating sims, visual novels, or interactive romance games with strong female protagonists, you've just found your next obsession. You've been hired as the Crown Prince's contract fiancée — quick-witted, clever, and very much a temporary arrangement. Your fiancé: Crown Prince Cleorr. Cold, precise, impossible to read. The contract terms are simple enough. The feelings that develop? Anything but. ◆ MERGE PUZZLES MEET PALACE INTRIGUE Solve hundreds of satisfying merge puzzle stages to complete imperial assignments, untangle courtly conspiracies, and advance deeper into palace life. The Irregular Empress is more than a casual merge game — every puzzle you solve moves the story forward and reshapes your bond with the Emperor. Whether you're a fan of idle merge games, match-3 mechanics, or narrative-driven puzzle games, this is an emotionally charged experience unlike anything else. ◆ AN AI ROMANCE THAT TRULY REMEMBERS YOU Crown Prince Cleorr is powered by advanced AI — LLM combined with RAG (Retrieval-Augmented Generation) — meaning he genuinely remembers your past conversations, adapts to your personality, and responds in ways that feel uniquely tailored to you. In this AI romance simulation, no two players share the same love story. Every choice you make today shapes the Crown Prince you'll meet tomorrow. Your words are remembered. Your decisions write the romance. This is next-generation otome game and dating sim design. ◆ PERSONALIZED AI ARTWORK — YOUR LOVE STORY, ILLUSTRATED Most romance games and visual novels show every player the same pre-drawn event CGs. The Irregular Empress is different. Based on your dialogue choices, your emotional tone, and the state of your relationship, the game generates personalized event CGs and short-form video content in real time — uniquely tailored to you and no one else. Your romance isn't just told. It's illustrated, specifically for you, by generative AI. ◆ THE WORLD OF ALPHANSTEIN & THE STORY BEHIND IT The Irregular Empress adapts the beloved Korean fantasy romance web novel by Lock Media. Behind the gleaming ceremonies of the Alphanstein Empire lies a web of ambition, ancient witch legends, and court conspiracies no one dares name aloud. Every courtier hides an agenda. Every hallway conceals a secret. A knight who lived disguised, a contract engagement, a throne she never sought — and an emperor she was never meant to love. Fans of Korean web novels, webtoons, manhwa, and fantasy romance will feel right at home from the very first scene. ◆ AN UNFORGETTABLE CAST Crown Prince Cleorr — cold, calculating, and playfully unpredictable. His carefully guarded composure cracks, slowly, only in your presence. Tissoën — looks like a sword-obsessed fool, but holds deep respect for the allies he acknowledges. Hans — cheerful and dependable. The loyal knight who makes even the coldest palace feel like home. Albina — the former Empress who opposes the Crown Prince. Beautiful and alluring, and deeply dangerous. Konstanze — commands every room she enters, a pure yet captivating duchess. The Crown Prince's half-sister, her true motives remain shrouded in mystery. ◆ GAME HIGHLIGHTS • Hundreds of merge puzzle stages with fully story-driven progression • AI Emperor (LLM + RAG) who remembers your conversations and evolves alongside you • Real-time generative AI event CGs and short-form video rewards, personalized to your playthrough • Branching dialogue, multiple routes, and varied relationship endings • Seasonal events, limited-time story chapters, and continuous updates • For fans of otome games, dating sims, romance simulations, merge puzzle games, and interactive fiction ◆ RECOMMENDED FOR FANS OF Otome games · Dating sims · Romance simulations · Merge puzzle games · Idle games · Visual novels · Fantasy romance · Korean web novels · Webtoons
