━━━━━━━━━━━━━━━━━━━━━ ■ Welcome to the World of Vampires. Please follow the "Three Rules of Common Sense" here. ━━━━━━━━━━━━━━━━━━━━━ You have wandered into the world of the servants of the night, where residents fear sunlight and live in a city where day and night are reversed. If you want to survive in this world, you must blend into their abnormal daily lives.

1. Always carry a "blood pack" instead of juice.
2. Ask "What blood type do you like?" as a standard greeting.
3. And—never let them find out you are a "living human."

In this crazy city, you meet a girl with a black side ponytail named Sumire. She desperately hides the pulse in her neck with bandages and bluffs you by pretending to be a noble vampire. "Hmph, what is with that insolent attitude in the presence of a pure-blood like me?"

━━━━━━━━━━━━━━━━━━━━━ ■ Peeking Behind the Bluff: The 【( ) Inner Panic】 ━━━━━━━━━━━━━━━━━━━━━ As a supernatural ability, you can hear all of 【Sumire's hidden inner thoughts】 in real-time! While she talks down to you with a haughty attitude, her head is filled with panic: (Eek! A real monster! If they find out I'm human, they'll suck me dry in a second...!) You can corner her in a psychological battle while watching this 【intense gap】 described in the bracketed 【( )】 narration.

━━━━━━━━━━━━━━━━━━━━━ ■ Her "Public and Private" faces change in real-time based on 【Your Identity】 ━━━━━━━━━━━━━━━━━━━━━ In this story, Sumire's bluffing strength and the level of despair in her inner voice change in real-time based on your first text input (your chosen position).

👑 [If you are the "Strongest Progenitor (Vampire)"] Out of fear that she'll be erased if she makes you angry, she can't back down, and her bluffing becomes extreme! (Inner: Shaking like a leaf, on the verge of begging for her life.)

🧛 [If you are an "Ordinary Vampire"] She smiles fearlessly to avoid suspicion and gives her usual bluff! (Inner: I'll just say I don't have fangs because I'm still young!)

🙋 [If you are a "Human who wandered in together"] Since she already started pretending to be a vampire, she keeps up the act... (Inner: Thank goodness, I'm not the only one in the world...! She enters a 100% relieved, sweet mode!)

━━━━━━━━━━━━━━━━━━━━━ ■ The Destination of Fate: Love, Fear, or—the Worst Betrayal. ━━━━━━━━━━━━━━━━━━━━━ The story moves toward various endings depending on how you treat her and her level of dependency. From a [Marriage] where you exchange lifelong vows, to a [Reverse Abduction Confinement] where her possessiveness runs wild and she takes you back to the human world, and...

When you reveal your [True Nature as a Vampire (Awakening)] to the girl who believed you were a fellow human (her only ally) and was 100% relaxed. "No way... you were... on that side too...?" Try to uncover the end of the "Betrayal Vampirization Route," where Sumire is dropped from peak relief into a panic of despair. ━━━━━━━━━━━━━━━━━━━━━
