About This Game

 -Every line leaves a memory.-

  Ren Takamori is a struggling manga artist facing an impossible deadline. Late one rainy night in Tokyo, he opens an old box belonging to his family and discovers Kuroi Sen—an antique black pen with a power that should not exist.

When Ren completes the drawing of a mysterious woman, she steps out of the page.

   She remembers him. And she is not the only one.

   Kuroi Pen is a choice-driven adult romantic fantasy visual novel about creation, memory, desire, consent, and the freedom to choose your own life. Across six increasingly dangerous nights, Ren must build relationships with the women brought forth by the pen while uncovering its connection to his family and his missing memories.

   -Your Choices Shape Their Lives-

Choose whom to draw, whom to trust, and when to put the pen away. Your decisions influence relationships, jealousy, curiosity, and the truths you can uncover.

The women summoned by Kuroi Sen are not blank characters. Each has her own personality, memories, fears, and desires—and each responds differently to the way Ren treats her.

Can a creation choose its own future?

The deeper Ren investigates Kuroi Sen, the less certain he becomes that he created these women at all. To learn the truth, he must decide whether to keep drawing, preserve the world the pen has opened, or draw one final line.
