貴方は私の旦那さま

As she started getting used to the Shinsengumi, Chizuru began to have odd dreams. Hijikata, Saitou, Okita, Harada; they've all been proclaiming themselves to be her husbands. Being a demon, there's no way she could live happily as a human. Just as she started forgetting about those dreams, they started coming back to her in real life... These are the many happy futures she could share with her beloved husbands. [translated from the official website]
