After a tragic childhood incident, Mirai Masumoto has always hated the Shinsengumi. In fact, she's on cold terms with just about everyone except her father, the only family she has. But then he goes missing in Japan's capitol. Determined to find him, Mirai travels to Kyoto--only be captured by the Shinsengumi. Go figure. Mirai expects the worst, both for herself and her father. So she's surprised--and more than a little scared--to find out that the Shinsengumi are looking for him as well. Before she knows it, it's settled that she'll be staying with them and continuing her search. And there's only one person who disagrees with that decision more than herself. Souji Okita. The worst member of the Shinsengumi, and by far the most annoying. From day one, Mirai is convinced that he's the embodiment of everything she despises. But the more time she spends with him, the more she realizes the two of them are far more alike than she initially thought. And she's not sure that's a good thing.
