A/N: I hate cross overs. But this was worth it.
Lenalee was hanging out with a new man ever since she got back from Russia. Kamui began to follow her and this man around. One day, Kamui saw another girl following the pair. Kamui tapped her on the shoulder.
"Are you following them?"
"Yes."
"Why?"
"That is my brother. I want to marry him."
Kamui thought this to be perfectly normal and decided that a forced incestuous relationship between his sister and himself would not be a completely bad idea.
"I shall join you!"
