No. The Catastrophe light novels take place in the year of the Apocalypse, so Yu, Mika, Shinoa, and the others are only seven or eight years old. Mika and Shinoa meet each other, but they're too young for any romance going on. The romance is between Guren and Mahiru, who created cursed gear. It's a rather tragic and intense action series. The first two volumes come out in an omnibus in English in a couple of weeks. Guren becomes a father figure for Yu in the Vampire Reign manga, and he is one of the main characters.

The Story of Michaela light novel series details Mika's life story as well as the histories of the other vampires, but there's not much information out about it yet since it only came out in Japanese last month. I haven't heard about any romance in there either.
