Diabolik Lovers: Yui's Brother [Rewritten One]

Yui Komori and Yuuki Komori were sent off to live with a 'friend' of their 'father'. For a good reason too [but was it the one they thought it was?], what will happen when they meet the sakamaki's?
Does Yuuki recognize the sakamaki's? and who- what is yuuki komori?

Life changes for the good and bad indeed.
