All the Diabolik Lovers games have different writers so Dark Fate is just the same but you can actually watch play through videos for More Blood which is what the OVA is based on. You can watch it on youtube. More Blood's storyline takes place a month after Yui moves in with the Sakamaki Brothers so she does know about vampires since she has already lived with vampires for a month.
