Episode 6 of Dance in the Vampire Bund, “From Dusk Till Dawn” (フロム ダスク ティル ドーン), starts out right when Akira and Yuki get clothed again and part way, which is when Mei Ren shows up to make fun of Akira for not acting like a proper hot-blooded teenager. She also claims that Mina is a lot more devious than he gives her credit for, among them how Mina was actually drawing out her enemies when she supposedly met Akira alone, while in fact being protected by hidden forces. Looks like Yuki interpreted things accurately, after all.
Meanwhile, Mina is pretty happy with how the prime minister capitulated from his opposition to the vampire settlement. The ploy with kidnapping his grandson worked, using plausible deniability to shoot down outright accusations that she is responsible. And the touch with claiming that the grandson would have been turned into a vampire (and actually doing so) just makes the capitulation that much more certain. The biggest reward for Mina must be getting the name of those who had pushed the prime minister to oppose her plans, though.
On the other hand, Akira is not so happy with the questions that Mei Ren raised. It does not help at all that vampires are spreading among the student body and the discovery that Mina is responsible for the kidnapping of the prime minister’s grandson. The Machiavellian response from Mina, putting a lower priority on the students’ safety compared to “other stuff”, is the icing on the cake, although the predictably negative reaction from Akira shuts down Mina’s happy mood as well.
Akira decides to fight against the plague of vampires at the school until he can figure things out, and the still-human students gather at the church for safety until night passes. He had emphasized that all exits should remain shut no matter what while he went out for weapons, but unfortunately no one seems to have thought of the possibility that one of the humans might also be part of the problem. And soon enough, they open the door to let Shinonome Nanami in, who claims to have escaped the vampires but in fact has become a fully cooperating vampire herself. With the human students in the church pretty much defenseless, the next episode is not going to be pretty.
