^ Yeah, it's from Stacies.
Near the end of the musical, Ayumi's character is the first Stacy who has shown the ability to speak and control her hunger for human flesh.
Her boyfriend is unwilling to give her up to the Romero Repeat Kill Squads, so they run off together.
He protects her and Ayumi gives a speech about them becoming the Adam and Eve for a new race. (You can hear some of this in the recording)
This part of the story is when Fukuchan goes crazy for Ayumi's cuteness and expresses her longing to be Ayumi's boyfriend.
...Kinda makes you wonder about Fukuchan's intentions, doesn't it?
