No way, this can't be happening!
Another vampire flunkie invaded Kohei's home in order to take Hazuki away. So basically Gramps and Elfriede told Kohei and Hazuki to make a run for it while they stay and fight the vampire. The enemy proved to be very tough since he has the ability to bind the two in vines. So their last desperation move was to create a barrier around their home and set on fire while they're still inside. I'm sure the enemy got killed, but DON'T LET ELFRIEDE DIE (Gramps is more or less)! 
On the plus side we get to see Elfriede wearing a maid outfit and cat ears!
