Here are the ways I found of scaring each girl to 210+ bpm. For the sake of explaining, I'll post a translated list of the items. Items written in blue are items that need to be unlocked by capturing the girls

These were all done with the girls having taken a diuretic/laxative
Tsukasa (first girl, twin tail):
Ghost 1 -> Ghost 2
Miyu (second girl, tall tanned):
Vampire -> Ghost 2
Akane (third girl, blonde):
Chime bell -> Surgeon
Riina (fourth girl, long brown hair):
Scream -> Baby
Marimi (fifth girl, glasses student):
Scream -> Ghost 1 -> Vampire
Tokiko (sixth girl, teacher):
Ogre -> Ghost 1 -> Ghost 2
(Interestingly, if you gave Tokiko a diuretic/laxative and she relieves herself in either of the first two turns, this strategy won't work, because she'll faint on the second trap)
I couldn't find a way to get Marimi and Tokiko to faint in two turns, but if anyone finds a way, let me know.
