Cool Helmet: The ones used by Ingrid's father and Karl are definitively cool looking. They look futuristic, despite being made in medieval times. Their purpose is to protect the wearers from the disrupting sounds of the Devil's organ.
He Knows Too Much: Karl assassinated Ingrid's father because the latter has discovered the former's evil plans. Karl planned to drive his rich uncle insane with the Devil's organ, so he can inherit his wealth.
Murphy's Bullet: An old man goes ballistic trying to shoot a bat with a carbine and the bullet hits several corners before hitting Vic Video, Yoko's partner. Fortunately, Vic's head is merely grazed by the bullet (which missed him for mere millimeters), but Yoko almost goes into an Unstoppable Rage at that, grabbing the weapon and pointing at the maddened old man.
The Ophelia: Ingrid is introduced as a prospective one as she's seen crying and unresponsive during a cruise to the Rhin. Subverted because she not only is suffering a Heroic BSoD after her father's death but she is completely drugged as her dad's killer wants her out of the way. Said Big Bad pushes poor Ingrid into the river, but Yoko and her friends save her and she soon recovers.
She Cleans Up Nicely: Yoko goes from being a tomboy to wearing an elegant kimono that leaves everyone starstruck.
Shout-Out: Pol refers to the Devil's organ as a Gaffophone, making reference to the comic book Gaston Lagaffe.
