Fridge Brilliance
- At first glance, it may be confusing that, while the other members of Dark Joker have spade marks on their hands, one member (the one who sold cookies) had his on his forehead. However, remember that Ririka is Nurse Angel, and according to the Book of Revelations, the Mark of the Beast is taken on the right hand or the forehead. It's a reference to Christianity. After all, why wouldn't Nurse Angel's enemies be comparable to followers of the devil?
Fridge Horror
- In the fourth episode, Herb's supposed owner shows up and, as thanks to Ririka and Seiya for finding "his" dog, invites the two of them into his house for cake. The cake is drugged. Of course, the man turns out to be Keto, who just wants to kill Ririka, but the whole situation is eerily reminiscent of the whole "don't go anywhere with a stranger" thing.
- In episode 23, Dewey sneaks into the Dark Joker base and tries to steal some of the Black Vaccine. Buros catches him, binds his arms and legs with vines, and proceeds to torture him with electricity. That's disturbing enough on his own, but during this whole confrontation, Buros is acting extremely creepy, and all the while, the usually blithe Dewey is begging him to stop. He talks about how he won't "abandon" Dewey (as he's raising his sword, laced with the power of the Black Vaccine), and then, as he's about to swing, he tells Dewey to "accept [his] last love." His last love. As in, there were more "loves" before this. Combined with Buros's behavior toward Dewey in certain other episodes, one must wonder exactly what happened. Keep in mind that Dewey is a child.
- The very end of the last episode shows that Ririka probably survived her sacrifice, which seems like a Surprisingly Happy Ending... However, one must remember that before she sacrificed herself, Ririka ordered Kanon to wipe everyone's memories of her. It's unknown if Kanon went through with it, but what if he did? Even if Ririka was alive, no one would remember her. She would have nowhere to go and no one to help her. On top of this, what would happen to Dewey? Ririka was the cause of his Heel–Face Turn, so would he even remember it?
