* ''Kodama-sensei''! The guy has some sort of unhingable jaw, and when he opens it wide (usually to yell at Keima for playing games in class) it turns into a portal through which an unending tunnel of Kodama heads can be seen screaming into infinity.
* Vintage executive Lune, introduced in Flag 152, where she's shown restraining her murderous impulses by stabbing herself instead of the one she wants to kill, and vowing that once New Hell is overthrown, she'll be sure to 'pay back' the ones who annoyed her. [[FridgeHorror Then you get a sense of why she has bandages covering various parts of her body,]] and are left wondering how many people she's made similar vows to before. All the while, [[MoodSwinger her emotions keep switching between]] [[TheStoic dead-eyed stoicism]], [[LaughingMad insane laughter]], and [[AxCrazy murderous frustration]].
** She's more scary in how she's the second really serious villain the series has had right after Fiore, who is extremely mild when compared to Lune.
*** Fiore herself. You wouldn't suspect that a clumsy looking {{Meganekko}} would willingly [[spoiler: jeopardize the bond between two sisters by tricking the elder one into thinking the younger one hates her, murder a schoolgirl because there is a goddess within her, and following the latter, almost succeed in killing a goddess]], and the reason she joined vintage and did all this? Because she dislikes New Hell's way and thinks a proper devil must be evil. Wow.
** And now Lune has managed to [[UpToEleven top herself]] in her fight against [[spoiler:Dokuro/Nikaido]], where ''both'' of them are [[NoHoldsBarredBeatdown as brutal with each other as possible]]--most notably is Lune's use of her magic knife to burrow throughout [[spoiler:Dokuro's]] body, and the latter [[spoiler:[[ImpaledWithExtremePrejudice brutally impaling]]]] Lune with [[spoiler:the device in the Akanemaru.]]
* Most of chapter 214, [[spoiler: with Keima, Elsie, and Dokuro stumbling across the bodies of the soldiers hired by Urara's grandfather, discovering said grandfather MISSING HIS LOWER BODY, suddenly being surrounded by a whole bunch of Vintage goons, complete with their creepy masks, and finally a grievously-wounded Dokuro delivering a NoHoldsBarredBeatdown to the lot of them. Messily.]]
* [[spoiler:[[BitchInSheepsClothing Kaori]]]], despite acting like a NiceGirl most of the time, or perhaps ''[[DissonantSerenity because]]'' of that. Something is just ''not right'' with that girl, if her violent and ''very'' abrupt {{Freak Out}}s are anything to go by.
* Satyr's weapon - A disgusting, insect like creature, comprised of shadow and darkness, which also happens to be [[spoiler: Elsie's true form]]
