* ArchiveBinge: It's very tempting to tear through all fifty-plus chapters of Kagerou in a single weekend.
* ArchivePanic: When the archive page keeps expanding to show the over 45 chapters with 850+ pages, it can definitely get a little intimidating.
* CreepyAwesome: Dark. Terrifying. But he's adorable! But, ''brrr''...
* DracoInLeatherPants: If Red weren't [[{{Bishonen}} so pretty]], we'd hate him a lot more.
* EpilepticTrees: A story this convoluted just invites them. (But still.)
* EvilIsSexy: Red. ''Dear God,'' Red.
** And while some Kagerou evil is disturbingly UncannyValley, some is [[http://electric-manga.com/49/09.html Tcaolin]].
* SugarWiki/FunnyMoments: Heyoka to Kano: "Oho! I get it now, we're playing the angsty teen! Lemme play too! Can I be the sexual deviant?"
** "You're not a Republican!" "I don't think so, no."
* GeniusBonus: Every twenty-third page of a chapter in ''Kagerou'' has "SKIDOO!" at the top of the page, a reference to the phrase "twenty-three skidoo," obsolete slang from early 1900s America. It sort of meant...skedaddle.
** It is useful for a reader to know that "5150" (fifty-one-fifty) is a section of the California Welfare and Institutions Code which refers to involuntary psychiatric hold. That is to say, restraining a psychiatric patient without their consent, because that patient is deemed a danger to themselves or others due to their condition.
* SugarWiki/{{Heartwarming Moment|s}}: [[spoiler: Kano's impulsive, awkward, adorable hand-on-the-shoulder-comfort moment with Cho. It's especially heartwarming because Kano ''despises'' [[HatesBeingTouched physical contact]].]]
* SugarWiki/MomentOfAwesome: Red gets one when he kills Monster. It's also a Moment of Creepy.
-->'''Monster'''''(currently being choked by Red's hair)'': Aren't... you... the Champion?
-->'''Red:''' Sure. What's your point?
-->'''Monster:''' You're... supposed to be... the GOOD guy!
-->'''Red:''' Oh. I'll keep that in mind.
-->''He snaps her neck.''
** Kano receives one all his own a little later in his mindscape: [[spoiler:he snaps out of his HeroicBSOD just in time to stop Red from raping Fuuka, which he accomplishes by beating Red half to death (...again) with a tire iron.]]
** Tonbo, who before then had been a DamselInDistress, telling Tcaolin exactly where to shove it after getting her speech back:
--->[[http://www.electric-manga.com/26/16.html G-Go f-fuck yourself... M-My lady.]]
** Dark has one in the form of [[spoiler: setting Red on fire after making him read the names of every person he had ever killed. And then stabbing him with giant fiery fingers]].
* NightmareFuel: Anything that happens in Kano's head qualifies. The horrible tentacle creatures? Hung from the ceiling with pipes through his chest? The Breaking Noise Monster? Yeesh.
* OneSceneWonder: Father Kwellar.
* TheWoobie: All of the main characters take a turn as TheWoobie, but Kano, Kid, and Tonbo/Fuuka come out on top.
** Dark blows them all out of the water.
