* Gundam. Looks, sounds and speaks like an evil warlord, what is his Super High School Level?... Animal Training, his current pets being 4 cute hamsters. And the hamsters are [[DeathbringerTheAdorable called]] The Four Dark Deva Lords of Destruction!
* The conversation that results from Fatogami's attempts at unifying the group.
--> '''Fatogami:''' If we wish to live through this extraordinary ordeal, what do you think is of the utmost importance right now?
--> '''Akane:''' ...Of the utmost importance? You don't mean food and sleep, do you?
--> '''Nidai:''' Ku... you're forgetting bowel movements. EAT WELL, SLEEP WELL, ''SHIT'' WELL!
* A number of the characters have rather ridiculous expression or faces that betray your thoughts on them.
** Kuzuryuu, a baby faced, small, rosy-cheeked Super High School Level Gangster!
** Nanami's sleepy face.
*** As well as her "offended" face.
** Ibuki Mioda's pinnochio-like "oni" face.
** Monobear's [[http://lpix.org/1344244/096-mb.png super-muscular transformation]].
* Komaeda monologuing at the beginning of chapter 2, only to be interrupted by someone shouting [[BigShutUp "SHUT UUUUUUUUUP!!"]] and a crashing sound.
* Souda gets himself and Hinata invited to the girls beach party hoping to see Sonia in a bikini. Cue Sonia showing up in a wetsuit.
* The group's general reaction to Ibuki Mioda's singing performance.
** Souda's face specifically.
** Or the fact that Hiyoko is the only one who enjoys it.
* The roller coaster ride.
** The fact that Souda pretty much had to be forced onto the roller coaster by the rest of the group.
** Souda and Gundam's expressions during the roller coaster ride.
* [[spoiler: Sonia's reaction to [=RoboNidai=].]]
** [[spoiler: Souda's reaction is pretty hilarious as well. He's a little too enthusiastic when he asks Nidai if he could take him apart so he could study him. And both times when Nidai claims he has a new ability, Souda's first question is "Is it flying?"]]
* [[spoiler: [=RoboNidai=] and his ability to create beverages from his eyes.]]
** [[spoiler: And his enthusiasm in offering Hinata a drink]]
* Gundam calling Souda a virgin.
** Sonia revealing she isn't.
*** And the fact that she's only disappointed because it means she can't go to an amusement park in Hell with Gundam.
* Sonia Nevermind speaking like a formal princess, exactly as you'd expect...and then randomly throwing "hella", "tomfoolery", or "you betcha" into the mix or making references to outdated Japanese popular culture.
* "Fat Togami"'s Free Time events, in which Togami talks in perfect seriousness about body mass indexes or deciding which meat is better than the other.
* During the first trial, [[spoiler:Komaeda]] reveals his intentions, leading to this gem:
-->'''Ibuki:''' Oh no! This guy is definitely the type who killed animals in his neighborhood when he was a kid!
-->'''Sonia:''' The type who watches "Friday the 13th" with a gleam in his eyes... [[NightmareFetishist Just like me]].
* One more for the count:
-->'''Akane:''' What's an 'aspersion'? Does it taste good?
-->'''Hiyoko:''' Asbestos is also excellent, you know. You should try some, later.
* [[spoiler: Hanamura's breakdown]] at the end of trial one; he devolves into completely unintelligible rural gibberish which somehow ends with him screaming AVRIL LAVIGNE! (As the cherry on top, Monomi - who has been translating for the other students - dutifully parrots this last line even though everyone could hear it.)
** To put this one in context, Avril Lavigne is a popular Canadian singer-songwriter. She has absolutely ''nothing to do with'' [[spoiler: Hanamura]]'s profession as a [[spoiler: chef]]; her name is just dropped out of nowhere to show how crazy [[spoiler: Hanamura]] has become.
* After the end of the first chapter, Komaeda goes on this really hokey spiel about hope [[spoiler: after having led Hanamura and Togami to their deaths.]] Akane offers to punch him, but Hinata tells her to lay off and ignore him. Not a minute later, and...
-->'''Komaeda''': You don't even remember your own talent...
-->'''Hinata''': ...Owari, go ahead and punch him.
* Tanaka, true to form, offers a line that's both [[SugarWiki/MomentOfAwesome magnificent]] and hysterical:
-->'''Gundam:''' Monobear. I will listen to your jests later, as I smoke a cigar standing over your ''corpse''.
* Later on, Akane complains about how all of the killers are getting their supplies from the same place:
-->'''Akane:''' The Mart, again...? That place is pretty much the one-stop-shop for all your criminal needs, huh.
* In Komaeda's first Free Time event, he helps Hinata figure out his talent by suggesting some, which include Super High School Level Therapist, [[AmnesiacHero Amnesiac]], Eccentric, and [[AnimeHair Spiky Hair]].
* In Chapter 4, Sonia, [[spoiler: who hasn't eaten due to Monobear's sick game of locking them in a tower without food unless someone is murdered]] starts seeing her friends' faces as ''cake'' and even asks, as politely as always, if she could eat a part of them.
-->'''Sonia''': Oh my, Mr. Hinata…Now that I’ve taken a closer look, your face is a Sachertorte! May I take a portion of the center? I’ll make sure to return it to you later!
--> '''Hinata''': Sonia…Seriously...Get ahold of yourself…
* In chapter four, the gang splits up several times to explore the new island; each time, Souda declares that he'll be going with Sonia, only for someone else to inform him that she already left with Gundam.
* In chapter five, [[spoiler: the group is debating whether or not Komaeda would have died instantaneously from his spear wound]]:
--> '''Sonia''': [[InnocentInnuendo You could not last very long with such a large, thick object inside of you!]]
--> '''Souda''': ...C-Could you say that again, please?
--> '''Sonia''': As I said, you could not last very long with such a large, thick object inside of you!
--> '''Souda (blushing)''': Could you say it one more time, so I could record you...?
