All spoilers are unmarked!
- In the NISA translation, Usami describes their location by the seaside as "Out where it's better! Out where it's wetter! Out by the sea!"
- Additionally, one of the Steam achievements for this game is called "Look At This Stuff, Isn't It Neat?".
- At one point Monokuma seems to use Heaven's Door on Monomi, as well as the Pegasus Meteor Fist later on.
- Later than that, he uses the Kuzuryūsen from Rurouni Kenshin on her, although each light ball spells out "I ♥ pudding delicious".
- Fuyuhiko's introduction ends with him telling Hajime and Nagito to make like a tree and fuck off.
- The hidden coconut event in the first chapter has Peko slice a coconut open for her classmates. Afterward, she laments that once again, she's cut a worthless object.
- During the first trial, Monokuma says it's okay if the other characters fight, as long as it doesn't escalate into a "burly brawl".
- When Monokuma reveals "Twilight Syndrome Murder Case" in chapter 2, Hiyoko says she would rather play games about "riddle-solving professors or collecting cute monsters".
- Gundham's insistence that his pet hamsters are actually shape-shifting "Dark Devas of Destruction" may be a reference to how in the Blue Exorcist anime Amaimon, the Demon King of Earth, used the form of a hamster as his Sleep-Mode Size.
- When Teruteru wonders if Byakuya and Peko used the blackout to make out in the bathroom, he says it would be "Truly, truly outrageous."
- Mahiru Koizumi is an intrepid photographer who dies rather early in the story. Sentai fans should notice another short-lived photographer whose last name is also Koizumi.
- In her first Free Time event, Chiaki mentions Trio the Punch, the Trope Codifier for the "kuso-ge" genre.
- During her second Free Time event, Chiaki directly references Shadowgate and asks Hajime why he didn't get it. Though she references the Japanese version, rather than the original American version, saying "My adventure ended like this", rather than the original "It's a sad thing that your adventures have ended here!!" that US players would be aware of.
- Also during her second event, if Hajime suggests going to the park, Chiaki will mention "a game you're only able to play in the sun", while suggesting the supermarket will prompt her to say that she enjoys running over zombies with skateboards and wheelchairs.
- In the second trial, Ibuki shows she's a fan of Public Enemy (and/or, given her most recent Genre Shift, Anthrax) when she says "Vase?! How Low
Can You Go?!" - In the second trial, if Hajime says that Monokuma was Girl D in Twilight Syndrome Murder Mystery (the one who took the photos), he jokingly agrees and tells the students to say "fuzzy pickles!"
- When Hajime reveals the murder weapon of Twilight Syndrome Murder Mystery (gravel wrapped in a school swimsuit) Ibuki says that it's an idea that would astonish even the ace attorney.
- In the Japanese version, Peko's execution is called Abarenbou Shoujo ("Unfettered Girl"), a reference to the Japanese drama Abarenbou Shogun.
- The "Titty Typhoon" building and its design is a reference to From Dusk Till Dawn's "Titty Twister" bar.
- During one of her free time events, Ibuki practices with Hajime while saying "Da boom na da mmm dum na ema".
- If Hajime accuses Chiaki in Chapter 3, she says "...Hey, hey...this isn't Portopia, so a development like this is really out of place..."
- When stricken with the Despair Disease, Nagito eventually starts making repeated references to Australian pop duo The Veronicas.
- He also mentions that since Ibuki is actually a pair of twins, there are 17 people on the island.
- During his execution, Gundham attempts to escape his fate by using his magic circle in a very familiar way.
- In the translation, Ibuki is thirty-one flavors of stoked for all the deliciousness at the supermarket. Too bad there doesn't seem to be an actual Baskin-Robbins there, though.
- In the translation, during Nekomaru's introduction, Nagito makes an off-handed reference to how Nekomaru led a rugby team of delinquents to victory, among other accomplishments. Later on, Monokuma deliberately mistakes Nekomaru for Ranma Saotome.
- The translation also adds a bit of Waxing Lyrical when Kazuichi tells Hajime how he's "never gonna give her up" in regards to Sonia. Hajime's immediate response is to mention how he might let her down though.
- More Waxing Lyrical, this time from Monokuma: When the Despair Disease strikes, he says that not everyone's down with the sickness... at least not yet.
- Even more Waxing Lyrical from Kazuichi: He winds up quoting the chorus from "Complicated"◊ by... Avril Lavigne.
- And some more! If the player visits the military base during the Dangan Island mode, before asking him if he's excited, he'll exclaim, "This shit is bananas!"
- Kazuichi does it again in the fourth trial: "I'll definitely make her watch me! I'm gonna stand out till she notices me!"
- In chapter 2, when Akane comes into the diner covered in blood (after a sparring match with Nekomaru), Ibuki says, "I-It wouldn't be strange if we nicknamed you Carrie right now!"
- Another one from the translation: Kazuichi refuses to believe in the Future Foundation because this 'isn't a comic book.'
- At one point, Nekomaru proclaims himself to be a Time Lord. Ironically, at that point, he looks more like a Cyberman.
- Chapter 4 is titled "Do Ultimate Robots Dream of Clockwork?" The title of Chapter 2, "Sea and Punishment, Sin and Coconuts" could be a reference to the video game Sin and Punishment.
- During her and Nekomaru's fight, Akane's Kiai is "MUDADADADADADADADADADADADADA!" Likewise, one of Monokuma's many battle cries is "ORAORAORAORA!"
- During a trial intermission, Monokuma name-drops the Jet Stream Attack when discussing the newest insult he came up for Monomi.
- "Hajime used Call Sonia. But nothing happened."
- In the Chapter 4 trial, Monokuma threatens to "gently caress" Monomi.
- Gundham Tanaka warns that you wouldn't like him when he's angry.
- There's posters in the movie theater and Chiaki's room for Danganronpa Another Episode: Ultra Despair Girls in the place of the Time Travelers posters seen in the PSP version. Time Travelers still has an item based on its terrorist group "Skull" in both versions, which is one of Chiaki's favorite items, and has some Danganronpa shout-outs appear in that game as a form of cross promotion.
- From the NISA translation, one of the descriptions of the giant Cola bottles referrers to them too big for a Titan, but an Aberrant might be able to finish one.
- One of Gundham Tanaka's "objection" phrases is "Jagan no chikara wo nameruna/Don't underestimate the power of the evil eye", which is a catchphrase of Hiei from YuYu Hakusho.
- Akane Owari makes a good number of Dragon Ball references, including shout outs to lyrics from Makafushigi Adventure and CHA-LA HEAD-CHA-LA, a number of lines which are almost direct quotes from Son Goku and in Island Mode she even makes rather blatant comments which are obvious references to Karin Tower and Piccolo Daimaou.
- Nekomaru's Heroic Sacrifice to save her from Monokuma in Chapter 3 is inspired by Piccolo's sacrifice to save Gohan, including repeating his Dying Speech.
Nekomaru: The time I spent with you...wasn't so bad. Don't...die...Akane...- During Sonia's Island Mode ending, you can say "Mafuba" instead of "Makango" and she talks about sealing away evil.
- During the conclusion of the fifth chapter, the glitched text for Chiaki's door quotes the Konami Code.
- Chiaki thinks that the big building in the final island is too dangerous to investigate by herself and says "It's dangerous to go alone". That lead to some players to say "Take this!"
- Early in the sixth chapter:Monokuma: "Oh my! Are your minds getting the grumblies that only knowledge can satisfy?"
- The world has entered a new age of darkness? Build a Future Foundation.
- When Hajime initially refuses to watch Monokuma's Wizard of Monomi (2.5D) movie, the bear says Hajime's decision "makes [him] a saaaaaaad Monokuma..."
- The Morse Code in one of the Monokuma Theaters translates to "Be sure to drink your Kumatine."
- The amusement park on the Fourth Island is an obvious reference to the Disney Theme Parks.
- Nezumi Castlenote is a large, mouse-themed castle (as Hajime says, "There's a lot of things I could say about this building, but it's probably better if I say nothing at all", and Monokuma and Monomi reveal that they're both terrified of micenote ) in the vein of the princess castles featured at each park.
- The Funhouse's facade is based on It's a Small World.
- The roller coaster's facade appears to be based on Space Mountain.
- Possibly inadvertent, but in case 5, Akane's repeated references to Nagito's "male tail" are translated as "front tail".
- After the discovery of the victim in Chapter 5, upon examining the bloody Monokuma plushie, Monokuma himself proclaims "No response... He's dead, Jim.".
- During chapter 6 Monokuma makes a reference to the One-Winged Angel trope.Monokuma: A transformation is customary in a final boss battle, right? You know, like that one role-playing game. You know what game I'm talking about. Final...note
Kazuichi: D-don't say it! - The AI Junko, in a discussion about her size, mentions that "most action game bosses are much bigger", specifically mentioning God of War (another PlayStation exclusive). In the NISA translation, she initially makes a reference to a different video game series by saying "Final...", only to be interrupted by Kazuichi who screams "Don't say it!". Eventually, she finally says the name of the game she's talking about, which is "Knifearella". Fuyuhiko is shocked that she actually said it.
- One of her P.T.A. lines is "A miracle won't happen!".
- She also makes references to mystery stories where the detective investigating the killings turns out to be the killer, calling such games contrived and cliched.
- Sonia's last name (Nevermind) and country of origin (Novoselic) are references to Nirvana. Supplementary material also reveals she attended In Utero High School.
- Questions during Logic Dive appear in six-sided boxes reminiscent of Who Wants to Be a Millionaire?.
- One of the presents you can get is called Falkor's Muffler.
- Another present is the "Kiss Note." Then there's the serial killer Sparkling Justice (Kirakira-chan), who targets other criminals. In addition, Kazuichi makes an offhanded reference to the Death Note itself as something as patently implausible as high schoolers destroying the world.
- Another one is the "Power Gauntlet," which looks just like the NES Power Glove. Its description even says "Die-hard fans love how "bad" this thing is."
- One of the presents called "Mr. Stapler" an ordinary stapler that has use in the medical field and easily close wounds.
- The Hakagura Crystal Ball present has both a Call-Back and a Shout-Out in its description: "Thirty percent of the time, it works 100 percent of the time."
- One that was partially lost in localization was "Humanity and Honor Without Battle," a series of critically-acclaimed yakuza films in which no actual violence takes place, which originally had an item that was misnamed "Another Battle" and instead references the franchise as "Honor and Humanity", the title of the achievement for getting all of Kuzuryu's hope shards.
- Ibuki's full name and talent is a reference to K-On!, with the kanji from her name being taken from the names of the four main characters.note
- She shares a birthday with protagonist Yui Hirasawa.
- The "Apron Dress" being one of the best presents to give Ibuki is also a reference to K-On!. At one point, the main characters all dress in maid outfits to bolster their popularity. She also mentions eating strawberry shortcake every single day in the first investigation just like the girls of the light-music club do, which Komaeda thinks sounds a little excessive (this was dropped in the official translation to give her a taste for fried rice with gravy).
- The translation continues the tradition set up by the trophies of the previous game.
- The one for getting every other trophy in the game is Hope's Last Reward.
- Twogami's new trophy is The game hungers for seconds... And thirds.
- Nekomaru's is Caught in a Rad Bromance.
- Nagito's is Hope Springs Eternal.
- Fuyuhiko's is Honor and Humanity.
- Mikan's is Helloooooooooooooooo Nurse!
- Finishing Chapter 3 (during which she's executed) is Is It Medicine or Social Skill?
- Raising every type of e-pet is Gotta Raise 'Em All.
- Getting 50 unique presents is Look at This Stuff, Isn't it Neat?
- Destroying 500 white noise lines is The Airborne Static Event.
- During the first trial, Teruteru tries to prove he's not guilty by saying you can tell that a person is lying by licking their sweat.
- The last of Famous Monokuma Quotes is "Why are you taking this game so seriously?" This is a reference to The Stinger of the infamous kuso-ge Takeshi's Challenge, which asked the same question to those who waited minutes on the ending screen of a game that existed solely to torment the player.
- The Hidden Monokumas in Chapter 5 are wearing a device resembling the COMPs from the early Shin Megami Tensei games, with their pose resembling a flipped version of the official art for the first game's protagonist post-Time Skip.
- The Clock Up ability, which increases the max speed during Logic Dive segments, is a reference to the technique of the same name from Kamen Rider Kabuto that allows the user to reach the speed of light.
- If the time limit runs out when looking for the killer's hiding spot in Chapter 2, Chiaki remarks about how "even F-Zeros run hot during Time Attack."
- Nekomaru's reaction to seeing the door in Strawberry Hall is I wonder what that means... It's funny, it's spelled just like the word, "open"!
