Some of the minds you read are pretty funny, particularly a skater lamenting screwing up a move, and consoling himself that he only needs one of those to have kids.
Uzuki challenges Neku and Beat to a game of "Reaper Sport 4", but Beat doesn't know what it is, and they just kind of wander around until Uzuki gets frustrated and demands to know why they aren't playing tag seriously (Beat: "So, Reaper Sport 4 is..." Uzuki: "It's TAG, you dolt!"). Then while she's in the midst of her rant, Neku just quietly walks up to her and: "Tag. You're it."
"Take this!" "Dumbass!" "Come back when you grow a pair." The latter sounds even funnier if Beat says it after defeating Tigris Cantus.
"It's a party in my mouth!"
Not to mention the Tin-Pin Slammer sidequest in 'Another Day', complete with Neku's 'emo urges', and Sho Minamimoto being the son of Ken Doi, the Ramen Shop owner!
And in that segment, they remark that there are freaky sounds in the megaphone someone left behind. They play it, and it's of Sho Minamimoto shouting "Sine! Cosine! TANGENT!"
Neku referring to the whole thing as "the detour from hell."
The more you buy from stores, the more the store owners like you. Every store owner, from Ken Doi to Mr. H, become increasingly friendly towards you, as they appreciate Neku's continued patronage. Every store owner, that is, except Mick, the recurring NPC who runs Shadow Ramen in Dogenzaka. When you purchase enough Shadow Steak Ramen, you'll discover that Mick is absolutely petrified of the prospect of Neku having a crush on him. Enter the shop and leave without buying anything, and you'll see.
Better yet. Although all the store owners are genuinely pleased for buying too much of their products on sale, they put up happy looks and are very excited to see Neku entering. Makoto's look is the opposite of that, which is this: (O_O).
The little conversation that takes place when Kitaniji first introduces Higashizawa to the rest of the Reapers.
Minamimoto: Hey, Megs— Who’s the bulldozer?
Kitaniji: Meet Higashizawa— this session’s Game Master. He’ll be handling my affairs in my stead.
Higashizawa: You do me a great honor, sir. Watch! I will turn this week’s fracas into a fricassee!
Minamimoto: You planning to erase them, or EAT them?
After Joshua's rant about Shibuya and how they're walking through a place of history and literature Neku's deadpan response of "I feel so epic." was rather hilarious.
The fact that Sho Minamimoto's HP is 3141. Even better: his HP in taboo form is 5926. In case you didn't get it, they're the digits of pi.
The NPCs' thoughts are occasionally amusing, but this one takes the cake.
Uhh, I'm not good with crowds...
Crowds bring out those symbols–the weebers!
I can see them everywhere!
There! Clinging to that guy's back–WEEBERS! Weebie weebie weebie...
There's also this.
I thought I saw someone with wings the other day...
No more caffeine.
Another goes something like "HEY, YOU. Yeah, you. Stop reading my mind."
A bit of a variation; a few NPCs can think something along the lines of "What are you doing reading my mind? If you think you can mind control me, you've got another thing coming!" It was probably foreshadowing, but it's highly amusing to see the same sprite a few chapters later thinking decidedly differently.
When Kariya catches Joshua using his innate power, he criticizes him for a bit before letting him off with a warning.
So let's just say I blinked. Not next time, though. You'll be erased before you know it.
Some of your partner's reactions when you run away from a fight:
Joshua: Oh, we're running? You didn't seem the type.
Joshua: Well, I suppose it's inevitable...sometimes. Hee hee...
Neku: I suppose you're an ass. All the time.
Worst is when you do it too many times in a row and Josh... says... nothing. That creeps Neku out more than anything else in the entire game.
What was quoted above is what happens after you run away just once or twice. When Joshua's starting to get annoyed, he starts grinding Neku's nerves a little bit more. When Neku complains about that, Joshua swears not to say another word on the matter...hence his silence when he's really annoyed. He's being even more of aJerk Assthan he usually is.
His annoyance at showing 777 the wrong phone-past-photo is at least worth a smile, too.
This gem from around the middle of Joshua's week: "Har har, you're killing me, Josh. Oh wait..."
Uzuki's continued annoyance at not being able to do anything in Week Two. The Tin Pin match is particularly memorable.
Later, the "tag game" with her in Week Three. Uzuki's Hair-Trigger Temper is always a reliable source of humor.
"New mission! Defeat the pissed off reaper!"
Neku answering his phone at some point. "Hello. Dead kid talking."
Neku and Beat are together, and Beat's idiocy starts getting on Neku's nerves.
Neku and Joshua playing Tin Pin Slammer in the beginning of the fourth day, what really kicks is Neku doing a pose very similar to Joshua after he won and keep in mind that's the only time he used that pose. 2nd one on the bottom.
If you scan the NPCs' thoughts, the one labelled "Clones?" will earn you the following message:
So then, CAT's this group of twenty different creators... all with the same face?
Makes sense... I think?
Is that even possible?
Funny enough on its own, but when you play Another Day and get the Secret Reports, you find out that this is in fact entirely possible, because Hanekoma, being an Angel, is able to visit alternate universe versions of himself - who's to say he never had 19 other selves help him out for a bit?
It is kind of an Accidental Pun (only because we know Beat), but Beat calls Kariya "Lollipop" and keeps bringing up "Licking" (fighting) Kariya.
On a meta level, some of the fan abridged series are pretty hilarious:
