Dialogue
- (Idle)
- Ukinami Yuzuha: Gotta seize the moment...
- Mischievous Boy: So much yummy food...
- (Talk to Yuzuha)
- Ukinami Yuzuha: Kama, when I give the signal, make your move - unzip his backpack and swap everything out, quick and slick, like always! You got this?!
- Ukinami Yuzuha: Mhm~ I knew I could count on you! That's my Kama, my most reliable partner!
Swap everything out?
What are you doing?- Ukinami Yuzuha: Ah, (WiseWise /
BelleBelle), it's you... Shh, keep it down, we can't let him notice us.
Who?
Why are you being so sneaky?- Ukinami Yuzuha: See that kid up ahead? The one skipping along? I'm tailing him... As for why, well, it's complicated...
- Ukinami Yuzuha: He is the last descendant of a ninja clan that has been hiding in New Eridu. Hunted by various factions for possessing rare treasures, it's up to us to free him from his tragic destiny...
That sounds... intense.
- Ukinami Yuzuha: Pfft, of course I'm messing with you! How could you fall for that? You're so adorable, (WiseWise /
BelleBelle)!
- Ukinami Yuzuha: Pfft, of course I'm messing with you! How could you fall for that? You're so adorable, (WiseWise /
You're messing with me again, are you?
- Ukinami Yuzuha: Why did you not fall for that? Have you built up immunity to my pranks? Hmm~ I can't have that! Life would be so dull if I can't tease you!
- Ukinami Yuzuha: Anyway, I'll explain later what we're doing. Come with me if you're curious~
- Ukinami Yuzuha: Lemme check my items... hmm, a cola bottle filled with herbal tea, ultra sour crybaby candy, and these weird magic mystery chocolate beans...
- Ukinami Yuzuha: Alright, we're all set. Kama, I choose you! Go!

"Ultimate Prank"
Story Description: You stumble into the middle of Yuzuha pranking someone... So this is what she means by the "Ultimate Prank"! You start to understand why she enjoys teasing people so much.
- Mischievous Boy: Hehe, school's out! Snack time! Let's see if this candy was worth waiting in line for~ *nom nom*
- Mischievous Boy: Eww! Super sour! My teeth feel like they're gonna fall out. Everyone said this candy was awesome. It's... yikes! Gotta get some cola to wash this down...
- Mischievous Boy: Blegh... This is totally bitter! What happened to my cola? It doesn't even taste like cola anymore! It's just... just like that gross herbal tea Mom makes me drink when I have a cold...
- Mischievous Boy: My mouth tastes yucky... Okay, this chocolate I bought with my saved-up pocket money should be safe, right? Here goes...
- Mischievous Boy: Wh—What is this!
It's like overcooked slugs mixed with strawberry jam and rotten eggs... Ewww!
That's pretty specific...
What a nasty taste...- (ProtagonistProtagonist): Uh, what's that smell? Could something that smells so weird and complicated even exist?
- Ukinami Yuzuha: Duh, it's the Prank Master's collection, obviously! Handcrafted by yours truly, Yuzuha! Don't worry, though. They're all made with natural ingredients. Super safe and harmless.
- Ukinami Yuzuha: ...Alright, let's head over now. Just act cool, like we're just strolling by.
Let's do it your way for now.
I'm dying to know what you're up to...- (ProtagonistProtagonist): (Okay, but what exactly are you trying to do? Hmm... whatever, I'll just go along with it. Given the current situation, I doubt I'll get much of an explanation anyway...Okay, but what exactly are you trying to do? Hmm... whatever, I'll just go along with it. Given the current situation, I doubt I'll get much of an explanation anyway... /
Okay... but what exactly are you doing? Hmm... never mind, I'll just go along with it. Based on how things are going, it doesn't seem like I'm gonna get an explanation anyway...Okay... but what exactly are you doing? Hmm... never mind, I'll just go along with it. Based on how things are going, it doesn't seem like I'm gonna get an explanation anyway...) - Mischievous Boy: *Sobbing* Who did this?! Who swapped my snacks for yucky stuff...
- Ukinami Yuzuha: Yo, kiddo, what's up? Why the long face? Wait a sec... Whatcha got there?...
- Ukinami Yuzuha: Whoa, you can't just be chowing down on that chocolate! Those choco beans you just ate... I mean, where'd you even get those...?
- Mischievous Boy: Y–You, who are you?! What's wrong with the thing in my hand? It–It's just a regular chocolate, right? Okay, maybe a bit expensive, but still pretty normal... Is there something wrong with it...?
- Ukinami Yuzuha: *Sigh* Kid... I get it now. Seems like some weird stuff's been going on with you lately... Like, crashing hard during lunch, blanking on easy questions in the quiz, and the biggest thing... your food's been tasting funky...
I can't even.
- (ProtagonistProtagonist): Never mind the last one, aren't the first two you mentioned pretty normal? Those happen all the time...
- Ukinami Yuzuha: Shh, I'm trying to figure out what's wrong with this kid. Don't distract me, (WiseWise /
BelleBelle)~
This is so weird!
- (ProtagonistProtagonist): Whoa! With all this weirdness, there's gotta be some kinda reason behind it, right?
- Ukinami Yuzuha: There's gotta be a reason... but ugh, it's way too embarrassing to say out loud...
- Mischievous Boy: Hey! Who are you?! How do you know so much about all this...? How'd you get everything right?
- Ukinami Yuzuha: You know what? Looks like the Prank God's got it out for you. Think back. Have you been messing with people, pulling pranks? Made anyone cry with your tricks?
- Mischievous Boy: I—I didn't mean to trick anyone... The Prank God's, like, a bad guy... right?
- Ukinami Yuzuha: The Prank God's not good or bad, it makes its own judgments. This chocolate is the Prank God's way of testing you. If you keep making people sad with your pranks, you're gonna get punished accordingly...
- Mischievous Boy: Th—The Prank God's... gonna punish me? What's gonna happen to me now?
- Ukinami Yuzuha: Like... the chocolate you ate might hatch into hundreds of slimy slugs inside your stomach—so many that they start oozing out of your mouth, until eventually, you turn into a giant slug yourself—
- Mischievous Boy: N—N—N—No way! You're just trying to scare me! How could someone turn into a slug!?
- Ukinami Yuzuha: Oh yeah? Don't believe me, huh? Check out the back of that chocolate wrapper, then. See how that totally normal chocolate suddenly has some weird symbol on it? That's the Prank God's signature right there!
- Mischievous Boy: Let me see! ...Y—Yeah, there's, like, a mark there...
- Ukinami Yuzuha: Also, doesn't your tummy feel all bloated and warm? Like... the slugs are already doing the wiggle worm inside...
- Mischievous Boy: Waaaaaah!! No way! I don't wanna turn into a slug-boy! What do I do? What do I do...? You know everything. You gotta know how to fix this, right? Please! Please! Help meeee...
That's terrifying!
Absolutely unbelievable!- (ProtagonistProtagonist): So, if you offend the Prank God, you turn into a slug? That's unbelievably insane, defies all logic, and is totally terrifying! Seriously, what are you gonna do now?
- Ukinami Yuzuha: Uh-huh, uh-huh~ Just like (brobro /
the ladythe lady) here said, the consequences are gonna be pretty nasty, you know? - Ukinami Yuzuha: But I got a fix for you. Just tell me what naughty things you've done, promise to turn over a new leaf, and I can sweet-talk the Prank God into forgiving you and getting rid of those slug eggs in your belly. After all, I'm the Prank Witch!
- Mischievous Boy: *Sobbing*... R—Really? If I tell you everything, then the Prank God will forgive me?
That's right.
You gotta trust the Prank Witch.- (ProtagonistProtagonist): Totally! See that fluffy little messenger behind the witch lady? That's the Prank God's mortal form.
- Mischievous Boy: Okay, okay... So, um, I kinda wanted to make friends with this girl... But I didn't know how to talk to her, so I did some not-so-nice stuff to get her to notice me...
- Ukinami Yuzuha: Did you, yank her hair, put bugs in her desk, and keep stealing her pens?
- Mischievous Boy: Y—Yeah! Sorry, Witch Lady... do you think the Prank God will forgive me now?
- Ukinami Yuzuha: OMG, no way! What a coincidence! That little girl you were messing with is actually my little sis, Sumire.
- Ukinami Yuzuha: She told me she really wanted to be friends with this guy, but he just kept picking on her. She came home crying for so long... Don't tell me that guy was you?
- Mischievous Boy: What! She cried? And for a long time?... I was just trying to get her to notice me...
- Mischievous Boy: I made her sad... so I guess I do deserve to turn into a slug... That's what I get...
- Ukinami Yuzuha: Hmm... but you probably won't have to turn into a slug anymore. I just got a message from the Prank God saying they'll let you off the hook this time. As long as you're willing to apologize to Sumire and be friends with her.
- Mischievous Boy: I—I totally will! I always wanted to be friends with her! I'm super sorry for playing those mean pranks on her...
- Ukinami Yuzuha: I heard from Sumire that your name's A-Xuan, right?
Hey, A-Xuan, as a Prank Witch, I'm gonna teach you a super secret prank playing trick, so listen up!
I'm intrigued!
It's gotta be a pro-tip!- (ProtagonistProtagonist): Whoa, a secret prank trick? Coming from the prank master Yuzuha herself? Definitely worth taking notes on!
- Ukinami Yuzuha: That is, pranks should never, ever cause real harm! You can prank someone you care about, but it should always lead to something good. After all, a joke's only funny if you can both laugh about it, right?
- A-Xuan: Th—That makes so much sense. So that's the secret to pranking... You know so much about pranks! I wanna hear more! Please, Witch Lady, teach me your secrets!
- Ukinami Yuzuha: Okay... so, truth be told, even though I'm a Prank Witch, I'm not that great at pulling pranks myself. All those wise words I was dropping? I learned them from this awesome (brobro /
ladylady) right here.
What?!
How?!- (ProtagonistProtagonist): Wait, what...? Learned from me? I don't remember any of this! Hold up... I'm sensing a trap...
- Just as you're about to deny it, the girl flashes you a mischievous smile.
Her lips form the words, "Leaving it to you now." - A-Xuan: Wow! The Witch Lady says you're powerful. Could you teach me something?
Oh no...
Yuzuha is running away...- (ProtagonistProtagonist): (Wait... Yuzuha, Yuzuha! I'm terrible with kids like this... Damn, she totally played me... again!Wait... Yuzuha, Yuzuha! I'm terrible with kids like this... Damn, she totally played me... again! /
Hey, Yuzuha! Seriously?! You're ditching me and running off like that?!... *Sobbing* I can't believe you got me again...!Hey, Yuzuha! Seriously?! You're ditching me and running off like that?!... *Sobbing* I can't believe you got me again...!)

- Ukinami Yuzuha: So? Did you finish chatting with A-Xuan?
- Ukinami Yuzuha: Thanks a bunch~ Everything's sorted out, little Sumire shouldn't be feeling down anymore.
Why did you run away...
You're so mean, Yuzuha...- Ukinami Yuzuha: Hehe, I just thought things would go more smoothly if I left it to you~
- Ukinami Yuzuha: Sumire was so upset she couldn't even eat... Now the two of them should finally make up.
I'm glad...
I feel like I understand you better now.- Ukinami Yuzuha: Whoa, don't say stuff like that with such a serious tone~ You're making my heart go thump-thump non-stop!
