Name	Text
Shauna	Playing a game with everyone... This'll make a wonderful memory! ♪
Steven	I'm the detective... I've been interested in detectives for a while, actually.
Shauna	I think it suits you, Steven!
Steven	Heh. I won't let you down!

• The Mystery Game Begins!

Name	Text
Lear	Sync pairs of Pasio! I'm happy to announce that we'll be holding an interactive mystery game! Play a role and solve the mansion's mysteries! IF you can solve them! Hahahahaha!
(The lights turn on, revealing that Lear is standing in his villa with a group of people around him)
Lear	And that's what's going on!
(Lyra, Burgh, Shauna, Looker, Melony, Guzma, Steven, and Agatha are gathered around Lear)
Steven	So we've been invited as playtesters?
Lear	Precisely. I will have you all act the roles you're given and play this mystery-solving game. Among the roles you will play, there is a culprit who will cause an incident...who is obviously hiding their identity. You will be asked to figure out who the culprit is and what kind of incident happened.
Shauna	Wow! That sounds like so much fun! ♪
Lear	Now then, draw to decide your roles!

• Roles Are Decided!

Name	Text
(Villa; Lear and the others are all standing around chatting; Steven and Shauna appear, wearing their special costumes)
Lyra	Wow! You two get costumes? That's nice!
Shauna	Heehee! Does it suit me? Apparently, I'm the detective's assistant!
Steven	And I'm the detective. They're really putting a lot of effort into this event, preparing costumes and all.
Shauna	I'll do my best to support you as detective's assistant!
Steven	Great! I'll be counting on you!
Burgh	I'm the musician... Are there no costumes for us?
Lear	We don't have all the costumes yet, as we're still in the testing phase.
Lyra	Awww... I would have liked to wear the artist's costume.
Looker	I can't believe I don't get to be the detective. It would have been perfect for me...
Agatha	But the main idea of the game is that you can still make deductions even if you're not the detective, right? Why don't you just guess the culprit before the detective does?
Looker	I suppose you're right... Then I'll stick with my role as the gardener! By the way, what's your role, Agatha?
Agatha	I'm the owner of the mansion. Why, am I a suspect already?
Guzma	I'm the cleaner?! There's no need for cleaning if you just smash everything to bits!
Melony	I'm the sculptor... Don't you go breaking any of my art, now.
Lear	Does everyone know what role they'll be playing?
(Everyone nods)
Lear	Now, before we begin the game, let me go over some simple rules. Each participant has been given a role, and one of those roles is the culprit! However, the culprit has also been given an additional role to serve as a decoy. The culprit must use their decoy role to avoid suspicion while causing "the incident."
Steven	And everyone else should play their roles and try to guess who the culprit is, right?
Lear	Indeed. To discover the culprit, it's important to figure out what happened in this mansion. Piecing together what occurred is crucial to solving the mystery!
Shauna	I have a question! Can you get help from your partner Pokémon during the game?
Lear	That's fine. The point of this game is to enjoy it as a sync pair. Do you understand the rules? If so, let the games begin!
(Transition to another room in the villa; Steven is talking to his Stoutland)
Steven	It seems everyone's acting out their roles. Now, as the detective, this says I should... Go around the mansion and observe the other participants. To the culprit, I'm just an annoying snoop.

• Explore the Mansion!

Name	Text
(Forest; Looker and Agatha are talking to a Bulbasaur, Oddish, and Hoppip; Steven approaches them)
Agatha	Oh, hey, Mr. Detective. Are you wandering around because you're bored?
Steven	Haha! Well, this IS my job... Agatha, you're the owner of the mansion, right?
Agatha	That's right. You should show me some respect.
Looker	And I'm the gardener!
Steven	What were you two doing just now?
Looker	We were talking about the Pokémon in the garden!
Agatha	He was explaining a few things to me regarding the Pokémon that live in the garden.
(The Bulbasaur, Oddish, and Hoppip cry out)
Steven	Could you clarify what you mean?
Agatha	This mansion wasn't originally mine.
(The background music stops, and a mysterious tone plays)
Agatha	It was seized from a distinguished family to clear a debt.
(The background music resumes)
Looker	So the Pokémon in the garden are from that family.
Steven	Which means you've only recently started living here?
Agatha	That's right.
???	Hey, Steven. ♪
(Shauna walks up)
Shauna	I'm here to help you as the detective's assistant! I had a look around the mansion, and I memorized the rooms! ♪
Steven	That's amazing! Could you show me around?
Shauna	Leave it to me. ♪
Steven	Well then, see you two later!
(Looker and Agatha wave as Steven and Shauna leave; transition to a room indoors)
Shauna	Here, this is the art studio!
(Shauna and Steven approach Melony and Lapras)
Shauna	Oh, wow! You're making a sculpture out of ice! ♪
Melony	Ahaha! Fitting for a sculptor, right? Be careful not to slip on the leftover shards!
Shauna	OK!
(Shauna wanders off while Steven talks to Melony; the background music stops, and a mysterious tone plays)
Melony	By the way, I heard there's treasure somewhere in this mansion.
(The background music resumes)
Melony	And I might be interested in that treasure...
Steven	I see...
(Transition to a room lined with lockers)
Shauna	Next is the storage room!
(Steven and Shauna approach Guzma and Golisopod)
Guzma	Tch! Why do I have to be the one cleaning?
Shauna	You don't like your role, Guzma?
(The background music stops, and a mysterious tone plays)
Guzma	Well, duh. Also, the cleaner supposedly doesn't like the owner of the mansion.
(The background music resumes)
Guzma	If that's the deal, then I don't need to waste my time acting. I can just keep complaining, since it fits the part.
Steven	You're right. Acting might be your calling!
Guzma	Sh-shut it! I'm busy right now! Go away!
(Transition to a balcony overlooking a courtyard)
Shauna	This place has a beautiful view. ♪
(Shauna notices Burgh and Lyra chatting, so she and Steven approach them)
Shauna	Is the artist duo having a chat?
Lyra	Yep! We were just talking about how it would have been great if our roles were swapped! I'm the artist...
Burgh	And I'm the musician.
Steven	I'm just going around talking to everyone right now. Have you noticed anything out of the ordinary?
Lyra	Umm... Oh yeah! I was supposed to say something specific to anyone who asked a question!
Burgh	Hmm... Are you supposed to tell them that?
Lyra	What? Is that against the rules?
Burgh	No, you're not breaking the rules. But if you're the culprit, what you just said would be extremely disadvantageous for you...
Lyra	B-but if I don't say anything now, that's even more suspicious, right? So, in this mansion, there's an old painting of a little girl. And as an artist, I was drawn to that painting! Errr, supposedly.
(The background music stops, and a mysterious tone plays)
Burgh	So that means it's a painting of Agatha, the owner of the mansion?
(The background music resumes)
Lyra	Maybe...
Steven	... ... ...
(Someone yells in the distance; a door opens, and Looker and Agatha run into the room)
Looker	C'est une catastrophe! The mansion's treasure has been stolen!
(Steven and Shauna look shocked)

• An Incident Occurs!

Name	Text
A treasure was stolen from the locked treasure vault! The participants shared the information they had and organized their thoughts on the situation...
Steven	Looker and Agatha have been together since the beginning of the game. So have Lyra and Burgh. Since there's only one culprit, those four have alibis.
Lyra	What's an alibi?
Steven	It means you can prove that you weren't at the crime scene when the incident occurred.
Shauna	Right, so the four of them can vouch for each other! Which means there're two suspects—Guzma and Melony?!
Steven	There're four if you include me and Shauna. We met up at one point, but before that, we were working separately.
Shauna	Oh, that's right! So, who's the most suspicious out of the four right now?
(Everyone looks at Guzma)
Guzma	A-are you saying I'm the culprit?! I haven't been in no treasure vault! I have the keys to some of the rooms so I can clean, but I don't have the key to the treasure vault!
Agatha	Guzma's telling the truth. I have the key. See? Here it is. As the owner of the mansion, I have all the keys.
(Steven looks at Shauna's Klefki, who doesn't react)
Steven	Are those really all of your keys, Agatha?
Agatha	They should be. Why?
Steven	I see...
Shauna	If Agatha had the keys, no one else can get into the room, right?
Steven	I think we need to investigate a bit more...
(Shauna leads Steven to a room with a dark brown floor)
Shauna	This is the treasure vault!
Steven	We've got to look for a clue...
(Steven's Stoutland notices something and barks)
Steven	Stoutland?
(Stoutland runs off, picks something up off the floor, and brings it to Shauna)
Steven	Looks like he found something.
(Stoutland barks)
Shauna	Oh? Is that for me?
(Shauna takes the object, and Stoutland barks happily; the background music stops, and a mysterious tone plays)
Steven	A shard of ice? How...
(The background music resumes)
Shauna	It may have confused it with a pretty rock!
Steven	There are times when Stoutland does bring me rocks, but... Mistaking ice for a rock?
(Transition back to the room where everyone is gathered)
Looker	So there was a shard of ice at the scene of the crime... Hah—I've got it! Melony! You're the culprit, aren't you?!
Melony	What?! You're accusing me just because there was ice at the scene?
Looker	Here's my reasoning! You worked together with Lapras and made a key to the door out of ice! Then you used the ice key to get into the room and steal the treasure—and made it look locked by locking the door again! The motive could be that you wanted the treasure for a sculpture...
Melony	Hold on a minute! That's all just speculation!
Looker	But the only ones who can freely manipulate ice are you and Lapras!
Melony	That's true, but...
Steven	Wait! Melony isn't the culprit!
Looker	Wh-whaaat?!
(Steven turns around and walks a few paces away from the group)
Steven	Light has been shone on the darkness of this case... The real culprit is...
(Steven turns around and points at someone)
Steven	You!

• Who's the Real Culprit?

Name	Text
Steven	The real culprit is...you! Shauna!
Lyra	Whaaat?!
Shauna	You suspect me, Steven?
Steven	Yes, I'm sure of it. If you want to prove your innocence... I want you to show us that none of Klefki's keys can open the treasure vault. If you can't do that...
Agatha	What do you mean?
Steven	Klefki has this mansion's master key. If my deduction is correct, this mansion should have a master key.
Looker	Whaaat?! How did you guess that? Tell me, Steven!
Steven	Of course. To start, the aim of this game isn't just to guess the culprit. We also have to figure out what happened in this mansion, right? Lyra. You said there's an old painting of a little girl in this mansion, correct? Burgh said it must be a painting of Agatha, the owner of the mansion, but...
(Flashback to Steven talking to Looker and Agatha in the forest)
Steven	This mansion was seized from a prestigious family, and Agatha has only recently started living here.
(Back to present)
Steven	So it would be weird to have an "old" painting of Agatha.
Lyra	Then the girl in the painting is...
Steven	Yes. She's the girl from the prestigious family who used to live in this mansion. What if that girl was looking for a chance to steal the treasure back?
Looker	And you're saying that's Shauna?
Steven	Yes. It wouldn't be strange for the culprit—and by culprit, I mean the original owner of the mansion... to, like Agatha, have special items to help them play their role in this game. I suspect Agatha doesn't have the master key to this mansion...
(Flashback to Steven looking at Shauna's Klefki)
Steven	because when she showed me what keys she had, Klefki didn't express any interest in them.
(Back to present)
Steven	The fact that Klefki have a tendency to like master keys is just further proof.
Shauna	But you could just hide the keys...and Melony could be the girl from the painting, right?
Melony	Aww, a "girl"?
Shauna	And the painting could have been brought in by Agatha! And there was a shard of ice at the crime scene...
Steven	Yes, and that was the conclusive proof.
Shauna	What?
(Flashback to Stoutland giving Shauna the shard of ice)
Steven	My Stoutland gave the shard of ice to you.
(Back to present)
Steven	It knew from the smell left on the ice that you dropped it, Shauna. That's the proof that you left the ice there, so Melony would look suspicious.
(Flashback to Shauna and Steven talking to Melony)
Melony	The ice shard...from when you were talking to me?
(Back to present)
Steven	That's another suspicious thing. Even if you did search the mansion, you're still far too knowledgeable about it.
(Flashbacks to Shauna showing Steven the art studio, the storage room, the balcony, and the treasure vault)
Steven	So knowledgeable that your role could only be someone who's lived here previously! Now, Shauna. Hand over Klefki's keys.
One of Klefki's keys opened the door to the treasure vault...
Shauna	Aw, man. You got me! ♪
(Lear enters the room and approaches the group)
Lear	Amazing, Steven. Everything is as you explained. Shauna was the culprit, and she was given a map of the mansion and the master key along with her outfit.
Shauna	Aww, I couldn't fool Steven!
Steven	No, you were a very good culprit, Shauna.
Looker	You completely fooled me!
Melony	You got me with that cute face of yours!
Shauna	Heehee... ♪
(Melony and Looker chat; Steven and Shauna pose with Burgh watching; Agatha and Lyra talk to Lear)
???	He—he's not here?!
(Guzma looks distraught)
Shauna	Wh-what happened?!
Guzma	My partner Pokémon... was stolen!
(Fade to black)
Yes... A real case that wasn't part of the game has begun!
