Gokumon Prep School's retreat.
At Sunlight Mansion and Moonlight Mansion, four students have been murdered.
Moonlight Mansion
It seemed the murders were over when the one student without an alibi committed suicide.
But the Puppeteer from Hell, Takatou Youichi, is laughing from the shadows.
I can't afford to lose to him.
I swear I'll uncover the identity of the real killer, Sparrow!
I swear it in the name of my grandfather!

The Prison Prep School Murder Case!
Sunlight Mansion
The prefectural police are already on their way.
But I'm shocked, Akechi-san.
Ujie Takayuki Head Instructor
I had no idea you were a superintendent with the Metro Police Department.
Can I count on your cooperation with the investigation?
Of course.
Then I'd like to have a look at the layout of Moonlight Mansion here.
I don't actually have blueprints or anything.
Then Nanase-san, would you be my assistant and help me with the investigation?
M-Me?!
I'd like you to draw the layout of Moonlight Mansion.
O-Okay.
Wear gloves in case you come across something.
You'll find gloves in the first-floor locker, where Konoe-kun went to get chalk.
Please wear two pairs.
Understood.
Something terrible has happened, but please stay calm, everyone.
Inspector Akechi from the Metro Police Department is at Moonlight Mansion.
Who knew that hot teacher was a police inspector?!
Yeah...
And Inspector Akechi has instructed us
Itsukushima Ranko Deputy Head Instructor
to cooperate with Kindaichi-kun for the investigation here at Sunlight Mansion.
With Kindaichi?!
He's the grandson of a famous detective
and seems to have a history of aiding police investigations
by getting to the bottom of the case at hand.
But Sensei, Kirisawa was the killer, and he committed suicide,
so isn't the case closed already?
I'm not so sure.
In fact, I don't think even one part of the truth has come to light.
At this rate, the truth will be buried in darkness.
Please cooperate with me, everyone.
Akao Ichiyou Instructor
There are the gloves.
It feels like something's strange though...
I wonder what it is.
Shikibu-san, first, please tell me about Enami Yurika.
She was allergic to buckwheat flour?
Shikibu Seiko Prep School Student (Humanities)
Yes. If she had even just a mouthful of something with buckwheat flour,
she told me that it could be fatal.
She always checked to make sure there wasn't any of it in her food.
I see.
Next, what did you think of Kujiragi?
What did I think?
Like, did you hate him enough to kill him?
O-Of course not! Although I did think he was annoying.
He would always blow his stack like that over little things.
I didn't want to get involved with him and end up like Aino-kun...
Aino?
You mean Aino Shuuji, the former Gokumon student who died from an illness?
I-I don't know!
Hama Akiko Prep School Student (Humanities)
Hama-san, what kind of person was Kujiragi?
I don't know much about Kujiragi-kun.
Then what about the uproar over the textbook?
He had cheated before.
No, that's not what I mean.
I mean when Kujiragi made a big stink about missing textbook.
Oh, sorry!
I was concentrating on studying in my own room, so I didn't notice.
I tried not to get close to Kujiragi-kun.
They would harass people for no reason, just for kicks.
I became their target once, too.
You too? So someone else had been a target, right?
Maybe Aino Shuuji?
I don't really want to talk about that.
Can we be done here?
Nakayashiki Manabu Prep School Student (Humanities)
Yeah. Almost everybody hated Kujiragi.
Especially because he always pitched fits over stuff.
Remember how he kept pounding on doors when he lost his textbook?
I ignored him then.
Yeah.
More importantly, Kindaichi, about these murders...
Don't you think it has something to do with Aino Shuuji's death?
Why do you think so, Nakayashiki?
The day before Aino died, none of the six people who were murdered here were at school.
Moroi Ren Prep School Student (Humanities)
Moroi.
Konoe Motohiko Prep School Student (Science)
Konoe.
Kaidou Hitomi Prep School Student (Science)
Kaidou.
Enami Yurika Prep School Student (Humanities)
Enami.
Kujiragi Daisuke Prep School Student (Humanities)
Kujiragi.
Kirisawa Tooru Prep School Student (Science)
Kirisawa.
None of them?
Yeah. I suspect those six have something to do with Aino's death.
Souta, tell me.
What happened between the six kids who were murdered and Aino Shuuji?
Murakami Souta
Aino was a little too good.
He had far and away the best scores in everything.
And it wasn't just academics.
Sick or not, he had a great personality, too.
Those six used to be number one in one subject each,
but they all lost their top ranking when Aino started going to the school.
Kirisawa's scores did a downward slide, to where it looked like he'd have to quit.
Driven into a corner, Kujiragi started cheating.
And they all started harassing Aino.
But he never complained once.
For a nice guy like that to die...
Hey, Souta, what was the real cause of his death?
You know something, don't you?
They switched it.
The medicine Aino injected himself with every day for his illness...
They switched it with something else!
Aino-kun worked harder than anyone.
He excelled in all of the subjects.
I visited his workplace once.
He keeps those headphones on like that
and studies vocabulary words or mathematical equations or historical eras.
But he also works twice as hard as anybody else. He's really something.
I'll probably never get a wonderful student like that again.
Layout of Moonlight Mansion
You did a really thorough job drawing this.
I'll just be happy if it's useful.
This building used to be a hospital facility,
but you made major renovations, correct?
Yes. I originally had dreams of being an architect, you see.
Where and how did you change it?
Nothing really major.
Mainly, I got rid of the interior decorating so it wouldn't distract the students.
Hey, Kindaichi!
I rounded up some muscle
to throw a cordon around Sunlight Mansion before the prefectural police get there.
We'll nab Takatou, even in disguise as a prep school teacher.
Thanks. I'm counting on you, old man.
The thing is, I don't have any hard evidence that Takatou committed any crimes yet.
At this rate, you won't be able to take him into custody.
There's one person whose testimony rings false,
but they have a cast-iron alibi, too.
Oh, that's right. I've got important info.
Aino Shuuji, who died of an illness? His father is that instructor, Ujie.
What?! Ujie-sensei and Aino are father and son?!
Yeah. Apparently the son he had before his current marriage.
Yes, Kindaichi-kun. I heard, too.
There was something that bothered me about Ujie-sensei.
On the legs?
It was obviously strange.
And did you get my fax?
Yeah. The Moonlight Mansion schedule and layout of the place.
Layout of Moonlight Mansion
I'll compare it with Sunlight Mansion's.
I'm sure Inspector Kenmochi already has the perimeter surrounded.
We've just about reached the time limit, Kindaichi-kun.
Dammit! He must've laid a trap somewhere in here!

This inexplicable layout. And...

Miyuki...
Hajime-chan, good luck figuring it out.
I thought maybe it would come in handy, so I took photos of Moonlight Mansion.
Thank you, Miyuki.
I don't know what it was, but I got a weird feeling
when I looked inside the locker where Konoe-kun got the chalk.
A weird feeling?
Moonlight Mansion
It's beautiful when lit up at night.
Sunlight Mansion
Don't tell me...
Could it be...
What's wrong, Kindaichi?
Did something happen, Kindaichi?
Numbers!
117... That's the phone number to get the time.
I see... Now it makes sense!
Itsukushima-sensei, please have all the members of Moonlight Mansion
come to Sunlight Mansion right away!
W-What do you mean?
Layout of Moonlight Mansion
Layout of Sunlight Mansion
An iron-clad alibi, a puzzling layout, and throwing water on the legs...
Moonlight Mansion
It's all tied together!
I've solved all of the mysteries!
The Case File of Young Kindaichi Returns
Sunlight Mansion
What's this about, Kindaichi-kun?
Calling us all the way over here...
I've gotten to the bottom of these serial murders.
The person who killed five students here at Gokumon's retreat...
That murderer, Sparrow, is among us!
W-What are you talking about, Kindaichi?
The killer is one of us?
That's ridiculous!
The murders in both mansions took place during class time!
Everyone here was in a classroom.
None of us could've committed a murder!
It was indeed possible.
The killer, Sparrow, listened to a certain demonic man
and made the impossible possible!
Oh? Tell us how it was done, Kindaichi-kun.
Share your so-called deductions.
These serial slayings began with the murder of Moroi Ren
back at the actual Gokumon school.
Sparrow murdered the six students, including Moroi, because they were unforgivable.
Specifically, they drove a student to his death.
Moroi had already quit the school, so the killer targeted him when he came for that test.
Sparrow murdered the rest one by one at this retreat.
At first glance, it looks like everyone here has an airtight alibi.
But when I compared the schedules of Moonlight Mansion and Sunlight Mansion,
I noticed something odd.
When a murder happened at Sunlight Mansion,
Bathroom break
Move from 2nd floor to 3rd floor Class in room 3E
everyone at Moonlight Mansion was on break or eating, so no one there has an alibi.
On the other hand, when a murder happened at Moonlight Mansion,
Move from 2nd floor to 1st floor Class in room 1A
Self-study in students' rooms (teacher making the rounds) Move from 2nd floor to 3rd floor
it was a free hour at Sunlight Mansion, so no one there has an alibi.
It's as if the schedules were made to allow for the murders to happen.
I don't see what you're getting at.
There were actually two killers.
One at Moonlight Mansion, one at Sunlight Mansion.
The Sunlight Mansion murderer waited for the perfect time to kill Konoe and Kaidou,
Moonlight Mansion
when the Moonlight Mansion murderer had an alibi.
How?! Konoe-kun and Kaidou-san left the classroom by chance!
It wasn't by chance.
That's right. It was a cleverly constructed necessity.
In Moonlight Mansion,
there's only one person who could've passed off this necessity as a coincidence.
That's you, Ujie Takayuki-sensei.
Ujie-sensei?!
Yes. There are two Sparrows.
The first one, at Moonlight Mansion...
...is you, Ujie-sensei!
You're the one who sent Konoe-kun to the hallway to get chalk, correct?
T-This isn't even funny!
Are you saying I had Konoe-kun leave the classroom to be killed?!
T-Then what about Kaidou Hitomi?
She left the classroom because she just happened to finish the biology test quickly.
She didn't "just happen to".
This is Nanase-san's test from that class.
Two of these questions are extremely hard and impossible to solve during the class time.
But Kaidou-san finished it in no time and left the room, didn't she?
S-So what?!
In other words, only Kaidou-san's test
had hints in it that helped her answer the questions fast.
You're the only one who could've done that.
And since you collected all the tests, there would be no proof left.
Similarly, a clever contrivance was used to make Enami Yurika at Sunlight Mansion
go into the hallway.
Having no idea she was about to be murdered by Ujie-sensei.
Enami-kun left the classroom because of a stomachache!
It was a total accident!
Enami's Calorie Get from that afternoon was poisoned!
How can that be? We all randomly took the Calorie Gets then.
How can hers have been poisoned when no one knew which one she'd take?!
The poison was mixed into all of the Calorie Gets!
It can't be! I didn't feel a thing!
Neither did I!
That's because we drank a poison neutralizing agent.
Neutralizing agent?
Each bottle of the buckwheat flour tea we were given
had an antidote in it that neutralized the poison.
Only Enami Yurika poured her buckwheat flour tea down the sink.
That's because she...
was allergic!
That's right. Because of her terrible allergy, only Enami didn't drink the antidote,
so she got an upset stomach and went to the bathroom during class, as the killer planned.
W-What about Kujiragi?
He was kicked out of class for cheating!
That was a psychological inducing trick.
The other killer in Sunlight Mansion
tore the page out of Kujiragi's textbook
and nonchalantly dropped it on the floor during the test.
Huh? Someone dropped their eraser...
What is this?! A cheat sheet!
Kujiragi had cheated before, so he was kicked out of class immediately.
And then...
H-Have you forgotten?!
In the first place, it takes an hour to get from Moonlight Mansion to Sunlight Mansion!
There are only a scant ten minutes between classes!
It's impossible to commit murder at Sunlight and then return to Moonlight in ten minutes!
Certainly, using that road by bike or car would've been impossible.
Then by the river? Using a boat...
Out of the question. Getting here may be easy,
but the current is fast, so even with an engine, coming back would take too long.
It's completely impossible!
The killer made the impossible possible.
The killer used a trick to make the distance between both mansions zero!
Zero?!
W-What are you talking about?!
Hey, Miyuki. Compared to Moonlight Mansion,
what's different about this Sunlight Mansion?
What's different? Um...
They're both drab, and the entryway and cafeteria are about the same...
It doesn't feel like there's much of a difference at all.
Yeah, right?
What about it?
That's right. Nobody noticed.
The five murders that took place yesterday,
Miyuki's science group, my humanities group...
It was actually all here, in Sunlight Mansion!
I-It can't be...
Ujie-sensei, you cleverly guided us, didn't you?
On the first night, you had the Moonlight Mansion students gather
while you quickly went to their rooms, put their things in your backpack,
and went out for the night walk.
We took a circuitous path anyway,
so with only a flashlight to guide us, no one knew where we were going.
You led us right to Sunlight Mansion.
Sunlight Mansion
Moonlight Mansion
And while everyone was taking my class, you ran to the 2nd floor
and put the students' things in the rooms.
Having the students put their shoes in lockers
and keeping their belongings to a bare minimum
was so you could bring the science group students to Sunlight Mansion.
B-But Kindaichi, if everyone was in Sunlight Mansion, we would've run into each other!
Nope. Look at the layouts for both places.
Layout of Sunlight Mansion
Layout of Moonlight Mansion
All of the stairways were locked.
Even if humanities and science were on the 2nd floor at the same time,
the locked recreation room was used as a wall
to keep the east wing and west wing members from crossing paths.
Y-You're right!
Our science group only used the 2nd floor's west wing.
Our humanities group only used the east wing!
The stairways for the east and west wings are separate, too.
On top of that, the schedules for the two groups were skillfully staggered.
When the humanities group had a class on the 3rd floor,
the science group was having dinner in the 1st floor cafeteria.
When the humanities group was in the cafeteria, the science group was on a night walk.
And so, while no one noticed they were in Sunlight Mansion,
Ujie-sensei took the science group back to Moonlight Mansion.
Sunlight Mansion
Moonlight Mansion
Does that make sense?
If Konoe-kun and Kaidou-san were murdered in Sunlight Mansion,
why were their bodies found in Moonlight Mansion?
The Sunlight Mansion killer put Konoe and Kaidou into strong plastic bags
and then tossed them in the river in an inner tube or something.
They floated downstream to Moonlight Mansion, where they were stopped by a strung rope.
Ujie-sensei set the bodies up
and if Akechi-san discovered them, everything would be perfect.
But then an accident happened here.
An accident?
Maybe the plastic bag wasn't sealed well or there was a hole,
but Konoe-kun's legs got wet.
To disguise that,
you set the body on fire and purposely threw water on him in front of me.
That's why you threw water on his legs, which weren't on fire, instead of his upper body.
And to smooth over the unnaturalness of setting a corpse on fire,
Combustion
you talked about combustion in chemistry class so it would look like a "theme murder".
Kaidou's double helix, Enami's Bamboo-Cutter, and Kujiragi's Demons
The Tale of the Bamboo-Cutter
were all camouflage to cover up the fact that Konoe's corpse was wet!
That's the true reason for the theme murders!
It was all the Puppeteer from Hell's idea.
Ujie-sensei and the other killer
carried out the murderous scenario he concocted.
That's right. There's one more killer.
From Sunlight Mansion.
The person manipulated by the Puppeteer from Hell into committing serial murders.
The other "Sparrow"...
...is in this room!

The serial killings that were staged with bold, clever tricks
are connected to the death of former prep school student Aino Shuuji.

but I've cornered you at last! I'm going to reveal your whole scheme!
