SIGN    Kuwata
    General
SIGN    This anime is a work of fiction and has no relation to any actual person or organization. The medical
    procedures and equipment used in the show may vary from what is used to treat individual symptoms.
[00:04] Takao
    In a moment, the person who holds
    the key to this case will appear.
[00:10] Naruse
    The key to this case?
[00:11] Takao
    I set a trap for them.
[00:14] Takao
    And if my deductions prove correct,
    they'll have no choice but to show up tonight.
SIGN    Chairman's Office
[00:20] Naruse
    Who in the world is it?
    And anyway, is there really someone—
[00:30] Takao
    Here they come.
[00:52] Takao
    Don't move!
[00:59] Sakurai
    You're...
[01:04] Naruse
    Director Kuwata Kojiro.
[01:07] Kojiro
    Bah. What in the world?!
    Why are all of you here?!
[01:11] Takao
    Right back at you. What business
    do you have in the chairman's office?
[01:15] Kojiro
    I-I'm just—
[01:16] Takao
    You received a message from
    Kuwata Ryuichiro, didn't you?
[01:20] Takao
    "The issue around the death certificate
     has been dismissed,
[01:23] Takao
    and Seiji is clear of all suspicion."
[01:26] Takao
    "With that settled, I'll announce Seiji's
    appointment as the next chairman tomorrow."
[01:33] Takao
    And then, he probably added, "The police
    want to search the chairman's office,
[01:38] Takao
    so be sure to assist them tomorrow."
[01:40] Kojiro
    H-How do you know all that?
[01:42] Takao
    Those were lies I had
    Kuwata Ryuichiro send to you.
[01:47] Takao
    It was all a trap to lure you out.
[01:51] Kojiro
    What did you say?
[01:53] Sakurai
    Dr. Ameku, why don't you
    let us all in on the secret?
[01:58] Takao
    Sure.
[01:59] Takao
    First of all, how did the
    locked room come into existence?
[02:03] Takao
    If Kuwata Seiji wasn't to blame,
[02:06] Takao
    there was a good chance Kuwata Daiki snuck
    into the study and locked the door from inside.
[02:12] Takao
    If so, why did he do that?
[02:15] Sakurai
    Perhaps he was trying to steal
    valuables from the study?
[02:19] Takao
    But nothing in the room was disturbed.
[02:23] Takao
    So I started wondering...
[02:25] Takao
    What if he snuck into the room 
    to put something there?
[02:31] Sakurai
    The police conducted a thorough search,
    but nothing unusual was found in the study.
[02:38] Takao
    I figured as much.
[02:39] Takao
    But there was a clue in the footage of the
    incident that any doctor should've noticed.
[02:44] Takao
    Kotori, you noticed it, didn't you?
[02:47] Yu
    Yes. The director's actions after discovering
     Kuwata Daiki were clearly strange.
[02:54] Yu
    I just don't know why he did what he did.
[02:58] Naruse
    I watched that video myself.
[03:01] Naruse
    He confirmed the victim's heart
    had stopped and started compressions.
[03:06] Naruse
    I didn't notice anything strange.
[03:10] Yu
    His actions were fine for a normal person.
[03:13] Yu
    However, the director is a cardiologist.
[03:16] Sakurai
    What does that change?
[03:18] Yu
    Any doctor experienced in first aid
    would call out to the patient,
[03:23] Yu
    then tap them to see if they're conscious.
[03:27] Yu
    But...
[03:29] Takao
    The way you checked his breathing
     and pulse was strange, too.
[03:34] Takao
    Normally, you check the
    carotid artery for a pulse.
[03:37] Takao
    And for breath, you observe the chest rising
    or bring your ear close to the mouth.
[03:43] Takao
    Yet the first thing you did
    was place your ear to his chest.
[03:48] Kojiro
    Well, at the time, I just panicked—
[03:52] Takao
    You were searching, weren't you?
[03:55] Takao
    For the item Kuwata Daiki
    was trying to put in the study.
[04:01] Takao
    Kuwata Daiki was just
    following instructions.
[04:06] Naruse/Yu
    Huh?
[04:07] Takao
    The two million yen in his bank account
    was probably from this guy, too.
[04:13] Takao
    In other words, he ordered
    Kuwata Daiki to crash the party
[04:16] Takao
    and injure his little brother, Kuwata Seiji.
[04:21] Sakurai
    Why would he do that?
[04:23] Takao
    He wanted to stop the announcement that
    Kuwata Seiji would be the next chairman.
[04:28] Takao
    He thought he was going to be 
    appointed as the next chairman.
[04:33] Takao
    But Kuwata Ryuichiro decided to name
    his son, Seiji, as the next in line.
[04:38] Takao
    That's why he reached out to his nephew,
    Daiki, who he was already in contact with,
[04:43] Takao
    and used him to try to bring Ryuichiro down.
[04:46] Takao
    And he'd do that by using 
    a certain something.
[04:49] Naruse
    A certain something?
[04:50] Takao
    It's something that
    connects him to Kuwata Daiki.
[04:54] Takao
    And he currently has it in his hand.
[05:02] Takao
    Stop him! He's gonna swallow it!
[05:07] Kojiro
    Ow, ow, ow!
[05:09] Kojiro
    L-Let go!
[05:11] Kojiro
    Let go of me!
[05:12] Yu
    A bag?
[05:15] Sakurai
    These are...
[05:16] Takao
    Stimulants.
[05:17] Yu
    Huh?
[05:18] Takao
    Kuwata Daiki was a stimulants dealer.
[05:22] Takao
    This guy had been buying
    stimulants off him and taking them.
[05:27] Sakurai
    How did you come to that conclusion?
[05:29] Takao
    When we talked to him last time,
SIGN    Vaccine Information for Children
[05:31] Takao
    he complained about not having slept
    in days, but he didn't look tired at all.
[05:36] Takao
    That's a side effect of stimulants.
[05:40] Takao
    His morbidly thin body is also a common
    side-effect of a stimulant addiction.
[05:45] Takao
    He was planning to have Daiki
    stash stimulants in the study,
[05:49] Takao
    then report it to the police.
[05:52] Takao
    Kuwata Ryuichiro was probably
    feeling sick at the party
[05:56] Takao
    because this guy had
    drugged him with stimulants.
[06:01] Takao
    He won't be able to make any excuses
[06:03] Takao
    if stimulants are found in his study
    and his urine also tests positive for it.
[06:09] Naruse
    So the reason he came here today...
[06:11] Takao
    Things didn't quite go according to plan,
[06:14] Takao
    but he was still able to get rid of both
    Kuwata Ryuichiro and Kuwata Seiji.
[06:20] Takao
    I'll bet he's the anonymous whistleblower, too.
[06:23] Takao
    Due to all that, he was sure
    he'd be the next chairman.
[06:29] Takao
    But he panicked after receiving
    false information from Ryuichiro,
[06:34] Takao
    and easily fell into my trap.
[06:36] Takao
    He showed up to plant
     stimulants in this room.
[06:41] Sakurai
    I see. For now, we can arrest you
    for possession of stimulants.
[06:46] Naruse
    You'd better tell us how
     you murdered Kuwata Daiki.
[06:50] Kojiro
    W-Wait! That had nothing to do with me!
     I don't know anything!
[06:55] Sakurai
    Sure, sure. You can tell us all
    the details down at the station.
[06:59] Kojiro
    I really don't know anything!
[07:00] Kojiro
    I was just as surprised
    when we entered the study.
[07:10] Takao
    What?!
[07:12] Takao
    You're still going to arrest Kuwata Seiji?!
[07:15] Yu
    Why?
[07:16] Sakurai
    We interrogated Kuwata Kojiro fully
    after what happened last night, but...
[07:21] (Flashback) Kojiro
    It's true that I regularly
    bought stimulants from Daiki.
[07:26] (Flashback) Kojiro
    I was so busy with work,
    I couldn't carry on without them.
[07:31] (Flashback) Kojiro
    But I was really confused
    when I entered the study.
[07:34] (Flashback) Kojiro
    Daiki should've planted the stimulants and
     slipped out, but he'd collapsed on the floor.
[07:39] (Flashback) Kojiro
    My plan would've been discovered
    if the stimulants had been found on him.
[07:44] Kojiro
    That's why I panicked and pretended to
    check for a pulse while searching his body.
[07:49] Kojiro
    I quickly took them from his jacket...
[07:51] (Flashback) Kojiro
    ...but I wasn't the one who killed him!
[07:56] Kojiro
    He admitted to everything you said,
    apart from Kuwata Daiji's murder.
[08:03] Takao
    I thought we'd be able to glean
    new information after his arrest.
[08:09] Sakurai
    Well, now we know what led
    to the incident on that day,
[08:13] Sakurai
    but the most important mystery
    still hasn't been solved.
[08:19] Sakurai
    Do you know, Dr. Ameku, how
    a person can drown in a locked room?
[08:25] Sakurai
    Kuwata Seiji will remain our most
    likely suspect until that mystery is solved.
[08:33] Sakurai
    The way it's going, he'll be arrested
     within the next few days.
[08:40] Yu
    No way.

[08:47] Takao
    A locked room that
    didn't even have a faucet...
[08:50] Takao
    Was the water brought in?
[08:52] Takao
    Or was the room somehow
    locked from outside?
[08:54] Takao
    But there were no traces...
[08:57] Takao
    The men who first entered
    the room... No, that's not it.
[09:01] Takao
    To begin with, why did the culprit
    need it to be a locked room?
[09:06] Yu
    Hello, Takanashi speaking.
[09:12] Yu
    I understand. I'll let Dr. Takao know.
[09:18] Yu
    That was Sakurai-san.
[09:19] Takao
    What'd he say?
[09:21] Yu
    A warrant's being prepared
    for the arrest of Kuwata Seiji.
[09:26] Yu
    Kuwata-senpai will be arrested tomorrow.
[09:29] Takao
    No... That means you'll have to...
[09:33] Yu
    Unfortunately.
[09:36] Takao
    T-Tomorrow, right?
[09:38] Takao
    Kuwata Seiji won't be arrested until then?
[09:40] Takao
    Then, I just need to prove
    he's not to blame tonight!
[09:44] Takao
    How can you drown a man in a locked room?
[09:47] Takao
    There's... There's gotta be a way!
[09:51] Takao
    I just haven't thought of it yet!
[09:56] Yu
    Dr. Takao.

[10:06] Takao
    Not yet. We can still make it.
    We can still keep—
[10:10] Yu
    That's enough, Dr. Takao.
[10:12] Yu
    I'm satisfied with the fact
    you've already gone this far.
[10:15] Takao
    What are you saying?
[10:17] Takao
    If I don't solve this mystery, you'll...
[10:20] Yu
    Yes, I won't be able to stay here.
[10:24] Takao
    Kotori, don't you want to stay?
[10:29] Yu
    I do.
[10:31] Yu
    There are a lot of things
    I still need to learn.
[10:34] Yu
    I'm also worried what kind of trouble
    you'll get into if I'm not here to babysit you.
[10:42] Takao
    I keep telling you not
    to treat me like a child.
[10:45] Yu
    It was a joke.
[10:54] Yu
    These past eight months,
    I've grown a lot as a diagnostician.
[11:00] Yu
    I owe it all to your guidance, Dr. Takao.
[11:03] Yu
    I believe you've also grown as much as me.
[11:09] Takao
    That's not true.
[11:11] Takao
    I've only been able to get
    this far with your support.
[11:15] Takao
    I'm unable to use my talents alone.
[11:21] Yu
    No.
[11:22] Yu
    You may not have noticed,
    but you've changed.
[11:29] Yu
    Have confidence in yourself.

    After all, you're a top-notch diagnostician.

    These last eight months

[11:50] Yu
    Yup, they sure have.
[11:53] Takao
    I think we make a really good pair.
[11:57] Yu
    I agree.
[12:08] Yu
    Dr. Takao, thanks for
    watching out for me up until now.
[12:13] Takao
    Right.
[12:21] Yu
    So, um, I guess Kuwata-senpai
    is the most likely culprit, after all, huh?
[12:27] Yu
    He was so angry about the party.
SIGN    Kuwata Daiki
[12:31] Takao
    You mean it wasn't a locked-room
    mystery in the first place?
[12:34] Takao
    But then, a lot of things don't add up.
[12:37] Takao
    I mean, the guy drowned to death.
[12:40] Takao
    It'd make more sense if he'd beaten the victim
     to death after getting punched in the head.
[12:46] Yu
    Who got punched?
[12:48] Takao
    Huh? Kuwata Seiji, obviously.
[12:51] Yu
    No, no. Kuwata-senpai didn't
    get punched by his brother.
[12:56] Takao
    Huh? What are you talking about?
[12:58] Takao
    Didn't he lose a lot of blood
    after being punched in the head?
[13:01] Yu
    No, I don't think so.
[13:04] Yu
    It's difficult to cut deep enough to
    require forehead stitches with just a punch.
[13:10] Yu
    But you see lots of blood dripping down
    people's faces in boxing and stuff.
[13:14] Yu
    That's due to cuts near the eyelid
     or the corner of the eye.
[13:18] Yu
    For a forehead cut that bad, you'd need
    to strike it with harder parts of the body.
[13:23] Yu
    Like a strike from an elbow or a knee...

    It's locked!
[13:28] (Flashback) Ryuichiro
    He coughed up a fountain.
[13:28] (Flashback) Emergency Doctor

    backflowing up the tube.
[13:30] (Flashback) Seiji
    Grabbed my jacket 
    with both hands.
[13:32] (Flashback) Yu
    Kuwata-senpai didn't get 
    punched by his brother.
[13:34] (Flashback) Yu
    You'd need to strike it
     with harder parts of the body.
[13:46] Takao
    A star.
[13:47] Yu
    A star?
[13:49] Takao
    A star. It was a star.
[13:52] Takao
    Kotori, I saw a star!
[13:57] Yu
    A star? What does that mean?
[14:00] Takao
    I owe it all to you.
[14:01] Yu
    Huh?
[14:03] Takao
    Gather up everyone involved right away.
[14:05] Yu
    Dr. Takao, does this mean...
[14:09] Takao
    Yeah.
[14:12] Takao
    I'll give you my diagnosis for this mystery.
SIGN    Ameku M.D.: Doctor Detective
[14:21] Sakurai
    Dr. Ameku, is it true you've solved the case?
[14:26] Takao
    Yeah, it's true.
[14:28] Takao
    I'll explain everything now.
[14:31] Takao
    That's why I gathered you all here.
[14:35] Naruse
    Are you trying to say
    the real culprit is in this room?
[14:39] Takao
    The biggest mystery in this case was how
    Kuwata Daiki could have drowned to death.
[14:47] Takao
    And the reason I couldn't solve this mystery
    was because I made one incorrect assumption.
[14:54] Takao
    I believed Kuwata Daiki had punched
    his younger brother at the party.
[14:59] Takao
    But Kotori pointed out my mistake.
[15:03] Takao
    Your brother didn't punch you, did he?
[15:07] Seiji
    That's right.
[15:09] Seiji
    He grabbed my jacket with
    both hands and headbutted me.
[15:15] Naruse
    Does it matter whether he was punched
    or headbutted? He got hurt all the same.
[15:20] Takao
    It's not the same. Not at all.
[15:23] Takao
    I realized something after finding out
    Kuwata Daiki had likely headbutted his brother.
[15:30] Takao
    I'd missed a star.
[15:36] Naruse
    Huh?
[15:37] Naruse
    How is any of this related to stars?
[15:39] Takao
    Let me explain.
[15:47] Seiji
    A CT scan of the head?
[15:48] Takao
    Yeah. Kuwata Daiki's, in this case.
[15:51] Takao
    The cerebral swelling
    in this image was so severe,
[15:54] Takao
    I didn't notice another finding.
[15:57] Takao
    Here.
[15:59] Takao
    It's faint, but you can just
    make out a star. The Star of David.
[16:04] Seiji/Yuko
    Huh?
[16:06] Yu
    SAH?
[16:07] Sakurai
    What's SAH?
[16:10] Yu
    A subarachnoid hemorrhage.
[16:12] Yu
    When a patient has a subarachnoid hemorrhage,
    a white pentagon appears in the center.
[16:18] Yu
    It's called the Star of David.
[16:21] Takao
    It shows very faintly on the image,
[16:24] Takao
    but Kuwata Daiki definitely had
    a subarachnoid hemorrhage that day.
[16:30] Seiji
    Does that mean...
[16:31] Takao
    That's right. He got it
    when he headbutted you.
[16:36] Takao
    The impact caused a traumatic
    subarachnoid hemorrhage.
[16:40] Sakurai
    Hold on a second.
[16:42] Sakurai
    Folk with subarachnoid hemorrhages
    lose consciousness on the spot,
[16:47] Sakurai
    and lose all ability to move, don't they?
[16:49] Takao
    Only in severe cases.
[16:51] Takao
    If the amount of bleeding is small,
    it may only manifest as a mild headache.
[16:55] Sakurai
    Um, but didn't the victim die from drowning?
[17:01] Takao
    He sure did.
[17:02] Takao
    On the day of the incident,
[17:04] Takao
    Kuwata Daiki left the party hall after
    suffering a subarachnoid hemorrhage.
[17:09] Takao
    A few hours later, he came back to
    the mansion, blending in with the guests.
[17:14] Takao
    He snuck into the study on the third floor
    and locked the door from the inside.
[17:19] Takao
    Then, he started planting the stimulants
    in the room, as Kuwata Kojiro had instructed.
[17:24] Takao
    That's when it happened.
[17:42] Takao
    The water that drowned Kuwata Daiki
[17:45] Takao
    was produced by his own body.
[17:50] Sakurai
    His own body?
[17:51] Takao
    That's right.
[17:52] Takao
    To be precise, a pulmonary edema
    caused water to leak into his lungs.
[17:58] Naruse
    What's a pulmonary edema?
[17:59] Yu
    It's a condition where water accumulates
    in the lungs, making it impossible to breathe.
[18:04] Takao
    Kuwata Daiki suffered
    a severe acute pulmonary edema,
SIGN    Internal Line: 05 Reception Room
SIGN    Call Ended
[18:07] Takao
    so he tried to call for help on
    the internal line and leave the room.
[18:12] Takao
    But he ran out of strength.
[18:17] Seiji
    But Dr. Ameku...
[18:19] Takao
    Hm? What is it?
[18:21] Seiji
    What caused the pulmonary
     edema in my brother?
[18:25] Takao
    Huh?
[18:26] Takao
    Kotori. You know, right?
[18:29] Takao
    I haven't mentored you
    for eight months for nothing.
[18:33] Yu
    It was a neurogenic pulmonary edema
    caused by the subarachnoid hemorrhage.
[18:39] Takao
    Correct.
[18:41] Yu
    It's a fairly rare type of pulmonary edema,
[18:44] Yu
    where fluid suddenly leaks into the lungs
    hours after trauma to the head,
[18:48] Yu
    making it difficult to breathe.
[18:51] Takao
    Normally, a forensic autopsy would have
    easily revealed this cause of death.
[18:55] Takao
    However, since this guy thought
    his son might be a murderer,
[19:00] Takao
    he cremated the body
    without notifying the police,
[19:03] Takao
    and caused this whole mess.
[19:06] Ryuichiro
    I'm so sorry.
[19:08] Seiji
    Then...
[19:10] Takao
    Yeah, you're not to blame.
[19:17] Takao
    No one murdered Kuwata Daiki
    in the first place.
[19:22] Takao
    Everyone was merely chasing
    after the illusion of a murder case.
[19:28] Takao
    That's the truth of this mystery.
[19:33] Sakurai
    My, my. Thank you again, Dr. Ameku.
[19:38] Sakurai
    I'll take full responsibility
    for reporting this to HQ.
[19:43] Sakurai
    There is no longer a need
    to arrest Dr. Seiji.
[19:46] Takao
    Yeah, I'll leave it with you.
[19:48] Takao
    Okay, Kotori. Let's head back.
[19:52] Yu
    Sure thing.

[20:44] Takao
    I don't care who my subordinates are,
    since I do just fine on my own.
[20:50] Takao
    But it's convenient to have someone
    like you to help with the small stuff—
[20:53] Mai
    Dr. Takao really blows hot and cold.
[20:56] Takao
    I do not! I'm saying that as the director
     of Investigative Pathology—
[20:59] Takao
    Why are you grinning like that, Kotori?
[21:02] Yu
    Oh, no reason.
[21:04] Mazuru
    Please continue to take care
    of my little sister.
[21:07] Yu
    Right.
[21:08] Mai
