Ace detective Miroku-san's case files.
Suz: You know, I've been feeling some weird presence lately.
Aya: A presence?
Suz: Yeah. Kind of like I'm being watched by someone, but when I turn around to check, there's nobody there.
Shi: Must be your imagination.
Suz: No no, there's no way it's just that! Maybe it's a fan of mine, secretly watching from the shadows?
Yum: I cannot think of a single quality that would gain you a fan.
Shi: Kusunoki might have some fans, though. I bet there are some Sentinels who secrely admire you.
Suz: Yeah I can see that.
Meb: What a farce.
Suz: What would you do~? If there was a hidden Mebu fan club?
Meb: Add thirty more hours to their daily training as a part of club's rules.
Suz: That doesn't even make sense time-wise!
Aya: Ah... Now that you mention it, I've noticed something strange lately too.
Yum: Kokudo-san, you too?
Aya: Yeah. I occasionally clean the Sentinels' rooms when they ask me to.
Suz: Oh yeah, I ask her from time to time too. You're so good at making things nice and tidy, Ayaya. You're a lifesaver.
Aya: Thank you very much. But sometimes the things in the room would be scattered in an unnatural way...
Yum: Would that not be the fault of the room's owner?
Aya: Hmm... But I think they were scattered differently from how it normally is. The clothes and things looked like they were violently thrown around...
Shi: Definitely your imagination.
Meb: Yeah. I don't think it's anything serious... But I'll look into it.
Yum: The wind is certainly strong today.
Aya: Apparently there's a typhoon approaching. It will hit Kagawa by night.
Suz: Seriously!? Mebu, I'm scared! What if the Tower falls down? We all need to evacuate right now!
Meb: It won't fall.
Suz: But what if!?
Meb: I'm a carpenter's daughter, you know. The Tower's earthquake and wind resistance are perfect, I've checked.
Suz: Mebu, I'm gonna fall in love right now.
Meb: Alright, I'm off to training.
Suz: Ah. So you're going to train even in a typhoon...
Yum: And thus, night fell. Both wind and rain grew ever stronger. The Sentinels were locked inside the Tower by the storm... And trouble occurred!
Aya: Kyaaaa!
Suz: What's wrong, Ayaya!?
Yum: Is something the matter!?
Aya: I came to return a book I borrowed from Mebuki-senpai... And she...
Suz: Sh-She's dead!
Yum: Mebuki-san... Is sprawled on the floor buck-naked!
Suz: Are you dead!? Mebuuu!
Yum: However, that was merely the beginning of the events.
Sent A: Aah! My room's been ravaged!
Sent B: I saw something glimmer in a corner at the viewing platform! It's a will'o'the'wisp, I tell you!
Sent C: When I came out of the toilet, something attacked me! There's even a wound!
Yum: The string of inexplicable occurences continued.
Suz: Just, just what is happening?
Aya: Mebuki-senpai doesn't seem to be in danger, but she's not well enough to talk yet. The medical staff said there weren't any signs of physical trauma either.
Yum: Due to the typhoon, our Gold Tower has completely turned into a locked room. And in this locked room of ours, more and more people fall victims to something.
SHI: Nah, they're probably on the edge and exaggerating. It's gotta be their imagination.
Suz: Oh, so you switched.
Yum: Now that it has come to this... I shall avenge Mebuki-san! I shall solve this mystery and bring the culprit into the daylight! By the name of Miroku!
Suz: Miroku-san, you just wanted to say that.
Yum: First of all, we shall inquire with the suspects.
Aki: To think you asked me to suddenly come to the viewing platform... To give a testimony?
Suz: Oh yeah, I bet Sensei could kill someone without batting an eye.
Aki: Kagajou-san.
Suz: Just kidding! I don't actually think you would kill a fellow man in cold blood or anything!
Aki: ...A fellow man? Now that's just weird. I'm a woman.
Suz: ...That's your problem?
Yum: So, miss, what have you been doing tonight and where?
Aki: Alibi inquiry, huh. I'm afraid I have no alibi to prove that I was in my room... Hmm. That reminds me, there's a certain legend told here in the Gold Tower.
Suz: Why is she suddenly talking about legends?
Yum: Suzume-san, this flow of events is a given.
Aki: This tower is called Senkeiden in the Taisha. Sen as in "a thousand", kei from "view" and den from "palace". Thus, Senkeiden - Palace of Thousand Views. The Uesato family directly named it so.
Yum: This is my first time hearing of this.
Aki: But the name "Senkeiden"... Is actually rumoured to have something to do with a girl who met an untimely end...
Yum: Could it be... That the girl's grudge...
Aki: It's just a legend... Nothing more than a story.
Suz: I-I'm scared, Miroku-san! Is it a ghost!? A ghost!?
Yum: W-Whether it is a ghost or not is something we must find out starting now!
Aya: T-There's trouble!
Yum: What is it, Kokudo-san?
Aya: Shizuku-senpai suddenly left the Gold Tower and said she's going to the training grounds!
Yum: I see... So that was it. This mystery... is solved!
SHI: Jeez. Shizuku can be a pain in the ass too...
Suz: That's as far as you go, SHIZUKU!
SHI: Huh!? Why are you all here?
Yum: Mebuki-san's murdererer is you, SHIZUKU-san, is it not?
Aya: Miroku-senpai, she's alive.
SHI: I'm the culprit? And why is that?
Yum: Your personality change. After Mebuki-san got attacked, Shizuku and you traded places for some reason.
SHI: And what's that supposed to prove?
Yum: Allow me to explain: Mebuki-san proposed you to have a match, with your attitude on the line. However, you lost to her, and the grudge finally drove you to murder!
Aya: She's not dead.
Yum: And once you learned that I, Miroku Yumiko, was on the case, you quickly fled here, afraid that your crime would be discovered.
SHI: Hold on-!
Yum: Now that I remember, you kept suggesting all those events were just people's imagination. All that was to mislead the investigation-
Meb: That's not it, Miroku-san.
Yum: Eh? Mebuki-san, why are you here?
Aya: Mebuki-senpai! You woke up!
Meb: Yeah. And the culprit behind these events... is this.
Cat: Meow.
Suz: Uh... What's this creature?
SHI: Haah... What's this look like to you, a dog? It's a cat, a cat.
Cat: Meow.
Suz: Oh, it just made a cat-like sound.
SHI: That's 'cause it's a goddamn cat! Okay, fine! I'll explain. So, basically...
SHI: ...And that's the gist of it.
Yum: Uh, so to reiterate... The cat you picked up and secretly kept would sometimes escape and cause a mess in the Sentinels' rooms?
Meb: The will'o'the'wisp glowing in the darkness must've been its eyes reflecting light. The girl that got injured must've accidentally startled it and got scratched as a result.
Yum: And the reason you were passed out?
Meb: Ugh... That's because I got exhausted from today's training and spent too much time in the bath...
Aya: We were worried! Please don't overdo it.
Meb: I'll be more careful from now on. Sorry for worrying you.
Yum: ...T-then the reason you swapped personalities?
SHI: Shizuku was trying to catch this mischievous kitten and scold it, but it scratched her. So I got brought out.
Suz: Miroku-san... "The mystery is solved!" was it?
Yum: O-O-O-O-O-Of course I knew all along! I was merely testing you all!
Suz: Ew, that's the lamest kind of excuse.
Cat: Meow.
Meb: So, what are we going to do with it, SHIZUKU?
SHI: Shizuku's been keeping it in secret because she wasn't sure if she'd get a permission to, but now that it's caused such a mess we can't really keep it hidden anymore.
Aya: What if they tell us to throw it out? I feel bad for the kitty...
Meb: Haah... I'll ask for a permission to keep it as well.
Suz: Mebu, you really are kind, after all.
Yum: She is a tsundere, after all. That is one of the points she shares with Miyoshi-san.
Meb: N-No I'm not!
