So Makoto and siramay went to the elevator.

Siramay: oh I almost forgot! During this finally trial YOU CAN'T
and I repeat CAN'T
look at me or speak if you wanna say something to me just think it I can read your thoughts and speak back, I don't want zetsu knowing you can see me it's important for the universe got it?

Makoto: ok I understand… also why do you have a guitar?

Siramay: dramatic effect
But also!
flips it revealing a keyboard
Cause music.

So they were in the elevator tense except monokuma who was hammy.

Monokuma: This final class trial is gonna be slathered in pitch-black despair! Climaximum sorrow!

Siramay: climaximum?

Monokuma: nods
climaximum

Siramay: ok then buddy!
thumbs up.

And after more ham he disappeared

I started making my way toward the opening. Step after step toward that gaping maw... I'd resolved that this would be the last time. I repeated to myself that there was no fear, no mystery left. I pushed my anxiety down, calmed my trembling body. And finally, on steady legs...I passed the threshold and stood in the elevator. Without warning it began to descend... Deeper and deeper...Deeper...deeper...deeper still. Deeper and deeper, deeper, and deeper, deeper, and deeper...Deeper and deeper it fell... I closed my eyes, and sight fell away. All sound, too, disappeared. Alone in the universe, I waited for the elevator doors to open for the last time. What could have been seconds or centuries later...I felt the gentle vibration of the elevator come to an end. I slowly opened my eyes.

Makoto: This...is the final trial site?

Monokuma: Whaddya think? Isn't it just the perfect background for deciding a person's fate!? It's the long-awaited last stage! The always-exciting final boss battle! Puhuhu... And I'm gonna sit in on this one! I'll just sit right here in the vacant sixteenth seat!

Siramay: and that's why I didn't stand there.

Monokuma: Well then! Let's...BEGIIIIIIIIIIIINNN!

Siramay: we're all gonna die!
:D

And so the trial started which started with everyone saying how everyone was the mastermind besides them, really silly the only time I could see that scenario working out is if everything that happened was all an elaborate prank for kicks and giggles, but I feel that it be to elaborate in that case thankfully Makoto was able to talk them out of it.

Makoto: The mastermind laid a trap to make us each think everyone else was working against us!

Monokuma: Huh? I laid a trap. A trap!? How rude! What grounds do you have for such audacious accusations!?

Siramay: on the grounds that you're a huge jerk!

Monokuma: how dare you.

Siramay: its true though, but what I think you mean is how BEAR you

Monokuma: …
only I'm allowed to make bear puns.

Siramay: :(

But yeah Makoto pointed out how they aren't in the photos because they took the photos also byakuya showed his

FIIISSSSHHHHHH

I don't think mukuro has straps on in this picture oooo dirty girl but no bad me no thoughts! Gosh darn I've seen the picture so much I'm looking for new things oi woi woi.

Needless to say now everyone thought they were fake but monokuma assure they were real in which Makoto realized they all had amnesia though everyone was suspect of this thankfully Makoto had proof to back up his claim with the video interview in which Makoto went on and on about it and even though none of them could accept it monokuma confirmed it the truth because they stole the memories.

Monokuma: If I said it was hypnotism, would you believe me? Or we opened up your skulls and messed with your brains? Would you really believe anything I said? How it happened doesn't matter right now!

Siramay: ou I know!
siramay happily clapped his hands
It a long beautifully tragic story about a stupid simp trying to cure the woman he loves sigh…
siramay sighed romantically before shaking his head and straining up
but yeah that's not important now maybe later when all this blows over.

Needless to say they wondered why Mr. Kuma had to erase their memory but that part was still a secret at the moment, so they were left wondering but now back onto mukuro my precious puppy girl, so they talk about the masterminds location with Makoto brings up the masterminds lair in which byakuya says it's probably one of them then we all blame Makoto.

Toko: I blame M-Makoto!

Makoto: What!? Why me!?

Toko: C-Cuz! It's super weird how you're the o-only one who survived being executed!

Siramay: that's fair

Yasuhiro: Oh, I get it! The only way he coulda survived is if he was actually the mastermind himself, right!?

Monokuma: Aww nuts! Ya got me!

Makoto: W-Wait, what are you trying to say!?

Siramay: AH YES IT WAS HE ALL ALONG AND NOW HE WILL CHANGE CLOSE AND SHOW HIS RED EYE TO REVEAL HES ACTUALY A HOT EDGEY BAD BOY LIKE ALL THE FAN ART ONLINE

Then siramay made beastly slobbering sounds clutching his mouth at the though

Makoto: SIRAMAY

Siramay: what I can't help it I like evil! And evil you is hot
hahah maybe in that other world zetsu is the ultimate goody protagonist I pester around hahahh.

Anyway thankfully Kyoko settled them down by saying how they shouldn't bicker and instead find out the personality of mukuro…I mean the murder of mukuro in which they confirmed that mukuro was murdered by her old wounds witch brings to mind mukuro was murdered long before the events of the 5th case then they had to convince toko witch was fair course it was easy since it was on her report so they proved the wounds killed her then they talked about how Makoto was attacked at night but of course Makoto could easily state it was the mastermind but monokuma jumped in and denied the accusation saying they didn't do it (aka a bold face lie)

No, there's no way Mukuro is the one that attacked me... Even if I didn't see their face... If you compared what we know about Mukuro to the masked attacker...it should be obvious!

Wait! You're saying those are her hands!? I though those where gloves!

Why?

Uh well er I mean you'll understand when you see zetsu!

Monokuma: You never saw their face, right? So you can't have any idea who was under that mask! I'm telling you now, it was Mukuro Ikusaba!

Kyoko: You're wrong. Even without seeing their face...there's another part of the attacker we can use to prove it wasn't her.

Monokuma: Oh? And what is this other part? Is it the right hand? Or the left hand? Maybe the right foot? Or perhaps the left foot? Or could it be... the hips!?

Siramay: BA BAH BAH BAH BADABADA BA BAH BAH BAH BADADADA BA BAH BAH BAH BAH BA BAAAAH
Shakira! Shakira!
I'm on tonight
You know my hips don't lie
And I'm starting to feel it's right
All the attraction, the tension
Don't you see, baby, this is perfection?

Monokuma: really?

Siramay: what? You know she liked Shakira music, I know she liked Shakira music
so you can't just mention the hips and not expect me to sing hips don't lie.

Makoto: so as I was saying!

While Makoto explained siramay proceeded to dance to Shakira's hips don't lie in the background as Makoto called out the lack of hand tattoo though monokuma still denied they did it though most of the others had them tight as a cat alibi course he still tried to pin Kyoko who showed off her KFH

Siramay: finger licking good.

Makoto: why would you say that.

Siramay: because I can.

Course monokuma as always tried to bounce back from such a blow as the circumstances on mukuros death are still unknown but all that they knew she died after the killing game started and her body was stored in the bio lab which was getting monokuma theatrically antsy as they were another step closer to their true identity, also monokuma mentioned how Makoto's family is held hostage how rude.

Siramay: makooottooooo don't listen to hiiiiim he's just distracting you from the true matter at hand if you are so worked up on your family you won't be able to find clues about the mastermind!
besides I promised you id save your family and that's what I'll do!
so please punch zetsu in the face!

Makoto: I'm not gonna punch them
BUT YEAH!

Then a BTB happened in which Makoto called out the lack of light numbers because by all accounts if the truth be told there should be 10 and as we got closer and closer siramay could see the cogs in Makoto's head turn as someone died twice but who….

Siramay: sos shes in disguise! sos shes in disguise! There's a she wolf in disguise!
siramay said pointing a certain someone's portrait.

Makoto: ! coming out coming out coming out!

Everyone: ?

Makoto: I mean I know who it was!

And this is where things get juicy.

Makoto: Junko... Wasn't her fatal injury pretty similar to Mukuro's?

Aoi: What do you mean...?

Makoto: Well, remember what happened to her? She was impaled by a bunch of spears, all over her body.

Siramay: mukuro whhhhhyyyy

Makoto: so it is her?

Siramay: well you basically know what happens no point in me denying it yeah "Junko" was mukuro.

Makoto: wait… is that why you where so upset when I tried to comfort you on her death?

Siramay: SHE NEVER GOT TO DIE AS HERSELF! No one mourned for her, and you had to say the name of her- that girl not only as if their death taken place but like I cared for them no respect was given for mukuro when she needed it most. So I can't help but be sad whhhhyyyy.

But anyway toko thought it was the other way around and that mukuro disguised junkos corpse as her own witch I guess is a fair guess with your lack of knowledge, but Makoto is quickly able to correct it
and now we get to the moment we all wait for where Makoto finally assumes the mastermind identity.

Siramay: JUUUUUUUUNNNNNNNKKKOOOOOOOOOOOO!

Man I felt the earthquake at that yell.

Sorry but I wasn't able to say her name in so long it feels good to finally let out all that hate.

Course everyone was still a bit confused cause they think Junko is dead, so Makoto has to clarify that that Junko was mukuro in disguise and was like that since the beginning bum bum baaaaaaahhh
and you know on and on and all that.

Monokuma: Fear is only possible where hope is possible. I only have despair, so fear is an alien concept to me. (See Makoto they get it hope and fear)

So anyway they were getting nearer and nearer to revealing her identity…sigh gotta emotionally prepare myself, but I digress so monokuma was still fighting them, but Makoto is a smart egg and proves monokuma is defensive about Junko then another BTB happened then Makoto called out how junkos face never shows up in any of the photos which is hecking suspicious and that's when Makoto made the closing argument
almost tiiimmeee.

Makoto: She needed to hide the body's true identity. She had to make sure we didn't find out it was actually the same person we'd met in the beginning. This is the truth behind Mukuro's murder. And the one who carried it all out is the true mastermind, the one controlling Monokuma... The real Junko Enoshima!

Stressed siramay noises

Makoto: you ok.

Siramay: of course I'm not ok they're almost here!
stressed siramay noises

..so…after Makoto said all that…..monokuma was silent….to silent…. Deadly silent
just like how I am stressed…to stressed!... deadly stressed!
it's almost time!

Aaaahhhhhh

Kyoko: Give it up, Junko. The game's over.

Monokuma: ...Over? Puhu... Puhuhu... Did you really think the story would end once we reached the climax of the case? Wrong! There's still plenty more to go!

And that's when in a puff of smoke she revealed herself and- wait why do I hear guitar music?
I know siramay told me not to look but even still in the corner of my eye I saw it
siramay with the guitar he was holding and though it made sense I still couldn't believe what happened.
