And so, the investigation started, though there wasn't really much to say though an important thing to note was those in strawberry house were trapped there.

But after a while we now switch to the viewpoint of Nagito and what he sees
and what he sees is very interesting, in order to help with the investigation, he took it upon himself to go into the Final Dead room and play the life-threatening game. Using his incredible deduction skills and assisted by Monomi, he managed to clear all of the challenging puzzles scattered throughout the room and earn the right to play Russian Roulette to access the Octagon and the Ultimate Weapon inside it.

With a large amount of faith in his ability as the Ultimate Lucky Student, Nagito loaded the revolver with five bullets instead of one, and pulled the trigger against his head, giving him a one in six chance of surviving. He managed to survive, thanks to his talent and was granted access into the Octagon.

By completing the Final Dead Game, Nagito learned about the Fun House's structure and realized that the building itself is the Ultimate Weapon. Due to completing the Russian Roulette with such a high difficulty, he also got a special prize from Monokuma, the sequel to the first Future Foundation file they had obtained earlier after riding the roller coaster. It revealed absolutely everything…
but that's another tale for another time…

But anyway now back to Hajime who was shocked and a gasp when he saw nagito in grape house (3 guesses as to how he got there) but the point of the matter was he told Hajime of his investigation notes for strawberry house and how he did the final dead room and what he learned there, also nagito has acquired the "sass" skill as he talks about parallels between dr1 and dr2, now to the big thing he reveals he knows Hajime's talent… or lack there of has he has none! Just a simple reserve course student, after some more mocking and more hints he left
and Hajime was very depressed
SO DEPRESSED IT WAS FRUSTRATING

Siramay: WHAT ARE YOU DOING?

Hajime: AH what do you mean!?

Siramay: stop being depressed!

Hajime: Why do you care?!

Siramay: if I have the power to do something I should do it! You said it yourself and while you may not believe me, I take that to heart fully! The worst thing someone can be is a do nothing there's nothing I hate more so right now I'm doing something and telling you! That not being an ultimate doesn't change who you are. As a person you can do great, all you gotta do is get off your but and do something!

[SIRAMAY]
What are you waitin' for?
Pick yourself up from the floor
If you don't respect yourself
You won't get it from no one else
No shame in workin' hard
Let them know that's who you are
Though I'm the dragon in the room
I'm still the best one with this tune
This ain't no step and fetch it
It's all part of the climb
There's a train, I'm gonna catch it
It's a matter of time

But you gotta start somewhere
You gotta start somewhere
You gotta get going or you're never gonna get there
And once you get movin'
You'll find some way somehow
And it might as well be right here right now
Come on boy!
You gotta start somewhere

Listen up, sometimes you gotta sweep that negativity away!

[Ensemble]
Yeah!

[Siramay]
Some people's road to fame
Begin on streets that have no name
It doesn't have to hold ya back
Once you're movin' on that track
Don't be confined to it
If you put your mind to it
You can always get your way
If you're willin' just to sweat your way
Don't give me the medial
Do the best you can
Remain congenial
And someday

[ALL]
you'll be the man!

[Siramay, (Ensemble)]
But you gotta start somewhere
(Gotta start somewhere)
You gotta start somewhere
(Gotta start somewhere)
And make yourself useful
Or you're never gonna get there
(Never gonna get there)
Once you get movin'
You'll find some way somehow
And it-

[ALL]
might as well be right here right now
Come on boy!

[Siramay, (Ensemble)]
You gotta start somewhere
(Gotta start somewhere)
You gotta start somewhere
(Gotta start somewhere)
You gotta get goin' (You're never)
Or you're never gonna get there
(Never gonna get there)
Once you get movin'
You'll find some way somehow
And it

[ALL]
might as well be right here, right now!
Come on boy!

[SIRAMAY]
DANCE BREAK!

Then siramay starts dancing

Come on dance with me Hajime

[HAJIME]
what!?
Why would I dance with you?

[SIRAMAY]
what did I just say about do nothings?
come on Hajime let out all your pent-up emotions the best way possible
DANCE.

And with that Hajime let go of his inhibitions and started to dance

[SIRAMAY]
yeah!
there you go!

Then siramay started to dance with him

[SIRAMAY]
who says you can't be the ultimate dancer!?

Keep moving and a-groovin'
It's honest state of mind
As long as you're improvin'
You won't feel left behind

[Siramay, (Ensemble)]
But you gotta start somewhere
(You gotta start somewhere)
You gotta start somewhere
(You gotta start somewhere)
Movin' or you'll
(Never, never, never, no)
Never get there (Yeah!)
Once you get movin'
You'll find some way somehow
(You'll find some way somehow)
And it might as well be right here right now
(Come on, come on boy!)
Might as well be right here
(You gotta start somewhere)
You gotta start somewhere
(You gotta start right now)
(You gotta start somewhere)
You gotta start somewhere
(You gotta start right now)
(And you'll be the man!)
Heeee-yeaaah!

[ALL]
YOU'LL BE THE MAN!

Siramay: … look I'm sorry if you thought I wasn't taking things seriously I really do care about you guys so from here on I'm going to try my best to control what I say and take things more seriously the last thing I'd want is to upset you guys even if I already did that.

Hajime: you mean that?

Siramay: with all my heart Mr. jime

Hajime: …you're alright muse.

Siramay: you mean that!? YEAAAHHOOOOOO
