Text: Chapter 25
Text: Rear Guard

Suzu: Look, sensei.
Suzu: The Shinsengumi headquarters looks like a beehive that's been shaken up.
Suzu: Doesn't it?
Suzu: How does it make you feel?
Saitou: ......

2
Suzu: Even if the outcome is the same, it's all that's lead up to it that makes it special... the feeling is completely different, isn't it?
Suzu: It feels good to be the antagonist...
Suzu: Don't you think so, too?
Suzu: It must be true, or you'd be with the Shinsengumi now...
Suzu: You've betrayed alllll of your little friends~
Suzu: Doesn't it feel wonderful to watch from up here?
Tetsu: [It's okay!]
Tetsu: [Just forget the bad stuff and live without regrets!]

All that Disjointed Background Text: [Maybe... you're some kind of ghost... it looks like... they'll be friends again... they're dead... Toudou will come back... did I kill him?... I don't know!... listen to me... the way we were five years ago... tomorrow... what we were just talking about... tomorrow, Itou... there's nothing I can do...]  (note: Yeah, none of that makes sense to me either.  Saitou's inner thoughts are kind of creepy.)
Saitou: [You...]
Tetsu: [Just try to smile and believe that things will get better!]
Suzu: So?
Suzu: How does it feel?

4
Thug: DIE!!
Kikuchi: Uwaaah!!
Shinpachi: Kikuchi!
Shinpachi: Get down!!
Thug: !?

5
Kikuchi: Nagakura-taichou!!
Shinpachi: ...Shit.
Shinpachi: You're the only one left... come on, let's go!
Kikuchi: Y... yes, sir!

6
Kikuchi: Ugh...
Shinsengumi Guy: !! Kikuchi!
Shinsengumi Guy: Are you alright!?
Sano: Shit, what's going on...
Sano: Is the base on fire?
Shinsengumi Guy: If it is, we can't go back there tonight.
Shinpachi: But we can't stay here at Aburakouji either.
Shinpachi: Somebody go on the roof and look for a clear way out.
Sano: Hey, you've got to be kidding, Shinpattsan!
Sano: This run-down place is completely surrounded.
Sano: Won't it be easier just to kill anybody who tries to get in?
Shinpachi: You're the one who's joking, Sano.
Shinpachi: We don't have enough men to hold out until morning.
Shinpachi: Those guys want us dead.

7
Shinpachi: If we escape down a narrow, winding street, I think we can lose them.
Shinpachi: Sano, make us an opening.
Shinpachi: I'll bring up the rear.
Sano: Hey... Shinpachi...
Wounded Guy: Taichou!!
Wounded Guy: I'm sorry, but I object!
Wounded Guy: Running away is against the honor of the samurai!!
Wounded Guy: We're soldiers who would give our lives to defend you!
Wounded Guy: I'll stay here and fight!
Wounded Guy: I am prepared to die!!

8
Wounded Guy: !!? *gets punched in the face*
Wouned Guy: What!?
Other Shinsengumi: Nagakura-taichou!?
Shinpachi: "Honor" and "rules" are part of the Shinsengumi!
Shinpachi: But if we die, the Shinsengumi dies too!!
Shinpachi: Rules aren't worth killing yourselves over!!
Shinpachi: Living to protect the Shinsengumi is more important than samurai pride!!
Shinpachi: Don't give your Kyokuchou and Fukuchou one more person to mourn!!

9
Wounded Guy: Taichou...
Dumb Looking Shinsengumi: Nagakura-sensei...
Shinpachi: I don't want to see...
Shinpachi: A single one of you die.

10
Sano: ...They'll be calling for us soon.
Shinpachi: Yeah.
Sano: Well this is gonna be fun.  Just promise me...
Sano: That you'll find some way to live.

11
Balding Thug: How's this?  How about we have some fun inside?
Scarface Thug: Why not?  The guys outside sure are!
Scarface Thug: I think we oughta kill all of those Aizu bastards.
Scarface Thug: Let's start with the sick and wounded ones.
Scarface Thug: Ah...
Scarface Thug: I found something for us to play with.

12
Souji: *lots of coughing*
Scarface Thug: Ooh, you poor thing, that looks like it must hurt!
Scarface Thug: But we'll make you feel allllll better~~!!

13
Souji: ...Filthy.
Souji: Filthy.
Souji: Filthy...
Souji: ......

14
no text, but Souji is insane and killing everything. 

15
SFX: *sticky footsteps*
Thugs: Aiiiieee!!  He's coming!!
Thugs: That must be Okita Souji!!
Thugs: You... you're supposed to be dead!!

16
Souji: *lots of coughing*

17
Thug: He...
Thug: He...
Thug: He's a ghost!!
Thug: Run!!
SFX: *some ninjaesque noise, I guess, as Susumu knifes some guys in the head*

18
Susumu: Okita-san.
Souji: ......
Susumu: Okita-san.
Souji: ......
Susumu: You can't go.

19
Souji: ...Please let me go.
Susumu: You can't go.  Please return to your room.
Souji: Please let me go.
Susumu: What do you think you can do with that body?
Souji: ......
Souji: Please let me go.
Souji: Let me go!
Souji: Let me go...!!

20
(note: Susumu stabs psycho!Souji in the neck to knock him out.)
Susumu: ...You ought to know your own limits.
Susumu: If you can live even one more day...
Susumu: I will force you to keep breathing...!


21
Sano: UWAAAAAAAAAAAAAAAAAAAAAAHHHHHHH!!!
Sano: Alright, it's clear, now let these chickens out of the coop!!!
That Dorky Guy from Itou's Group: Wow!!
Dorky Guy: Amazing!!  He's amazing!!

22
Dorky Guy: He's breaking through the third point easily!!
Dorky Guy: Eight, no, nine!!
That Underaged Boy from Itou's Group: ...More like six.
Man in Black: Well, whatever.
Man in Black: We're just here to watch.
Underaged Boy: That short guy is bringing up the rear, right?
Man in Black: ....The rear guard...
Underaged Boy: ?

23
Man in Black: The rear guard.
Man in Black: That's the rear guard...?

24
(note: Toudou comes out from the shadows behind Shinpachi, but Shinpachi notices him)
SFX: *creak*
SFX: *drip*

25
(note: Toudou draws his sword.)
SFX: *grab*
SFX: *swish*

26
(note: Toudou and Shinpachi face eachother.)
no text

27
(note: Toudou swings at shinpachi, who doesn't move.  Toudou intentionally misses and sticks his sword in the wall next to Shinpachi's head.)
Toudou: ......

28
Toudou: I can't do it, Shinpattsan.
Toudou: It's stuck.
Toudou: So am I dead now?
Shinpachi: ...I dunno, are you dead?
Toudou: Ah, you haven't changed.
Toudou: Always going easy on me.  That's my Shinpattsan.
Toudou: I guess you killed these guys, huh?
Shinpachi: ......

29
Shinpachi: This isn't an attack.
Shinpachi: I'm here alone.
Toudou: ...Oh.
Toudou: But I don't mind if you kill me.
Toudou: Well...
Toudou: Sano and the rest got out.
Toudou: But they're surrounded now.  Everything's all gone to hell.
Shinpachi: ......!
Toudou: I wish I had never left you and Sano.
Toudou: When I joined the Goryoueji, I thought I could separate myself from you.
Toudou: ...I never thought I see you like this.
Toudou: You should go.  It's dangerous.
Toudou: Come on, I know a safe way out.
Shinpachi: ....Hey.

30
Shinpachi: You knew all about this damned plot, and you didn't say a thing?
Shinpachi: You think I'm going to believe a word you say?
Toudou: ......
Toudou: Whatever.
Toudou: Do whatever you want, Shinpattsan.
