(aaaaand the same text repeats backwards in the next panel.  I'm guessing this is Saitou's interesting little ability at work.  I'm not gonna spoil what happens at Aburanokouji, lol.)
Man: ...Saitou-taichou!
Man: How have you been, Captain?
Saitou: I've just recieved orders from the Kyokuchou for a mission at the Tenman-ya Inn.  
(Note: The Tenman-ya incident occured about 3 weeks after Aburanokouji.  Some Shinsengumi were guarding an official and they got attacked by Ryoma's men.  Saitou was wounded there.)
Saitou: I want the Third Division on standby at headquarters.
Men: Yes, sir.
Saitou: ......

SFX: *sneaking noise*
Saitou: Did you have some business with me?
Tetsu: Eeep!!
Tetsu: I... uhh...
Tetsu: Yeah, kind of...
Tetsu: I know you were ordered to leave with Itou's group...
Tetsu: And it you're business what you choose to do...
Saitou: ......
Tetsu: But you should hear the stuff people are saying about you!  Can't I set those assholes straight?
Saitou: ......

Tetsu: Okay, I know it's probably what you want 'cuz it's a secret mission and all...
Testu: But the way they talk about you really pisses me off...
Saitou: .....
Tetsu: I... uh...
Tetsu: I just...
Saitou: You just can't ignore it?
Tetsu: ......yeah.
Saitou: No, I understand what you mean.
Tetsu: Huh?  But I don't even know what I'm talking about...
Tetsu: You sure you're okay, Saitou-san?
Saitou: You don't...
Saitou: Have to apologise...
Saitou: For what you think.
Tetsu: Huh!?
Tetsu: But...
Tetsu: Saitou-san, you're not a bad guy...
Saitou: If you're always apologising...
Saitou: Then...
Saitou: You're always losing something...

5
Tetsu: Hmm...
Tetsu: Sorry...
Tetsu: That's...
Tetsu: Not what I was expecting...
Tetsu: I thought all that stuff would bother you, but...
Tetsu: You don't have to worry about a thing!  You've been away for eight months, but...
Tetsu: This place is your home!  We're like a family, right?
Tetsu: Don't let those jerks get to you!
Saitou: No, really...
Saitou: I wasn't...
Tetsu: I don't blame you for looking depressed!!
Tetsu: But remember, "tomorrow is a new day!"
Tetsu: So don't be so gloomy!
Saitou: ......

6
Tetsu: Maybe things will start looking up for that Itou guy, too!
Tetsu: The Kyokuchou is gonna meet with him tomorrow!  Maybe...
Tetsu: Maybe they'll be friends again!
Tetsu: And then Toudou can come home too!

Text: [On the evening of the 18th, Itou Kashitarou was invited for a drink at the home of Kondou's mistress.]
Text: [On the surface, it appeared to be a talk towards renewed relations between the Shinsengumi and the Goryoueji.]  (If you've forgotten, Itou's group is called the Goryoueji, although sometimes you'll see them called the Koudaiji Party as well - the Goryoueji and the Shinsengumi were originally affiliated but obviously there was a bit of a falling out, lol, since Itou plotten to kill Kondou...)
Text: [But the real goal of the party was...]

8
Text: [To make Itou too intoxicated to fight.]
Itou: Ohohohoho.... ufufufufufu... *heart*
Itou: I think I've had a little bit too much to drink...
Itou: Ahahaha, oh no, it's been too long since I've had that much fun.
Itou: Next time, we'll have to get all of the Shinsengumi and all of the Goryoueji together and have a big party...
Kondou: Are you sure you're alright?  Maybe you should spend the night...
Itou: Ufufufufu, that's so like you, Kondou-san...
Itou: You're such a good liar~
Kondou: .....ah...
Itou: But sadly, I can't impose on you tonight.  My cute little Goryoueji boys are waiting for me~
Text: [It grew late, past midnight, and Itou came to a crossroads.]

Itou: ~~~~~~~*whistling*
Itou: ~~~~~~~*whistling*
Itou: ~~~~~~~*whistling*
Text: There, in the Aburakouji neighborhood of the seventh ward, the Shinsengumi were waiting for him.

10
Kondou: Itou Kashitarou... is he....
Kondou: ...dead?

11
Kondou: This sake was... too costly.
Kondou: ...There's no way we can explain our sins away.
Hijikata: Itou plotted against us first.
Hijikata: We're all sinners here.  We do what we have to do to survive.
Hijikata: In situations like this, you have to forget samurai honor.
Kondou: That's fine for you to say, Toshi...
Kondou: But you talk too much when you know you're wrong.
Kondou: You always...
Hijikata: What?
Hijikata: I always what?
Kondou: Forget it, it's nothing.
Kondou: I need a drink.
Kondou: I need to get so drunk...
Kondou: That I can't even think about this...

12
Souji: *COUGH COUGH COUGH*
Souji: *COUGH COUGH COUGH*
Souji: *COUGH COUGH*
Souji: *cough cough*
Susumu: Okita-san!!
Susumu: Just hold on...
Susumu: !!
Souji: ......
Souji: Ah... ah...
Souji: It's coming out...

13
Susumu: ...Just drink this hot water...
Souji: Yamazaki-san.
Souji: I'm fine, really.
Souji: You don't have to stay with me.
Susumu: No, I can't do that.  I'm a doctor...
Souji: I know, and that's why...
Souji: You should be in the medical office.  I'm sure that tonight...
Souji: There will be a lot of wounded people.
Susumu: I've been dreading this day...

14
Susumu: Here, there, everywhere...
Susumu: It all reeks of blood.
Assassin: Itou's assassination went exactly as planned.
Assassin: I left his body at Aburakouji.
Hijikata: Good.  Now how will we make sure his Goryoueji comrades go there?
Assassin: The local merchants have ties to the Koudaiji Party and report to them, so they even know when we get a new member.
Assassin: It's very likely that the Goryoueji are already moving.
Hijikata: Good.  You've done very well.
Hijikata: ...hm?
Hijikata: What's wrong, Yokokura?  Whatever it is, say it while you're here.
Assassin: Well...

15
Assassin: [The surprise attack was a success and Itou was fatally wounded by the first blow from my spear... but he didn't die right away.]
Assassin: [As I prepared to deliver the final blow, he moved to counter-attack me.]
Kondou: That's just like him...
Hijikata: Che...
Hijikata: Goddamned Hokushin Ittou Ryuu philosophy...
Hijikata: It's fine.  You've done well, and you're dismissed.
Assassin: Yes, sir.
Kondou: ...I wonder if they'll come...
Hijikata: They'll come.
Hijikata: We left his body lying in the road.  They'll come, exactly as we want them to.
Kondou: Toshi...

16
Kondou: What about... you know who...?
SFX: *purposeful walking*
Goryoueji Guy: There's no one here...
Goryoueji Guy: But this has to be the place...
Young Guy: There, in the crossroads!
Young Guy: In that palanquin...!?
Pretty Guy: Itou-sensei!!
Spiky Haired Guy: That's... really...
spiky Haired Guy: Sensei!
Pretty Guy: ......
Spiky Haired Guy: Sensei!
Spiky Haired Guy: Itou-sensei!!

17
Ponytail Guy: Show yourselves.
Ponytail Guy: If you're going to kill us, do it shamelessly.

18
Sano: As you wish.
Sano: We're the Shinsengumi.
Other Ponytail Guy: The motive of this attack is becoming clear...
Other Ponytail Guy: Hiding your shadows under a bloody new moon...

19
Other Ponytail Guy: Tonight is a poor stage for your perverse idea of "fidelity"...
Other Ponytail Guy: To leave a battered corpse in the street...
Sano: "Corpse"...?
Pretty Guy: Ah... ah...
Pretty GUy: Itou-sensei...
Pretty Guy: You told us that something like this would happen...
Pretty Guy: But I...
Pretty Guy: I never thought it would happen lke this...
Shinpachi: .....?
Pretty Guy: I... I never...

20
Pretty: ...Well this is going to be interesting.
Shinpachi: !!?
Shinsengumi Guys: What... when did they...?
Shinsengumi Guys: Captain!  We're surrounded!!
Shinsengumi Guys: What...?

21
Sano: Damn it... there's more of them!
Shinpachi: I can see that, Sano.  They're rounin...
Rounin: Muhahaha...
Shinpachi: It looks as if they're just hired mercenaries.
Sano: Break their circle and fight them one by one - concentrate on whatever guy is in front of you!!
Shinsengumi Guy: But Captain...
Sano: Unless you wanna die, you've gotta beat ten guys!
Shinsengumi Guy: Yes, sir!
Sano: Usually I like fighting against the odds, but I've got a bad feeling about this... oh well...
Pretty Guy: Ah, I see!
Pretty Guy: Well it's good that you don't care about the numbers!
Pretty Guy: Unless you just want to turn tail and run away, you know~
Sano: WHAT!?
Shinpachi: ......

22
Sano: Why the hell do you want to kill us!?
Shinpachi: [...!!?]
Shinpachi: Sano...
Sano: ?

23
Shinpachi: It's not us...
Shinpachi: ..They...
Shinpachi: They intend to destroy the Shinsengumi...!!!

24
Shinsengumi Guy: Kyokuchou!
Shinsengumi Guy: They're shooting flaming arrows from somewhere...!!
Shinsengumi Guy: Kondou-kyokuchou!!
Kondou: Stop panicking, you fool!!
Kondou: Wet your clothes and wake everyone!!
Kondou: I want half of our men fighting the fire, and the other half assembled in the main hall and ready for battle!!
Kondou: Just stay calm!!
Shinsengumi Guys: They've got the whole base surrounded!!
Hijikata: Get the sick and wounded to safety in the center of headquarters!!
Hijikata: As for everyone else, get every man who can move equipped and ready to defend the compound!!
Souji: *cough cough*
Susumu: Can you stand, Okita-san?

25
Souji: The fighting...
Souji: It's Itou's freinds coming for revenge, isn't it?
Susumu: No... it seemed that way on the surface at first...
Souji: ......
Susumu: Strange rounin have surrounded the headquarters.  It's now apparent that this was all planned.
Kondou: We already sent half our availible forces to Aburakouji!
Kondou: There are already one hundred attackers... maybe if we called them back...
Hijikata: We need reinforcements at Aburakouji.
Hijikata: Kondou-san, you're needed here.
Hijikata: If anything happens to me, you have to take care of everyone.

26
Souji: Hijikata-san, I'm going too...
Hijikata: Souji!
Susumu: Okita-san!  In that condition, you can't!
Susumu: We have to get you to safety...!
Hijikata: Kondou-san... Yamazaki-kun...
Hijikata: Let him do what he needs to do.

27
Shinsengumi Guy: Fukuchou!  The fires are almost out!!
Hijikata: The flaming arrows are less of a threat now, so more men can fight!!
Hijikata: Defend the front gates with spears and guns!
Shinsengumi Guy: Fukuchou!!
Shinsengumi Guy: Ah....
Shinsengumi Guy: ......
Shinsengumi Guy: Ah... ahh...

28
Itou: Ooh, you look so surprised... it's cute...
Itou: I wanted to see that face...
Itou: So...
Itou: I thought I'd let you try to kill me again~
Hijikata: ...Itou...!!
