The last chapter of the Okita-Hijikata-Mitsuba backstory arc. Chapter 132, to be precise :O
Chapters 129-131 here. Chapter 132
(scene starts with Hijikata by the docks, and he's basically fighting still completely by himself :x He's holding up, but bareeeelllly. He got shot in his right knee. He then falls, and is surrounded by a group of people with swords :x)
Hijikata: *INSERT BATTLE CRY HERE THAT I DON'T FEEL LIKE TRANSLATING BECAUSE THE TRANSLATION SOUNDS WEIRD XD;;; ...but it's basically like a scream. OHHHHHHHHH. ...Yeah.*
Random guy: What's going on, Kuraba-dono? I thought you said we had these dogs of the Bakufu under control. Who is that man?
Kura: That's Shinsengumi's Demon Vice-Commander Hijikata Toushirou. Once you've been targeted by him, it would be troublesome and he's not easy to shake off.
Kura: ...But no. There should've been back-up arriving by now. (referring to Shinsengumi)
Random guy: Then, why's he fighting by himself?
Kura(? one of the bad guys): If that's the case....
Kura: Just make sure he (referring to Hijikata) disappears.
(scene shifts to Mitsuba in the hospital)
Doctor: Her pulse is down, blood pressure is low....This is really bad.
Doctor: This is all we can do now.
(scene shifts yet again to Gintoki and Okita on the scooter, racing toward the docks)
Okita voice over: Aneue. I'm sorry. But I, I...
(scene shifts yet again. This time we see the Shinsengumi racing also toward the docks)
Kondo: GET OUT OF THE WAY! SHINSENGUMI!
Kondo: *thinking* Toushi, you bastard. Who in Shinsengumi would ever want Sougo to leave? We're all friends, aren't wee? Why do you always insist taking on every responsibility by yourself? Even when you know perfectly well you'd be the bad guy here.
Kondo: *still thinking* I understand, Toushi. That for Mitsuba's sake, you---
(scene shifts to Hijikata at the docks, currently limping and bleeding)
Hijikata: Tch. *surrounded by all of Kura's underlings*
Kura: What a pity. You know, Mitsuba will be really sad at losing an old friend.
Kura: I wanted to be on good terms with all of you, you know. If the Shinsengumi were to back us up, our business would be even more properous. And so, with that in mind, I asked around about Mitsuba, since after all, if we control her, Sougo would be easy to control, too. But who knew she'd be so sickly? And dying too. It's a pity.
Hijikata: So. You used her for that end.
Kura: Oh no. Of course I love her.
Kura: She would make my business prosperous. Every businessman would love that.
Kura: She's a pawn. A tool. But she's also damaged goods. So this is good enough for her. If anything, she should be thankful.
Hijikata: *thinks about Okita earlier saying how, he'd like his sister to feel at least a bit of happiness before she dies* Heh. I really don't have any right to criticize you. I've done countless cruel things. And here I am, about to kill her husband.
Kura: Very well said. No wonder they call you the Demon Vice-commander.
Hijikata: No, that's not exactly true. I just...
Hijikata: I just want for the woman that I love to be happy.
Hijikata: For a man like me, who lives by the sword, it's not possible for me to give her that. So I wanted her to move on with someone normal, and live out a normal and peaceful life.
Hijikata: That's all.
Kura: Is that so? It's no wonder that us regular people can never understand what you samurai are thinking.
Shinsengumi: ATTACK!!!! *and they rush in, lead by Kondo*
Kondo: LET'S GO!
Kura's underlings: SHINSENGUMI!!!!!
Kondo: TOUSHI!
Hijikata: *gets shot at from various directions* Oof--
Hijikata: *tries to dodge, but one of the bullets hit a gasoline barrel? And it explodes right next to Hijikata*
Kondo: TOUSHI!!!!!
(scene shifts to Kura in his car, racing away from the scene. Ah, that bastard)
Kura: Well. That was certainly a mistake. I guess you can't work with monkeys, after all.
Kura: Hurry up. We need to go to the hospital. Even though she's dying, she'll make for a good hostage.
Kura: ....!!!!!
Hijikata: *is on the roof of the car and stabs through said roof annnd impales Kura through the shoulder* YOU BASTARD!
Kura: WHAT ARE THE REST OF YOU GUYS DOING?!?!?! SHOOT HIM!
Random guy: *TRIES TO SHOOT! But is hit by Gintoki's wooden sword!*
Hijikata: ...!! YOU!
Gintoki: Don't worry. I'm only here to get the senbei crackers for her. *throws a pack at Hijikata*
Gintoki: Give them to her (referring to the crackers).
Gintoki: She'll be happy, I'm sure.
(annnnd we see Okita standing a little ways ahead of the car/gintoki/hijikata, with sword out and looking quite scary :O)
Hijikata: *jumps down from the car and stabs through the tires, along with Gintoki, to try to slow the car down for Okita*
Okita, remembering what his sister told him and Kondo and Hijikata, right before they leave for Edo, presumably: Don't get in trouble now, all of you. Remember to always follow what you believe, alright?
(annnnd Okita slashes through the car :O aha it got sliced in half XD .....and explodes)
(scene shifts over to the hospital; the Shinsengumi are all gathered there)
Okita: Aneue, I'm sorry. I'm not a good younger brother. In the end, I ended up taking away your chance at happiness. I'm sorry. I'm sorry.
Mitsuba: Sou-chan, don't worry about it. You've worked so hard. You're really strong.
Okita: I'm--I'm not strong at all. I'm--I'm...
Mitsuba: You've always stand by what you've chosen, and for that, I'm thankful. Hey, don't cry, now.
Mitsuba: When you guys were leaving, and I saw all of you off...I liked how I was able to see all of you. I really like all of you (it could be translated to love? depending on the context, so whichever you prefer). All of you are truly good people.
Mitsuba: And that's why, I'm glad--I'm blessed, and I'm proud to have you as my younger brother. You make me proud, Sou-chan... (....and her hand drops and....yeah)
Sougo: .....*is crying*
(scene shifts to Hijikata and Gintoki outside on a balcony. Hijikata's eating those spicy senbei crackers)
Hijikata: These really are spicy.
Hijikata: Too spicy. Shit, it's spicy enough to make me cry.
Hijikata: Too spicy.
Gintoki: ....*looks down at the cracker* ...Yeah. Too spicy.
