I don't know if someone has translate this already but i wanted to translate Yamato's part anyways.
Yamato: You were always willing to kill me!!
Kaidou: Yeah... that's right. This is not a family quarrel... If you are going to carry Oden's name then be prepared for a "War". This is not a game, Yamato!!
Yamato: Is it a crime to admire him!? I like Oden!!
**Flashback**
Fodder: Kaidou-san, the Oni princess has been in a rampage for a week!
Kaidou: !?
Yamato: I'm Oden!! Take off these chains father!! I'm Oden!! Kouzuki Oden!!
Kaidou: ....
Yamato: I'm... *huff huff* Oden!! huff huff
Kaidou: Yamato... Did you do this...?
Yamato: Dunno... They just collapsed on their own. I'm hungry... i'm about to die...!! Give me food...
Kaidou: "Haoushoku" huh, you are promising... but if you are going to call yourself "Oden" then die, Yamato
Yamato: EEEHHHHH!?
Kaidou: Cool down inside the cavern! I'll give you one month
Fodder: Eh!? 1 month!? She is going to die!! Also, there are violent samurais imprisoned inside!
Yamato: Waaah! Wait!! Why do you leave me in this dark place!!
Kaidou: Great swordsmans from "Wano Kuni", it will be the same for you all...!! If you become part of my "military strength" i'll let you out. If you change your mind shout to the air hole in the ceiling. You haven't eat for a few days now right? I'll make someone carry food here...!! But just enough for 1 person. You will also need weapons for this, right?
Yamato: Eh!? Father....!? I'm your son! They obviously hold a grudge on me too!! I'm going to get killed!!
Kaidou: Aren't you "Oden"?
Yamato: !! (I'm Oden but... I'm also the son of Kaidou who killed Oden... I know that the samurais hate me too at least...! He is planning to make us kill each other to get the food...! No, but before that, they are going to kill me!!)
Samurai1: Eat
Yamato: Eh!?
Samurai1: Samurais never get hungry
Yamato: Eh!? Really? ...! I'm hungry...! (The samurais are incredible, they don't get hungry!?)
Ushimaru: Eat... You've been born in a very awful family...
Yamato: Thank you very much Samurai...!! I'll never forget this meal...!!! Hey.......!! Can i becom a samurai... even if i get hungry...? I...!!
Ushimaru: You are "Kouzuki Oden", right? We hear it...!! We also love that man
Yamato: Eh... Were you friends...? What's your... name?
A certain someone: The name of a samurai who lost huh... Just call me "a certain someone", fufu...
Yamato: ... I want to read this "journal" but there are a lot of difficult words
Samurai2: Oden's... logbook!?
---
A certain someone: Weeell... 10 days have passed... Yamato... Your father... Is really going to let his own child die...?
Samurai 2 and 3: ....
A certain someone: At this rate, we will not be able to witness the fight that Oden said that will happen in 20 years...
Yamato: I'... Fight alongside "Wano Kuni"... I'll sail to sea and become, more... more... stronger...!
Samurai2: That's reassuring... Then we will participate in the future fight by "not letting you die" here. We can't wait for 20 years...!!
Yamato: Samurai-san!! If you do that father will...!
Samurai2: We don't want to die from prostation!! We were never going to give in from the start!!
Fodders: Kaidou-samaaaaaa!!! The gate of the celestial rock cave has been broken!!!
Yamato: Even i have, people who believed in me!! People who approved me!! Why do you steal my freedom!? Why did you steal Wano Kuni's freedom!?
Kaidou: The world doesn't work by answering question by question!!! You brat!!
Kaidou&Yamato. Raimei Hakkei!!
