: What exactly do you need help with, Nori?
: When the battles against Hahen, Hai, and Jikkousu were going on, I realized just how much I relied upon Ookami, and it worried me...
: Come on, Nori, get to the point!
: Saigai! Show some respect!
: No, Arasoi, it's alright. Anyways, what I'm trying to say is, I wish to train to become stronger, so that I can fight without Ookami.
: So how do you plan on training, and how exactly do you want us to help with the process?

: You humans, so persistent. If you really want to get me to go along with this, you, Takeko, and especially that faux-Shishi Toraji must prove yourselves to me!

: Jinsei, I'm sure Nori appreciates the notion, but no. I know- and I'm sure Nori does as well- that if she's to complete this training, she's not going to get a chance to take a breath.
: Nori, talk some sense into Toraji, will ya'?
: No, Jinsei, he's right, I can't stop if I intend to become stronger, whether or not my thighs burn, my mind throbs, and my cuts sting.

: Your parrying skills as well! I'm actually trying to match you, and you're putting up quite a good fight!
: Thank you, Yuzuki, and Yuudai! Your help is very useful, and without it, I probably wouldn't be improving by near as much!
: I must say, your stealth is admirable, Nori.
: You can say that again, Shogi!
: Yes, Nori, you're doing superbly! So... NOW can I bandage you up?
: She's become stronger, but she's not completely done with her training.
: That's right, Takeko, but I'm almost done. This last part of my training will be the hardest though. That being said, I'm going to give this final stretch all I've got!
