Mato:

[Proud and Excited]  {context: an excerpt from Mato's dialogue shortly after meeting him}  No, don't speak a word. I, Nailmaster Mato, who was taught the Art of the Nail by the Great Nailsage himself, hereby accept you as my pupil! Let us begin the lesson immediately!

[Calm to gradually Brooding, then catches himself and returns back to Calm]  That Nail Art, the Dash Slash... learnt from my brother Oro, was it not? So he is still alive then. Hm. I still haven't forgotten what he owes me and I never will. Oh, I'm sorry. I shouldn't bother you with such things. I'm happy that you were able to train under another Nailmaster and grow stronger, my pupil.

Sheo:

[Relaxed]  {context: Sheo introduces himself to the Knight}  I am Sheo, and in a previous life I was a Nailmaster. Yes, the only thing that drove me was becoming stronger and honing my skills with a nail. I imagined it was my one calling in life, but that feeling faded over time. Now I seek a new calling, something that speaks to my soul and compels me forward.

Oro:

[Cold and Harsh]  {context: Oro offers to teach the Knight a nail art, but for a large fee}  It is the law of the Great Nailsage that I must pass down my teachings to those who are worthy. But no law forbids me from exacting a payment for my time. If you truly wish to train under me, prove it with Geo!

(inner monologue)  [Pondering, Slight Longing with a hint of Sadness]  {context: Oro thinking to himself}  Brother Mato, in your lonely home at the top of the world... do you still think of me as an enemy? In the future, if you will listen... I will tell you why I chose to tread this path.
