Borghild.

The next morning, after spending their nights at the inn, the duo quickly ate and took off.
Following the lead given by the old lady, they began navigating the difficult maze that is the city. The old tavern is pretty far away from the main roads, so it's harder to find, especially with how massive this city is. They maybe wasted a couple hours of their day. By the time they finally found that damned tavern, the sun was already high up there.

Jeffrey: "I really hope this pays off."
Saito: "Same."

Walking in, the smell of rotten wood reaches their noses.
The place was poorly lit with a couple figures sitting at different tables.
There's not a sound. Nobody talking. Almost feels dead.
They glance at each other, heading toward the bar.

The man behind the counter gives them a look.
"Hm?"

Saito: "We're looking for adventurers."
The man's attention goes down to his patch, showcasing his champion role in the military.
"What for?"
Saito: "To hunt the demon king."

A figure nearby glances at them, but looks away.
"If that's really what you want to do, you can ask him."

He points at a table. A lone smaller man is seated there, drinking beer.
Jeffrey's face goes wide, pulling onto Saito's shirt. He gets closer, murmuring.

"Saito! That's a dwarf!"

He rolls his eyes. You got what you wanted at least. 
"Thank you."
For the information, the leader leaves a coin on the table, walking up to the dwarf.

Not to be impolite, Saito gets closer, pulling on a chair.
"Can I sit here?"
The man gives him a look, then ignores him.

Since he wasn't told no, he sits down. Jeff stays up, standing right before him, keeping an eye on their surroundings.

He takes his time, thinking about how to word himself. He clearly doesn't seem intent on talking much, so he has to be convincing.

"I'm Saito. I'm a champion from the military, but I've been given freedom to travel around.  I'm on a quest to create a group of adventurers ready to follow me down to hell. I want to kill the Demon King. I don't know you, but my gut feeling tells me you're very much capable. Would you consider traveling with us."

The dwarf lift his eyes from his drink, glaring at them. It's as if he's trying to read their intentions.
"You're not the first one making outlandish claims of trying to hunt that demon. I don't care about your rank. I've seen people above you give up because they couldn't find him or because they weren't strong enough. Spouting nonsense like that won't bring you anywhere."

Ah, so that's what it is. People have left him disappointed so often he gave up.
"I assume giving you my word wouldn't be enough. What can I do to convince you I mean it?"

The dwarf raises his eyebrows, now more attentive.
"Why are you after the demon?"

If he starts talking about god, he'll probably lose the dwarf's attention. Nobody would believe that. Being from another world is one thing. Being on a quest from god is much less believable thing.
He has inquired about the Demon King in his free time before. He asked what the King did. People looked upset he even asked, claiming the Demon King wiped most of their Kingdom on a whim.
There wasn't any reason to it. But there wasn't any for the werewolf either. Nor for Vestris starting to kill all travellers on sight. It's possible he's not even responsible for it. It could very well be yet another ploy from god to seek entertainment. 

"I want answers. I want to know for sure what really happened."
"Huh. Don't you have history books for that?"
"Records don't always speak truth. The victor chooses what the truth is."

Jeff notices something moving in the corner of his eyes. As he turns around, the girl standing further, a cloak over her head, quickly looks away, avoiding his gaze.
(That girl is listening.)

"Aren't you wise for your age?"
"I've been told that before."

The dwarf smiles a little.
"So you'll do whatever I ask for you to show your dedication?"
"Sure. Name it."
"There's a dragon I wanted you to kill."

Jeff's attention quickly snaps back to the table.
"Sorry but the hell is happening now?"
Saito: "Dragon hunt"
Jeff: "Hell naw."

Oh don't be like that. I'm sure it'll be fun.
While he's not exactly excited at the idea of fighting a dragon, a mythical being, he really wants to see one. A real dragon. He's only seen depictions of them on screens or in books, but never physically. 

Saito: "Where's that dragon?"
"You're fine with that?"
Saito: "Yeah."
Jeff: "Saito pleasee."

"It seems I'm talking to a man. Nice meeting you. My name's Borghild."
Saito: "Nice to meet your Borghild."
Jeff: "I'm Jeff."

Saito chuckles but holds it in. Whenever Jeff says it that way, he can't help but remember memes he's seen online. He's so genuine, but that's what makes it funny. He'll never know. Even if he did, he wouldn't understand.

Borghild: "The dragon you're hunting is great white dragon. I was originally born for the sole purpose of killing it for my people. I've dedicated my life to training, just for that moment. Yet, when the moment came, I failed. I didn't have the strength it took to defeat the beast. As a result, my home exiled me. I failed them, so I have no right to return. I don't want the dragon dead so I can return. I have no intention of returning. I just want to the fulfilment of knowing the dragon is dead."

That's deep. Genuinely deep. Living and spending your entire life to train for a single fight, just to fail, sounds pretty crushing. Anyone would get depressed and lost after that.

Saito: "Do you want to come with us?"
Borghild: "Yes. I want to see the dragon die from my own eyes. 

The hero nods. If Borghild can have his peace, then that's what matters.
Saito: "I assume you use a hammer?"

A very common weapon for a dwarf.

Borghild: "Yes. I also use attack creation magic using ice."

Jeffrey looks over Saito's shoulder, stunned.
He has never heard of a dwarf using magic of his entire life.

Meanwhile, Saito simply sees it as natural.
(I guess dwarves have access to magic here.)

Saito: "Welcome aboard then. How far is the dragon from here."
Borghild: "Maybe a week worth of travel."

Oh. Chloe's going to be pissed.
He sighs.

Saito: "Okay, so be it. We'll travel a week out to kill your dragon."
The exiled reaches for his drink, finishing it in one large gulp.
He then extends his hand for Saito, offering a handshake.
The young man accepts his handshake, sealing their deal on it.

Jeffrey: "So we're actually doing this dragon bit?"
