After reaching Bar Rank 3 due to high sales, you will unlock a series of dialogues that unlock many new areas- and a new party member.
Kamerina: The store is gaining popularity! Great job Siela!
Siela: Well, yeah for now it is but we still have a load of problems Kamerina!
Siela: Our menu lacks variety. I need different kinds of ingredients!
Kamerina: Maybe you can ask Fred?
Siela: I feel like I depend on him too much.
Kamerina: I’m sure he doesn’t mind.
The game then cuts to the item shop.
Siela: ...so that’s why I’m here. I need different kinds of ingredients!
Fred: Say, the magic word Siela!
Siela: Huh? Pardon me?
Fred: Never mind... So you need something different, huh?
Fred:.....
Fred: Do you know about the small fishing village? The Port City of Lar.
Siela: No
Fred: I’m not surprised. It’s small. Nowadays, peddlers don’t even go.
Siela: What about it?
Fred: Well, I don’t know, I just thought of Peddlers from Lar that don’t come here any more.
Fred: That's why we don’t get much access to seafood.
Siela: Ahh... I see, maybe I should find out why peddlers stopped coming from Lar.
The conversation continues when you go back to the bar. It is reccomended that you do so right away in case you would like to use your new party member that you meet in the next dialogue, Alter the Drunk.
