Regarding the villagers splashing each other with wine - it's most likely based on a real festival in Spain called the Haro Wine Festival, where everyone fills up various containers with wine and "attack" each other.
Kanata sees a "fish" figurine and reads the price as 10 yen and 25 sen. The sen is a subunit of yen (where 1 yen equals 100 sen) that, since 1953, is no longer in circulation.
The town of Seize is based on real world Cuenca, Spain.
(Kanata is apologizing to getting lost again the day before)
Kanata: Um... I-I'm very sorry about yesterday!
Rio: Damn right, you are.
Kanata: I-I'm sorry! But...
Rio: I'm kidding! But from now on, don't do stuff like that. Not for something as stupid as this bell. (she holds up the bell she is wearing)
(Kanata is playing a wake-up reveille, although it doesn't sound very good)
Old Woman: The girl they've got playing this morning isn't very good.
Kanata: Sometimes, getting lost means that something fun happens. But that's only when you meet someone new. It's no fun being alone.
(Rio is holding Kanata's stained and wet uniform after the festival)
Rio: Looks like you made quite the target... Couldn't you have dodged a little?
(Rio points at Kanata through the window and Kanata runs off)
Naomi: What's wrong, Rio?
Rio: (referring to Kanata) A kitten had too much fun at the fair, and it ran off in the wrong direction.
Naomi: Can't be helped... Cats always take their time getting places. That's why they're cute, you know.
Rio: If it were a stray, it'd be OK. But it's a domesticated cat.
Kanata: (referring to her trumpet) I can finally let you sing.
Sergeant: Odd to see a new recruit, now that the draft's over.You volunteered?
Kanata: Yes! I wanted to learn how to play music. I mean...
Sergeant: An honest girl... I like that! Good luck, kiddo!
Sergeant: If you're nice to the trumpeter, you can hear them sound the retreat better.
