OG 39 [RE: 39]
Yeah, this part was very difficult. I didn’t really get it after I read it the first time, but getting a question about it is a good excuse to think harder about it, haha.
I think the most important sentence here is this one, before the ones you quoted:
「カードらにさくらのことが伝わっとる」
「カードら」is “card” plus 「ら」, which is apparently a plural marker. So “cards.”
「伝わっとる」is a contraction of the ている form of 「伝わる」, meaning “to be conveyed” or “to be communicated/circulated/passed down.”
Frankly this was a hard word for me to understand. It looks like the ている form is used to mean something like “has been communicated and is currently known/understood.”
See native camp, where 「伝わっていますか」 is explained as “do you understand,” or perhaps more literally “Are you being communicated to (properly, such that you can understand me)?”
Also see reverso, where 「伝わっている」 is explained as “has been passed down,” or perhaps more literally “has been transmitted through the generations, and is currently still known by modern people."
With this as context, I think this:
「カードらにさくらのことが伝わっとる」
can be translated like this:
“The cards know about Sakura (because they have been informed about her in some way).”
Then the next sentence:
「さくらがカードあつめてるて」
would mean something like:
“(They specifically know/have been informed) about Sakura collecting cards.”
After that we have:
「風」が「伝達」や「情報」を表すカードでもある
I’d translate this as:
“The ‘Windy’ card also means “communication” and “information.”
So based on the meaning of the Windy card, Kero was able to interpret that the reason a card appeared that looks like Sakura is that the cards she hasn’t captured yet have learned that Sakura is capturing them, and have decided to launch attacks that specifically target her (in this case, by making Sakura look bad, maybe so that she gets in trouble and it’s harder for her to move around freely).
The explanation about the sword card goes into the next page, and the page after that is also relevant, so I’ll continue below.
OG 39-41 [RE:39-41]
The reason Kero starts talking about the sword card is to show how the cards are clearly going after Sakura specifically. Before, the cards were just doing whatever, but the sword card specifically went after Rika because Rika is Sakura’s friend, and that way it could attack Sakura directly.
(By the way, Kero says “your friend Rika was being controlled by the sword card” rather than that Rika was controlling the card. That’s because 操られて is te-form of 操られる, which is passive, and thus means “to be manipulated by.”)
Sakura counters that the Shadow card didn’t go after her directly, but Kero points out that it attacked in the store that her brother Touya works at. Sakura responds with shock that the cards may even know about her brother. Finally, Kero responds that they should use fortune telling to confirm why Shadow did what it did.
This time, instead of the Windy card, Sakura picks up the Sword card.
I still need more time to figure out Kero’s response to that one, but I’m sure that once again he’ll use the alternate meanings of the card to interpret something important!
