I’ve read through both parts now and I have to say it’s nice to have some “mental break” between stories before your head gets a little worn out. Probably an early-days thing. Nonetheless some question emerged. Some of them were instantly answered by reading @NicoleIsEnough’s post. So thank you for that! Also thank you to @2OC3aOdKgwSGlxfz as well; I didn’t quite understand the fox part. The others were:
In 金の輪
から at the end of a sentence
Shortly after the beginning of the story we have the sentence 「かつてこんなに美しく光る輪を見なかったからであります。」Does the から at the end roughly translate to our “since”? So “Since he had never seen such a beautifully shining ring”?
This と's structure
「けれど、いつまでもその少年の白い顔と、微笑とが太郎の目に残っていて、取れませんでした。」The provisional of this と comes right after it, right? This would be a little different from the English sentence structure as far as I can tell. Or does the condition that accompanies this と come before in an implicated way?
In 大きなかに
The title
Uh, what exactly does the title mean? “Big Crab”? Sorry if this is a dumb question but I really can’t figure it out. This is the curse of WaniKani and I don’t just say that because of the かに. 
I often get lost when words don’t have Kanji. Often - after thinking about it - I will be like “oh that word is written here!” which is funny. Also, I’d much rather have this problem instead of struggling with Kanji. So no regrets here.
いつもなら
Do we have “always” and a provisional here? If so, can it be taken as “Even though he always goes to sleep when the sun comes down (…)”? Sorry, I don’t really know how to map out the sentence for you. It’s about half into the story in relation to this week’s breakpoint.
