Since Britain was so likely for “Britaniya”, another real country seemed probable and, given the origin, that strongly suggested Japan. But I also thought that, given your demonstrated Japanese knowledge, you might have worked from “和wa”, as in “和製語waseigo”, etc.

No web searches. I didn’t even have to look at my notes. This conlang is working its way into my brain.

“AN–DOGE … one part … hey, One Piece, that’s something I’ve heard of! There was even a 「ワンピース」カフェ on the news earlier.”

I used Wikipedia to confirm a name connection (Monkey D. Luffy) to avoid Anilist and your gloss, so I can still have a go at deciphering the description later. (The shorter ones I’ve worked through already.)

Not past-ish so much as passive-ish.

I very nearly wrote “past/passive”, but I’ve been dancing around “j́eske” in things like “iḿej́eskenamed” as being a passive or perhaps (im)perfective indicator. This is territory where I don’t have a good map, though, so it just got ished instead.

I wonder why you got that temptation?

The soldier thing is a product of over-extrapolation from insufficient data/understanding. Starting from “yesǒynevńe”, I trimmed away “ye–vńe” as “the [noun] of them”, which leaves “sǒyne”. Pieces like “eyni” keep cropping up in terms of “human(s)”, “one(s)” maybe, with “yn” seemingly more consistent than either end. That left me wondering about “sǒ”, and there are two matches there: “sǒyrinskaviolent”, which has the following “y”; and “sǒnt́echanged-direction”.

So I was thinking along the lines of “their changed one”, “their violent one”. I hadn’t translated much then, nor looked at the hints, and—well—anime has its share of child soldiers being told to get in the robot, doesn’t it? My process for these puzzles involves looking for common pieces, but also some imagination and then seeing if those possibilities fit into other slots. Elsewhere there was a “yeransǒv Y*ye” and, remembering “ran” as a “without”-y component, I considered that as a “Y—'s peace/stillness”. There’s some potential for it all coming together, but not a great deal. And, once I had more to work on, it became much more unlikely.

How did you figure that out? I don’t think I’ve ever used the words for “festival” or “soon” in any previous quizzes.

I have better records? You gave “śeskesoon” in Spinzine, and “uŕava-festival-CONS” in YeĆapeyniv Ňátaňski (both part 3).

The good

• I’m pleased to have gotten “full” for “deňe” from “deňiḱihandful” and “HiḱeyHands” since I wasn’t sure how literal “handful” was and loss of “h” could have been significant rather than phonetic smoothing.
• “naruždet́ev” looked like “to write (up)on CONS” so “signed up CONS” seems like I was headed in broadly the right direction from “ruždet́adewas-written-by” (another passive that’s past-ish).

The bad

• I had yaŕǒvfathis problem" down as “this cycle/wheel/loop???” because of “yeŕǒv yǒsethe survival of the species” and “ŠaŕǒChariot” which had me thinking about cycles of life, wheels, etc.
• “ńeribviret́edethey were disheartened” looked like it might be related to “bviradied” but, still with maybe a fight involved, I was thinking too literally at that point.
• Based on “vafor”, “vaxeymistakes” had me thinking maybe “purposes” which I was trying to link to the full/thorough/difficult adventure.
• “giriḿefamous” and “yagiravthe-glory-CONS” were not helpful for “yegitáyne”, etc., and had me considering some scenarios in which the club becomes celebrities.
• “yedogiv yepekruňiyev Y*yethe tasks CONS the high school education CONS Yui” had me thinking “parts of Y*ye’s high schoolers”, i.e., “some of Yui’s fellow students”.

Hindsight is 20-20

• “bzet́ato-end” is obvious now, but linking “yebzevthe-edge-CONS” with “yabzexetavthe-former-empire-CONS” had been bothering me.
• I went back as far as “¿Kon sulej́eske so ｢mámagroya｣?What Does “Freedom of Criticism” Mean?” trying to work out “konxulet́eto-explain” but couldn’t decide on a verbing of “what”.

Yekaysulivye

• Should that be “yakaysulivya” or something else?
• Can “vurćtepractice” be thought of as “goodening”?

K-ON!

As before, I translated a few clues and then searched.

“gi(t)” and “sur” seemed to be key parts but I just couldn’t figure them out. However, the first line looked like it said that Y— is a carefree girl starting high school with a dream of being in a particular club, and that seemed somewhat narrowing.

I decided “šeras̋ulet́ede” meant “she is greeted” (by three others), based on “ras̋ulećkegreeting” and noticing “de” tacked on to verby-looking constructions glossed as past-ish.
I translated “tavfat́ot́e” as “made to remain”, based on “tavfat́ato-remain”, kot́eto-go-to, and “kot́ot́esummoned”, but didn’t think it’d be in the description word-for-word.
There was a temptation to call “yesǒynevńe” “their soldier” but that didn’t seem very likely.
It did appear that Y— learned somehow with the help of the others.
And “yakruňuŕa : śeska” looked like “the school festival is soon”.

So the search term I picked was “anilist anime girl high school club greeted school festival”. That put K-ON!—with its promising exclamation mark—in top spot, and the description matched what I was reasonably confident about.

I was thinking something like “recolours” for “moḱrit́e”, but I guess it’s more like “relights”?

Ichigo Mashimaro

I thought I’d translated as much of this as I could—and determined the genre—but “ogevmoney-CONS” added to “sint́iseeing” suggested “looking for money” for “sint́i oget́e”, and “naon/by” plus “yatvarsavthe-important-CONS” and “YaspinavThe-day-CONS” suggested something like “onlooking/observing important days”.

But the line that I had me wanting a “fat́—” gloss today was “Ariḱiv krayski fat́iv krayski suliv krayski.”

Which now looks like “[K] girls [k]-ily doing [k] things.” Could that be helpful without “k”? “Crazy”, à la “cray cray” seemed like something you’d avoid. “sakraskacarefree” made me think about the possibility of something like “caring”. But, since it was in quotes, I thought it might be a term known to anime folks, and a search for “anime girls doing things” immediately turned up “cute girls doing cute things” as a likely candidate. And searching “anilist cute girls doing cute things slice of life” put Ichigo Mashimaro as first result, complete with a snippet that read like my attempts at translation.

So cheating with Chika wasn’t necessary, just enough of a Rosetta Stone and a little subject knowledge.

Machikado Mazoku (The Demon Girl Next Door)

With “šazbat́eyhe-begins”, “yezbevthe-beginning-CONS”, “Xaydǒa-great-war”, and “YerokdǒvfeThis-psychological-war” added in, “ToFrom yazbav yaLanathe-world heTEMP yedǒv Une kotoversus Jese” looked like it described a war/battle since the start of the world between two things—perhaps concepts rather than named entities (because they weren’t obscured). The classic Good and Evil didn’t fit the previous glosses, though.

Adding in “zuraevil” and “eynivpeople-CONS” to “yǒynevthe-family-CONS Y**ǒ ňaTOPIC yezureyni” gives “Y**ǒ’s family are the evil people”.

Given the genre, I’d guess at the prefix to “a girl CONS” in “liňariḱev” as “magical”, not that it’s particularly useful elsewhere, even if I can see that she has the name M— and is a classmate of Y—.

Considering “moḱet́ato-restore”, “moḱiḱeto-reconstruct”, “udet́egained”, “virdavpower-CONS”, “kayeany”, "“dent́elost”, “iḿej́eskenamed”, and “sinj́eskeis-seen”, it would appear that “moḱudet́e virdev kaye denj́eske yǒynevšeher-family” means “to regain any powers lost by her family”.

I don’t know much anime though, so none of that was directly helpful to naming the series. But(!) I noticed “yaDim” in “yaDimdayǒvthe-Demon-King-CONS” in one of the new reveals, so I guessed there was something feminine and either demonic or monarchical in the title. Back to the Internet.

“magical girl anime regain family lost powers” didn’t give the answer, just a bunch of top lists, but one of those did have near the bottom “The Demon Girl Next Door”, which looked very promising. It mentioned “Light” and “Dark”—presumably ‘Une u Jese’—and it had Y— and M— character names. Again, the anilist description matched and, since you’d provided “yont́ieats”, ‘so šo’, suddenly “all-you-can-eat” looked really obvious.

You are going to have to deconstruct “pancakes”, though.

SHIROBAKO

Using the new glosses, it looks like a story of five girls who had made an animation and [something something] second animation together.

So I searched “anime series about girls make anime”, looked through a list of 13 series, and noticed one about five young women entering the animation industry. The anilist page for that one also used all-caps for the title, and had character names A—, S—, E—, M—, and M—.

The rest of the description seems to correlate (“ranwithout poĺa,a-book,” = “scriptless”), and following a chain of “SHIROBAKO” to “白shiro箱bako” to “white box” to “box/container CONS white” to “[something]V [something]” leaves me settled on this answer.

It’s a TV series about the daily lives of Ć**é, her twin sister N***ye, and her friends M*ǒ, M***ŕe, and A*é, involving befriending others and going to school? They’re probably all girls.
