Well before diving into the movie itself, LA will say that the anime series was a guilty pleasure anime with deep lore concerning both it's stance of magic and it's characters with TONS fanservice sprinkled all over the place as well as it's stellar diverse tech poppy soundtrack...LA liked Trinity Seven even with it's forefront flaws of excessive fanservice, lackluster battles and the main protagonist being not so "likable" and highly perverted and not driving the plot forward than his harem are doing it for him. So did Trinity Seven Movie: Eternity Library to Alchemic Girl have the same impact?..well...
Trinity Seven Movie: Eternity Library to Alchemic Girl's plot is extremely bareboned even for an anime movie reaching 55 minutes BUT deducting the 5 minute recap of the anime series and 5 minutes from the credits, it's merely 45 MINUTES. The plot for the first half is introducing Lilim voiced by Rina Hidaka, Lililth's Grimoire taken human form and thinks Lilith and Arata are her mama and papa and the rest fo the Trinity Seven ogle at how cute Lilim is...THEN our main villain of the movie Lust Trinity voiced by Nobunaga Shimazaki attacks and Arata and the Trinity Seven has to defeat him...see what LA meant by this movie being too short. (On a side note, LA found Lust Trinity's rivalry to Arata to be similar to Issei Hyodou and Vali Lucifer's rivalry in Highschool DxD, heck the similarities goes even further as both rivalries have both characters having the same power (in a sense) duking it out AND even further than that, LA thought that Trinity Seven as a series was like a distant younger cousin of Highschool DxD what with both of it's main male protagonist being open-minded perverts along with it's excessive fanservice and diving into lore of it's world both series go to.)
If the movie does have it's strengths it's comes from it's characters and already established lore it had in it's anime series allowing for the characters to evolve both in terms of battle and character development in some sense thus more screentime to the Trinity Seven as well as growing Arata in the process of it all, the next is the fact that LA did say the anime series had lackluster battles, but Trinity Seven Movie: Eternity Library to Alchemic Girl battles were a step up from the anime series and although the battles are limited to say the very least, what battles were shown were pretty amazing even for Seven Arc Pictures who also did the anime series. Lastly is the the fact that the stellar soundtrack is back and although slightly remixed it's still the same soundtrack which was kinda made the series and to be back for the movie it was a given as well ALSO ZAQ singing the ED "Last Proof" only reinforced Trinity Seven's impressive soundtrack for the movie. Returning voice actors of this production was back with the new addition of Rina Hidaka as Lilim (in which her loli vocals were decent enough and not-as annoying) but LA's favourite voice actors easily goes to Nao Touyama as Lieselotte Sherlock and Ayane Sakura as Levi Kazama by sheer obligation of favourite character of the series (and movie) and best voice actor of the series respectively.
AAAAND here LA goes on ranting...
LA already pointed out how short this anime movie but like MANY anime movies it falls into the tired and for LA annoying trope of introducing a new character (Lilim) only for that character to disappear and probably never to be remembered again, LA said this during LA's Aoki Hagane no Arpeggio: Ars Nova Cadenza movie review but it just felt almost pointless in getting invested in Lilim as a character as a result and it's even more baffling in which Lilim is actually canon to the Trinity Seven manga (LA isn't completely sure about this statement, so anyone reading the manga can you PLEASE clarify if this is true or not). The one and only other small flaw LA found from the movie was that due to movie's length that the main villain Lust Trinity kinda gets taken rather quickly for a "White Demon Lord", hell his DRAGON took more of a fight!...
And no, if you think LA would get angry that Lilith as a character took most of the focus from the movie, then LA sees that as misplaced anger due to the waifu wars in Trinity Seven, Trinity Seven Movie: Eternity Library to Alchemic Girl's movie is focused Arata and Lilith even before the movie, the anime made it pretty clear it's a supporting harem with Lilith as the main girl (this from a person who watched the anime TWICE, once in Dub and has Lieselotte Sherlock as LA's favourite character from the series), thus the movie focusing on Lilith and Arata is a no brainer.
So, LA poised the question if Trinity Seven Movie: Eternity Library to Alchemic Girl had the same impact as it's anime series and to answer that question...by means LA thought it did but slightly better, though the movie did improve in some aspects (the battles and more lore to the Trinity Seven's magic etc) but had the same pitfalls and new hurdles that it clumsily went through (like the movie's length, Lilim as the new "movie-only-but not was canon in the manga?" character and the major villain himself), but nonetheless even with all this mind, the movie did improve and still continued from the anime series with a bit of sequel second season bait?. Trinity Seven Movie: Eternity Library to Alchemic Girl should be a definite for Trinity Seven fans but for the rest......don't hold your breathe expecting the movie to have improve drastically from the anime series.
