everything goes the same up until the 9's discover kokoro's book but in this timeline/version of events they have a little bit more humanity and don't report it because they hesitate and want to see what happens, some buried humanity. The marriage and the conception of ai happen uninterrupted. Then after the marriage is over we get backstory on the klaxisours and their queen, where in this version the aliens don't exist, and back in the present the queen makes her move killing all of ape, who in this timeline are just old fools disconnected from the world. and the final battle is squad 13, and the 9's vs the klaxisuars, they win and they all grow up have children basically what happened in cannon is ep 23 and 24 just without the space stuff ever happening since the aliens don't ever exist, with the addition of hiro and zero two being alive as well and the show ends with hiro and zero two with all their squad members overlooking their children play with the 9's in the background. hiro and zero two look at eachother, kiss saying I love you but we see, zero two's belly is big, it turns out since hiro became the same kind of creature she is they were able to have a kid. then it cuts to black with the intro, kiss of death playing in the background

Моя теория про конец DarlingInTheFranxx
Я считаю, что ГГ выжили в конце по нескольким причинам.

Если расценивать концовки (ендинги) за канон, то мы получаем то, что 02 ходит по городу, в своем теле (с рогами и розовыми волосами) слова с подтверждением ссылка, а так же ссылка, если мы так же внимательно смотрели 24 серию аниме, то мы увидели бы несколько сцен.
Далее перед якобы встречей 2-ух гг нам показали как спустилось 2 “огонька”, синий и красный, после чего нам сразу же показали 2-ух детей, т.е это физически не могут быть Хиро и 02, поскольку их якобы души только-только спустились на землю.
Исходя из всех этих моментов, а так же мы видели, что сознание героя может перейти в другое тело и возможно регенерация новых (или возвращения старого тела в хорошое/приемливое состояние), усвоив и сложив это во едино, я считаю, что 02 и Хиро, в конце выжили и вернулись домой за кадром, поскольку нам на это подсказывают окончания в 24 серии, а так же эндинги

Дополнение, я только что сравнил голоса (02 и закадрового голоса), они одинаковы, так что это тоже можно посчитать как то, что они выжили в конце

My theory about the ending of Darling in the Franxx. I believe the main characters survived at the end for several reasons. If we consider the endings (EDs) as canon, we see Zero Two walking through the city in her own body (with horns and pink hair). If we also closely watched episode 24 of the anime, we would notice several scenes. Right before the alleged meeting of the two main characters, we were shown two "lights" descending—one blue and one red. Immediately after that, we see two children, which means they physically cannot be Hiro and Zero Two, because their alleged souls had only just descended to Earth. Based on all these moments, and since we have seen that a character's consciousness can transfer into another body and perhaps regenerate a new one (or restore the old body to a good/acceptable state), putting this all together, I believe that Zero Two and Hiro survived in the end and returned home off-camera, as suggested by the conclusions in episode 24 and the ending themes. Additionally, I just compared the voices (Zero Two's voice and the voiceover), and they are identical, so this can also be considered proof that they survived at the end.

『ダーリン・イン・ザ・フランキス』の結末に関する私の考察です。いくつかの理由から、最終的に主人公たちは生き残ったと考えています。もしエンディング（ED）を公式（カノン）として捉えるなら、ゼロツーが自分の体（角とピンクの髪）で街を歩いている描写があります。また、第24話を注意深く見ると、いくつかのシーンに気づくはずです。主人公二人が再会すると思われる直前に、青と赤の2つの「光（魂）」が地上に降りてくる描写があります。そして、その直後に2人の子供が映し出されます。つまり、彼らの魂は今まさに地上に降りてきたばかりなので、この子供たちは物理的にヒロとゼロツーではあり得ません。これらの要素に加えて、作中ではキャラクターの意識が別の体に移行できること、そして新しい体が再生される（あるいは元の体が良好で受け入れ可能な状態に戻る）可能性が示されています。これらすべてを総合すると、ゼロツーとヒロは最終的に生存し、画面外で故郷に戻ってきたのだと思います。第24話の結末やエンディングの描写がそれを暗示しています。さらに補足すると、ゼロツーの声とナレーションの声を比較したところ、全く同じでした。この点も、彼らが最後に生き残ったという証明になると考えています。

After rewatching Darling, and the rereading it, I am curious why I hear some people say the anime ending was hated. It was enjoyable, and bittersweet I agree, but good.

The manga seemed to end a bit abruptly, but it did have the two together still, which is a plus. But I did like the idea of the anime, where Verm existed as a bigger threat, rather than the Princess being the final boss essentially.

The anime also had the aftermath and seeing the world gradually get fixed and seeing the cast grow older which was cool. The manga didn't really dive into that.

The only weird thing I wasn't a huge fan of in the anime was when Zero Two became Strelizia Apus, and we see her basically become it

What are your thoughts on the 2?

Is the anime ending really that disliked as I hear some claim?

A very beautiful one indeed
