Countless lives have been lost in the long and brutal struggle that followed.
Now, the last line of defense rests in the hands of the remaining girls.
Among them is Shirogane, a member of the elite Unit 81—one of the most dangerous active combat zones. With exceptional combat prowess, she has saved her comrades time and time again from the kaiju threat.

[h2] ほんとに本当に好きです [/h2] 4時間前後でクリア出来る疑似3Dシューティング × SF百合ノベル シューティングゲームとしても面白いですが、「ノベルパートが多め」と謳っている通り、シナリオの完成度やキャラクターの関係性の作り、およびそれらの魅せ方が巧いです。 日常パートを交えた意味深な前半部から、予想を超えて一気に畳みかけてくる怒涛の後半部まで、 通貫してキャラクターたちの描写に抜け目がなくクリアしたころには感情がぐちゃぐちゃになっていました。 百合要素が好きな人には特に刺さると思いますが、そうでなくても「敬愛を拗らせた嫉妬」や「抜け出せない依存心」、「表裏一体の依存と優しさ」「純粋な敬愛」が好きな人の感情も揺さぶると思います。 各章がキャラクターごとの視点によるオムニバス形式で進み、最後にはしっかり収束する点も綺麗でした。 BGMもサントラが出ていないのが不思議なくらい良く、演出としても巧く機能しておりストーリーの盛り上がりに貢献していました。 遊んで損することが無い、心に残る良作です。
it feels a bit more like a concept (as most things are) than a fully realized vision. I liked how you can get a feel for the characters personalities/mental states through their gameplay segments, I always find things like that really cool. I really loved the music & art for the most part, story got a bit too pedo baity for me near the end tho. There is a point when a young character gets aged up quite a bit but is still mentally a grade schooler for no other reason than to sexualize them, kinda turned me off to some of the characters near the end of the game & the ending in general. My recommendation is more neutral than positive as a result, so just be mindful
