From Lyrics - Shuumatsu Nani Shitemasu ka? belongs to the anime Shuumatsu Nani Shitemasu ka?, take a look at the argument:

Willem Kmetsch, driven by an unwavering resolve, fearlessly abandons his loved ones to confront an enigmatic monstrosity that plagues the realm. Yet, despite emerging triumphant from the perilous encounter, he finds himself encased in icy slumber. Little does he know that during his frozen exile, a nefarious breed known as the "Beasts" emerge from the depths, wreaking havoc upon humanity, threatening its very existence. Awakening after a grueling five centuries, Willem discovers he is the lone survivor of his species, witnessing the decimation of his kindred. In an attempt to preserve what remains, Willem seeks sanctuary alongside other surviving races on ethereal floating islands, while mortal terror courses through their veins at the mere thought of the Beasts lurking below. Bereft of companionship, Willem leads a solitary existence, toiling away at menial tasks to sustain himself. However, his mundane routine takes an unexpected turn when he assumes the role of caretaker for a clandestine arsenal. To his astonishment, this arsenal consists of a group of extraordinary and exceptionally young beings, known as Leprechauns. Deceptively resembling humans, their very essence is intertwined with the concept of self-sacrifice, deeming themselves as formidable weapons for the relentless war against the Beasts. Among these enigmatic individuals, Chtholly Nota Seniorious shines with her unwavering determination and readiness to offer up her own life in order to forge a path towards victory and tranquility. Willem, in a profound twist of fate, assumes the role of a nurturing mentor to these young Leprechauns, showering them with tender care and support. Formerly a valiant warrior fighting courageously on the frontlines of combat, his purpose now lies in earnestly yearning for the safe return of those stepping into the jaws of the monstrous adversaries that decimated his brethren.
