Putting his life on the line, Willem Kmetsch leaves his nearest and dearest behind and sets out to combat a mysterious creature, although he’s victorious, he’s left suspended in ice. It’s during his icy slumber that frightening creatures called”Beasts” emerge on the planet’s surface and undermine humanity’s existence. Willem awakens 500 decades afterwards, only to find himself the only survivor of his race since humanity is pumped out.Together with all the other living races, Willem takes refuge around the floating islands in the sky, living in dread of this Beasts below. 1 day, he’s tasked using a weapon storehouse caretaker. Even though they bear every similarity to individuals, they don’t have any respect for their lives, differentiating themselves as only weapons of warfare. One of them is Chtholly Nota Seniorious, who’s more than prepared to sacrifice herself if it means beating the Beasts and ensuring peace.Willem becomes something of a father figure for the youthful Leprechauns, seeing them lovingly and encouraging them in any way he could. Heonce fought bravely on the frontlines, can now only expect that the ones being delivered into combat return safely in the critters which ruined his type.
