Yukashi Yuusha no Fukushuutan: Mizu wo Oyu ni suru Koto Shika Dekinai Yuusha dakedo, Subete wo Ubatta Omaera wo Korosu niwa Koitsu de Juubunda

A Hero is a singular, divine champion chosen by God and bestowed with a unique supernatural gift. Only one Hero can exist in the world at any given time, and a successor is anointed only after the current bearer passes away. In this generation, the mantle falls upon Kyrie, an ordinary village girl whose divine blessing proves to be underwhelming: she possesses nothing more than the ability to heat water to a boil. Tragedy strikes when her family and friends are brutally slaughtered, leaving Kyrie entirely alone and backed into a desperate corner. Stripped of everything she holds dear, the grieving girl is forced to confront those responsible for her unimaginable loss. Driven to the brink, Kyrie begins to uncover the terrifying true potential of her seemingly useless power. She realizes that boiling water is far more than a mundane trick—it is a lethal weapon capable of inflicting excruciating pain. With nothing left to lose, she channels her profound anguish into a relentless quest for vengeance, proving that her modest gift is more than sufficient to destroy the monsters who took everything from her.
