この勇者が俺TUEEEくせに慎重すぎる 2

[DeepL Translation - needs review] Volume 1 Introduction: Rista, a bad goddess, has been put in charge of saving the world in a very hard mode. She summons a hero, Seiya, who has outstanding status but is unbelievably cautious!　This adventure tale of a brave man who takes on slimes with firepower that leaves not a speck of dust in its wake, is about to begin!
