However, his aspirations quickly shattered when he discovered that even as a hero, he wouldn’t be able to lead a carefree life. Faced with this realization, he made a swift decision to retreat and find solace in a peaceful existence within the corners of the city. But fate had different plans in store for him. Letinoa, a young girl chosen by the sacred sword to be a hero, sought out Jirei persistently, determined to recruit him into her party. Despite his initial intention of avoiding any further trouble, Jirei found himself unable to resist. To escape Letinoa’s persistent requests, he agreed to an escort mission to a neighboring country, thinking it would mark a farewell to Letinoa. However, to his surprise, Letinoa and her party were also assigned to the same mission. As if that wasn’t enough, Jirei’s inadvertently audacious actions drew the attention of those around him. How did he find himself in this situation? And so begins the tale of an unwittingly invincible fantasy—a story of a lazy yet formidable adventurer.
