The protagonist, Yagami Reito, who has lived a life of constantly being unlucky, dies crushed by a steel beam that fell at a construction site. In the afterlife, he is told by a goddess that she will grant his unfulfilled wishes from his previous life, where he was not blessed. Desiring a peaceful life reminiscent of the protagonist described in a novel he briefly skimmed, he requests to be reincarnated to live such a life. However… “What is this skill called ‘Protagonist’s Blessing?” What is going on?” The goddess mistakenly used a light novel of the “strongest protagonist” genre as a reference for the desired “slow life,” where the protagonist unknowingly becomes invincible while wanting to lead a slow life. Due to this misunderstanding, the skill ‘Protagonist’s Blessing’ bestowed upon him in his reincarnation is a curse-like ability that grants him “superhuman abilities but also attracts various troubles” just by his presence. He had wished to live a slow life and decides to quietly resolve the troubles caused by “the protagonist’s blessing” in order to create a world where he can peacefully live without any reservations. However, contrary to his intentions, he gradually gets entangled in a great conspiracy, while at the same time, legendary beasts and princesses of powerful nations start to admire him! This is a comedic 70% and serious 30% adventure tale about the strongest protagonist, who was reincarnated into another world with an unwanted ability, solving various problems to obtain a peaceful life.
