Until I, a Fallen Nobleman, Was Called the Great Sage With My Hazure(?) Skill "Super Jack-of-All-Trades"

Hideo Mikado, who died in an accident, was reincarnated in another world as Lars Irving, the second son of a fallen aristocrat. Mikado was not loved by his family in his previous life, but in this life and world he was doted on by his parents and older brother and lived happily. He was criticized for his "super jack-of-all-trades" skill, which he received at the age of 5, as a "failure skill," but his family doesn't care and he lives a carefree life. One day, he learns that his father was a former feudal lord. As he continued to investigate, Lars suspected that the current lord's trap had ruined his father, and he began to take action to return his parents former title. The "super jack-of-all-trades" skill, which was thought to be a failure skill, turned out to be a cheat skill, and Lars was embroiled in a big incident. The struggle of the fallen noble who strive to solve the case with the failure skill "super jack-of-all-trades" now begins!
