Nishuume Boukensha wa Kakushi Class "Juuryoku Tsukai" de Saikyou Omezasu

A few years prior, extra-dimensional beings invaded our world, forcing humans with unique abilities and expertise to combat them. Ikoma inadvertently became a “thief” and eventually achieved S-class adventurer status. However, his skills dwindled; causing him to lose his confidence. During a violent dragon attack on Ikoma, he valiantly fought but suffered fatal injuries. Remarkably, using his “thief” skills, Ikoma successfully stole a valuable artefact that allowed him to time travel. Returning to the past ten years earlier, he utilized his memories and experience to gain the exclusive “gravity user” abilities, intending to be the most respected adventurer this time around.
