Rud, known as the strongest tank in history, is a member of the Hero's Party, which frequently embarks on labyrinth raids. However, Rud's reason for participating runs deeper than mere enjoyment; his beloved sister's illness drives him to seek out the fabled wish-granting treasure thought to be hidden within these labyrinths. Despite his dedication, his skills are criticized by the arrogant hero, resulting in Rud's removal from the party following an unsuccessful raid attempt. With no alternative paths and no objectives left, Rud decides to return to his hometown where his sister awaits his return. During the trip, Rud rescues a girl from a monster attack. Remarkably, this girl possesses an uncommon ability known as "Appraisal," and it is through her talent that Rud uncovers the truth behind his own powerful, yet previously unknown skills. Armed with his impeccable defense and extraordinary abilities, Rud's journey as the strongest tank is just beginning!
