Alone in this turbulent and backward world, the originally optimistic and cheerful girl gradually became unable to live her life as she wished. Until one day, she decided to look for the wealth left by her grandfather regardless of the danger. "The most dangerous situation is to die. Anyway, there is nothing worse. Maybe it would be better to die." With this thought in mind, she got on the old motorcycle left by her grandfather and embarked on a journey of seeking life or death.
