Saving 80,000 Gold in Another World for My Retirement

Eighteen-year-old Mitsuha possesses a youthful appearance and petite frame that frequently cause others to mistake her for a middle school student. Her life is shattered when a tragic accident claims both her parents and her older brother, leaving her entirely alone. Overwhelmed by grief, she fails her university entrance exams and finds herself paralyzed by uncertainty about whether to pursue higher education or enter the workforce. Compounding her distress, opportunistic individuals begin circling her family’s insurance payout, while mounting financial pressures—including daily living costs and home maintenance—threaten to consume what little stability she has left. Just as the weight of survival seems insurmountable, a mysterious entity grants Mitsuha an extraordinary gift: the power of "World Jumping," which allows her to travel freely between Earth and a parallel fantasy world. Armed with this miraculous ability, she devises an ambitious financial strategy to secure her future once and for all. By leveraging the unique opportunities available in both realms, Mitsuha resolves to accumulate one billion yen in each world, aiming for a combined retirement fund of two billion yen—the equivalent of eighty thousand gold coins.
