Rougo ni Sonaete Isekai de 8-manmai no Kinka wo Tamemasu

An 18-year-old girl, small in stature and often mistaken for a younger child, faces sudden hardship after a tragic accident claims the lives of her parents and older brother, leaving her alone. Struggling with grief, she fails her university entrance exams and must navigate financial burdens, including living costs and home maintenance, while others seek to take advantage of her family’s insurance. Uncertain whether to pursue education or employment, she is suddenly granted the ability to travel between her world and another dimension by an unknown entity. Using this power, she devises a plan to accumulate 1 billion yen in each world, aiming to save a total of 2 billion yen—equivalent to 80,000 gold coins—for her future.
