Saving 80,000 Gold in Another World for my Retirement

After a sudden plunge off a cliff, Mitsuha Yamano awakens in an unfamiliar realm that closely resembles medieval Europe. Stranded in this fantasy world, she quickly faces the harsh realities of her new surroundings when a vicious pack of wolves nearly claims her life. However, during this desperate struggle for survival, she makes a startling discovery: she possesses the extraordinary ability to freely travel back and forth between Earth and this strange new land. Rather than simply trying to find her way home or embarking on a traditional heroic quest, Mitsuha approaches her situation with remarkable pragmatism. Recognizing the immense potential of moving seamlessly between two worlds, she decides to leverage this unique power for a singular, highly practical goal—securing her financial future. Her ultimate ambition is to accumulate eighty thousand gold coins, a fortune large enough to guarantee a comfortable retirement. What follows is a tale of clever schemes and calculated opportunism. Armed with modern knowledge from Earth and unrestricted access to both realms, Mitsuha sets out to exploit every available advantage. This is the story of her ambitious and unconventional journey to amass a small fortune, one shrewd venture at a time, ensuring her golden years are fully funded regardless of which world she ultimately chooses to inhabit.
