Billionaire Girl

Takato Kei, a regular college student, takes on an unusual part-time job tutoring a young girl named Fujioka Yukari. Paid 10,000 yen per hour, he discovers that Yukari is not a typical student but a teenage day trader with a fortune of 170 billion yen. Despite her wealth and luxurious apartment, she appears lonely and self-conscious about her intense focus on the stock market, which she compares to an otaku hobby. Kei might be able to help her overcome her isolation and find something beyond financial success.
