Since birth, Gamagoori Fuutaro (蒲郡 風太郎) has been destitute. During his childhood, his wasteful and abusive father drove the family into insurmountable debt before abandoning them, leaving Futaro and his ailing mother to fend for themselves. Unfortunately, without the necessary funds for medical treatment, Futaro's mother passed away. Consequently, he became fixated on wealth and was prepared to resort to any means to acquire it.
