I was reading the forums & it just now occurred to me that Suzuha landed in Japan a day before with practically no plan & little knowledge of the world as she is stunned by in. In the section about Suzuha this quote hit me "Suzuha manages to acquire a MTB bike and a phone"
How else would someone with no money (as the story never makes mention of her bringing any) & little knowledge of the country at the time manage to buy a high end bike & phone?
