One example could be 'Yamamoto Takuya'. 'Yamamoto' is a common family name which means 'base of the mountain'. It could imply that the family has some connection to a mountain area. 'Takuya' as a given name can mean 'high and far'. So the story could be that the family hoped the person would have high aspirations and be able to go far in life, just like the family's connection to the mountains which are tall and far - reaching.
One popular type of such fanfics could be the alternate universe ones. In these, Ruby having long hair might be part of a whole different world - perhaps a world where the Grimm are even more powerful and she has to use her long hair as a sort of distraction or even a weapon in some cases. It adds an interesting twist to the original RWBY concept.
I'm not entirely sure specifically about 'yakuza ishin' having a long story without more context. It could refer to the complex narrative in the Yakuza Ishin game, which might involve themes of loyalty, revenge, and the struggles within the Yakuza underworld. Maybe it's about a character's long journey filled with challenges and moral dilemmas.
Perhaps Ruby Rosario is an outcast in the vampire - infested world. She could be on a journey to find a place where she can be safe from the vampires. Along the way, she might meet other characters who either help or hinder her progress. Her story could be filled with twists and turns as she discovers more about the vampires and their motives.
Since I don't know the details of this 'long story' about Ruby, I can only say generally. Maybe start by identifying the key problem or goal in the story. If it's a story about Ruby trying to achieve something, like getting a job. You could say she started by preparing her resume, then went through interviews, and finally either got the job or not.
