One possible plot could be that Ruby discovers Yamato in a strange new world or dimension within the RWBY universe. She has to figure out how to use it or control it while also facing the challenges that come with it, like other Grimm or villains being attracted to the power of Yamato.
Maybe Ruby is given Yamato by a mysterious figure. As she starts to use it, she realizes it has a connection to her Silver - eyed powers. This connection could either enhance her abilities or put her in danger as she has to learn to balance the power of Yamato with her own powers. And along the way, she has to deal with her friends' reactions to her new weapon and power - up.
In a fanfiction, Yamato could be a key to unlocking an ancient secret in the RWBY world. Ruby, being the curious and adventurous type, is the one who gets hold of it. She then embarks on a journey with her team to uncover the mystery behind Yamato. Along the journey, they face various obstacles and also learn more about the history of their world and how Yamato fits into it. This could involve battles, new character introductions, and lots of character development for Ruby and her team.
