This is an alternate RWBY universe where a counterpart of Jaune was created after the real one fell into the void. He doesn't remember the events of the volumes but now him and the others can be warned.
Summer, Glynda, and Cinder are Jaune's aunts in this one, making Jaune the cousin of Ruby Rose (on Summer's side), Oscar Pine (adopted by the Rose/Xiao-Long Family), and Neo (on Cinder's side).
Roman and Cinder are married while having Neo as their daughter.
Qrow and Summer are married too and Qrow is Ruby's father while they have adopted Oscar.
Whitley Schnne is now nicer and is in love with Penny.
Oscar, Whitley, Blade, and Bang are the male version of Team RWBY and younger brothers of them but Yin hates Yang, which the feeling is mutual because she sees her brothers as an immature monster, which is hypocritical since she's in it for the thrill of being a huntress.
Johann Arc and Sierra Arc are cousins of Jaune but they act more like older siblings.
Cardin's family is invited as well but his sister, mother, uncle, aunt, and male cousin don't act like him.
There are new students in this universe: Team BLUE and Team PRON from Beacon, Team ARC, Team DETA, and Team BACH from Atlas, Team DOOM and Team HOPE from Haven, and Team DAWN and Team SAND from Shade.
Team BLUE's only male member doesn't like his team because of how they treat him and one of them cheated on him for selfish reasons. He is only close to Team DOOM and Team DAWN because they support him but he also is friends with Ruby, Jaune, Velvet, Sun, Penny, and Mercury.
