After being betrayed by Blake on the train, her younger brother Y/N was taken prisoner by Atlas. Experimented on by a mad doctor, he becomes the first ever human/Faunus to survive the Aura/Dust Integration Experiment, which earns him the revolutionary moniker of The White Fangs Sword. Two years later, he reunites with Blake at the shipping dock and his story begins to get a lot more convoluted. What will happen when he finds himself captured at Beacon after another betrayal and how will he escape?!

Y/n Was A Little Boy Who was Thrown away From His Family In The street but then Summer Rose found him and Took him in to her Family, Y/n Thought it will be nice to finally have a family again but He Thought Wrong Summer, Tai, Yang, Raven will always Abused Him and Ruby and Qrow will always take care of him, Y/n has enough and Escape from the House so he was Given Freedom That day guys this is my Second Male Reader x RWBY hope you all like it -Kousei kasai

When she got with Tai, (y/n) Rose was gone. Took off without a trace. He comes back to Vale twice, one time to see her, and one time to find leads to bring her home.

You were born the son of Taiyang & Female Qrow, grew up unloved. At a young age you left a broken home to build a new life for yourself. Even went on to become successful, but then Ozpin called. One day you are called to Beacon, you think Ozpin is trying to enroll you...again. But it's really to reunited you with your abusive family, see how it goes. You are middle child, just a month younger than Yang. Ruby & Yang are both your half sisters. Summer is still alive, Raven is still around. So basically Tai went with the harem rout with his team. I originally meant for this to be a multiple chapter story, but when I realize I couldn't I chose to do a super long one shot instead. I always wanted to write my own neglected male reader story.
