Fate/Ascension-RWBY/Fate crossover (MS)

The 8th holy grail war is about to begin as the magi summon their servants.
Y/N Songbird a 21 year old blonde female whose long hair goes to her shoulders in a ponytail.
When she was younger she walked upon a group of males harassing a female who was weeping openly.
She was going to walk away slowly to get help until the male struck the women across the face after he groped her.
This spurred her into action as she took the knife she held always on her toward the throat of the man.
The man chuckled as he easily disarmed Y/N and beat her bloody before leaving her in the alley.
She eventually regained consciousness bloody and sore with the woman nowhere in sight.
After painfully walking home, you wash the blood off your now sore body before turning on the TV to the news station to find out the girl was murdered by those people.
At that time you went to London to train in the Clock Tower to attain magic power from her once dormant magical circuits.
After years of training she returns to the states to Detroit at the urging of the headmaster at the clocktower to enter the Grail war in Detroit.
