==Prologue: Introducing Y/N==
Everyone from Union was invited to hear about someone called Y/N.
Team RWBY and Rias' Peerage got excited.
(On a hill, an adorable, innocent, and cute young boy was looking at the sun while eating a chocolate ice cream cup.)
All girls said awe and saw him as their future husband.
"Y/N!" yelled the excited Team RWBY and Peerage.
All nice boys thought he was cool.
(However, he wondered why girls like him or what a harem is.)
Everyone's surprised by his innocence.
The girls promise to educate him on this topic.
All boys laugh at his innocence.
(Nevertheless, he promises to marry his big sister Rias, who gave him that promise.)
"That's right, sweetie. I love you too." said a smiling Rias.
(His other big sisters Team RWBY also want to marry him too.)
"We sure do, honey." said a smiling Ruby, earning nods from her teammates.
(He used to be Y/N Gremory but now is Y/N Rose.)
"Why?" asked the worried girls.
"What happened?" asked the also worried boys.
"You'll see." said a sad Rias.
(In the Gremory family, his father, mother, and older brother hated him for his innocent nature and saw him as an embarrassment to the family but his older sister Rias was in love with him and protected him. She would always watch in tears as her so-called family beat Y/N up just for being an innocent kid. She would step in to defend him but got slapped by their father for her troubles. Their mother didn't care and claimed that it was a scratch, they'll live. She hated them for how they treated her brother but she would still be the one who hugged her brother and assure him that he's special. He loved his older sister and fell in love with her, which she kindly returned. Then one day, their horrible brother claims that if Y/N wanted to be noticed or be powerful then he would have to pray for it in the next life and take a swine dive off the roof of the their home, which broke Y/N's heart and angered Rias but their parents found it funny.)
Everyone gasped at this and were sad.
"That's horrible." said a crying Hermione.
"Poor baby." said an also crying Annabeth.
"I fucking hate them!" said an angry Tayuya, much to everyone's agreement.
(However, Rias saved him by giving him an escape route but made him promise to be very careful, which he agreed to and they shared a goodbye hug as he escaped and went to go find his new home.)
Rias smiled at remembering that.
Ruby and Yang hugged her as a thank you.
(When he was walking, he was attacked by a Grimm but was saved by Summer Rose and he told her everything. Feeling bad for the kids and feeling responsible for saving him, she adopted him and took him home.)
