Ushio Fukazawa is a friend's original character and is an idol for Shining Agency.
Allannah is a quiet girl that had a troubled past. She was taken away from her family at a very young age. Where Allannah was taken to was to Alice Academy. That's where she meets her closest friend, Ushio Fukazawa. Both friends have had tragedies happen somewhere in their life.
Ushio lost her parents at a young age and was sent to live with her grandparents before being sent to Alice Academy for some time.
Allannah was a bit too young when she was taken from her family, so she really doesn't have any idea of who her family actually is.
After a few years of being trapped in Alice Academy, Allannah found a way to escape from the school. She had dropped school id, which had a tracker on it so the school could find her wherever she ended up, near the front gate and ran as fast as she could away from the school.
The head of Raging Entertainment, Raging Otori, found her and took her in. Allannah was ever so grateful that he took her in, and got her away from Alice Academy.
Allannah spent the rest of her middle school years and her high school years going to a normal school alongside Raging's sons, Eiichi and Eiji. What Allannah didn't expect was to fall for Eiichi as hard as she did.
Once HEAVENS got started, Raging made her their manager. Whatever they wanted she had to get. Her work as their manager allowed her to be even closer to Eiichi. Neither would tell each other how they felt.
Ushio had lost her Alice shortly before entering high school, and had transferred over to Saotome Academy.
She met Syo when they both entered the S-class. They became pretty close while in the S-Class.
Syo and Ushio had trouble keeping the fact that they both liked each other from the group. They really couldn't do anything about their crush because of the no love rule that Shining had placed over the students attending.
Ushio and Nanami both get along really well. They've given each other tips about different things when everyone is together.
Allannah and Ushio finally saw each other after a few years apart due to Allannah running away from the Academy. They ran into each while out doing errands for themselves, or being rudely asked by a member of a band, and the friends were reunited at last. And this is where the story begins. When the two friends finally reunite.
