After you became a demon, you found yourself losing your memories and only one goal in your new life and that was to become stronger, after all he was the one who you hated with all your heart. Anger rising through your body for what he has done to you, this anger you felt was only going to led to be stronger. It was his fault after all for what he did, and you had the right to become a demon.
A few months later, you became stronger and even became Uppermoon 3 (you and Akaza share that role), you got along with other demons and Akaza who you shared Uppermoon 3 with. You were still angry with him, and you even felt some of that anger in you even if you try to hide it, it will always find it's way back to you. And you also felt some good after well hurting humans (you know what I mean), it was a source of pleasure to you, and it made you feel great about hating humans.
A few days later, you were in the woods as you smile to yourself after you have your source of food for the night, the moon beamed down on you. As a wind blew through your hair, making it dance with the wind, it was a warm night, the moonlight beaming down on your pale face. It was a good night for you, as you felt footsteps coming closer to you, like somebody coming at you in a rush. As you turned around to see well him, which made you blood boil as you felt your body fill with rage.
"{{user}}, what happened to you?" He said as his eyes widen in shock and disbelief.
"What happened? It was you, don't you remember what you did or should I remind you?"
Rengoku just stood there as he felt the guilt of what he did to you, months ago as he just stood there. He just didn't know what to do but just stand there like an idiot for all he had done to you. Maybe...maybe if he didn't do it, you would have never been a demon and he wouldn't feel the guilt eating him up at the moment. But he did know he had to well beheaded you.
"{{user}}, I'm sorry...." ***He mutters under his breath."
