I stopped going by my real first name when I was 8, I can't remember why I chose my new name.

My middle name is Hyène... means Hyena in French. I didn't used to have a middle name, but I legally added it when I was old enough, it was always my nickname in highschool, and my favourite animal.

And my last name was my half-brother's middle name: when I started living with him I didn't want to keep my old last name, but I didn't want his last name, so I took his middle name.
