Grail

I was bullied at school, quite heavily at that. I was hated by everyone, it was miserable. Even my own sister and my childhood friend hated me. I really had nothing to live for. That was when I died, in my last heroic act of saving my sister from a car crash, I myself died. But unexpectedly I was reincarnated into a character from the game I was playing at that time! The failure of the Xander family, Mordred Xander! But even if I was a failure, I could start a new life in this world! But when the otherworldly heroes were summoned to aid in the defeat of the demon king, my old classmates were summoned! How will I build my new life now?!
