Waver Velvet is a magician from the Fate series, initially a dissatisfied student with average skills who enters the Fourth Holy Grail War by stealing a catalyst meant for his teacher Kayneth, summoning Rider Iskandar. Starting as an insecure Master seeking recognition, he undergoes profound growth through his bond with Iskandar, learning responsibility, self-acceptance, and leadership. Surviving the war as the only Master, he feels guilty for Kayneth's death and takes over the El-Melloi classroom, becoming Lord El-Melloi II. Now a renowned instructor at the Clock Tower despite mediocre magical talent, he is acknowledged for his teaching charisma and efforts to restore the classroom's glory.
