Waver Velvet

Lord El-Melloi II, ウェイバー・ベルベット

Waver Velvet is an 19-year-old student at Clock Tower, which belongs to the Magus Association. He comes from a family of mages with a three-generation lineage. Despite his talent, he's not recognized by his peers or teachers. Waver proposed that a mage's power can be enhanced through hard work, experience, and knowledge rather than inheriting it from their magical ancestors. However, his idea was rejected by Kayneth Archibald El-Melloi, who dismissed it without further consideration after tearing up the manuscript.

Spoilers:

When Waver discovers that El-Melloi will participate in the fourth Holy Grail War in Japan, Waver steals the artifact El-Melloi intends to use to summon his Servant and runs off to Japan. Intending to win the Holy Grail in order to force the Magus Association to recognize his genius, he takes the stolen artifact and summons Rider-class Servant, Iskander.After the Grail War, Waver decides to continue living with the Mackenzies for a while in order to save up money to travel around the world. He also takes with him, among the many items accumulated by Iskander bought during their time together, the video games that the Servant bought but never had a chance to play. He eventually takes on the title of his former teacher at the insistence of Lord El-Mellois sister.
