He is a member of the Sumeru Akademiya's Haravatat who is known as the "Scribe", and is loosely based on Su from Honkai Impact 3rd.
His localized name has a spelling mistake, where it should be written as either Al Haitham or Al-Haitham, with "Al" being translated as "The", which is comparable to writing La Signora as "Lasignora" or Statue of The Seven as "Statue of Theseven".
