Caster, ハンス・クリスチャン・アンデルセン

Caster is a Servant in the Moon Cell Holy Grail War of Fate/Extra CCC, serving Kiara Sessyoin. He also appears as a character in Fate/Grand Order's Grand Order conflicts. In terms of appearance, he resembles a young boy around 10 years old wearing formal clothing, but his voice is that of an older man and his body is covered in scales, burns, frostbite, and other physical traits. Despite being depicted as a Heroic Spirit during the "golden age" of their myths, Caster considers his childhood to be the time when he was most sensitive. He also gains sudden understanding, such as looking over materials from his past self and finding them embarrassing. It's possible that he was summoned at this age due to the interest of an evil woman in Fate/Extra CCC: Fox Tail.
