Profile

An artificial being that was created to stop Justice's revival. With half of the soul of Sol's past lover, Aria, she has a split personality: one is that of a collected adult, and the other is that of a child-like one. Therefore, in order to control her mood swings, she wears a mask when in battle.

Jack-O' carries the title "A mischievous fighter who fights together with Servants". Jack-O' is voiced by 五十嵐裕美 in Japanese and 이가라시 히로미 in Korean. Jack-O' was released on 24 March 2022.

Jack-O''s introduction: Your psyche is... Ehehe... Okay, yeah, let's just start.
