Julian Casimir is a member of the Counter-Joker Agency, born and raised in the Kingdom of Ira. Julain holds the rank of Rank 2 Investigator in the CJA.
Julian is a very kind, well meaning young man with nothing but the best intentions for the world. Having been taught his entire life that Jokers were horrible and inhuman, Julian joined the CJA, wanting to better the world by ridding it of what he believes are terrible monsters.
- Holy Grail - Holy Grail is the robe that Julian wears, made with an unimaginable amount of magic circuits woven through it. This robe is able to act as a false "Holy Grail", and temporarily call Heroic Spirits down from the Throne of Heroes to possess Julian's body for a short amount of time, making him a Demi-Servant. Some servants are too powerful for Julian's body to endure at this point in time.
