The latest event in Fate/Grand Order, Fuun Karakuri Illya’s Castle, will add a new playable Servant, Kashin Koji. She is an SSR Assassin, and will remain available in the story gacha even after the event ends. Prizes for playing through Fuun Karakuri Illya’s Castle include the usual enhancement materials and QP.
Fuun Karakuri Illya’s Castle starts with Sitonai hijacking the combat simulator to create a castle full of traps. Chaldea’s Master and Servants must clear the floors in order to escape. The Kashin Koji banner also features Danzo and Kotaro, who will be major supporting characters of the story. Other characters in the event story include the Prisma Illya trio, Merlin, and Jiang Ziya,
As for Kashin Koji, he was historically an illusionist from the Muromachi period. Some sources state that he performed his acts for people like Nobunaga Oda, Mitsuhide Akechi, and Hideyoshi Toyotomi. However, there is no hard evidence for these feats. As a Servant in Fate/Grand Order, Kashin Koji is an AoE Quick attacker who is able to Bind enemies with her Noble Phantasm. Asami Seto provides the voice for her. Some of Seto’s other roles include Nobara in Jujutsu Kaisen and Kujou Sara in Genshin Impact.
Fate/Grand Order is readily available on mobile devices. The Fuun Karakuri Illya’s Castle event and Kashin Koji banner are only on the Japanese server of Fate/Grand Order.
