Arc 1The Assassin’s Gambit
Jizi served as Assassin in the Fourth Holy Grail War, balancing her mission with her bond with Rin as she clashed with the other Masters and Servants. After drawing Berserker into the battle against Caster, she disrupted the kings’ gathering with Eva-01, leaving Tokiomi and the others beneath its falling shadow.
- Jizi accepted a deal to enter the Type-Moon World as a female enforcer in exchange for healing her blind sister’s eye, then Kirei Kotomine summoned her as Assassin.
- Jizi grew close to Rin Tohsaka, who left Fuyuki for safety, while the Masters summoned their Servants and Jizi pledged herself to Gilgamesh.
- Kirei ordered Jizi to assassinate Tokiomi, but she infiltrated the Tohsaka Residence instead and was killed by Gilgamesh before rebuilding her puppet body.
- Jizi tracked Caster, disguised herself as Joan of Arc, and lured Gilles de Rais toward Einzbern Castle, where Saber and Rider fought his Sea Demons.
- At Einzbern Castle, Kiritsugu fought Kayneth while Kirei captured Irisviel, and Rider and Saber drove Caster into the forest before Saber’s attack was interrupted by Kiritsugu’s Command Seal.
- Jizi stopped Irisviel’s Mana attack from striking Kirei, then went to help Rin investigate Caster’s murders, where she fought Sea Demons and summoned Berserker to protect them.
- Jizi warned Kariya Matou that Zouken Matou could not be trusted, then escorted Rin home after Berserker stopped attacking her.
- Jizi’s music brought the kings together, but she summoned Eva-01 and sent it against Rider’s army, ending with its shadow falling over Tokiomi and the other spectators.
