|This article is about a/an Phantom in Kamen Rider Wizard.|
Caitsìth (ケット・シー Ketto Shī) is a Phantom who was born from a African man who gave into his despair. Though a strong fighter whose claws are strong enough to fend off attacks from swords, and he can transform his arms into golden swords, Caitsìth is actually very lazy in personality, as seen when he fled from his first battle with Wizard because it was too troublesome to continue fighting.
His Gate target is the pianist Eisaku Takagi (高木 栄作 Takagi Eisaku), who has been practicing piano since childhood, attended a music college, but has fallen into a performance slump.
In his second battle against Wizard, he was almost killed if Haruto hadn't run out of magical energy. Once Haruto regained enough, he challenged Caitsìth once again. Caitsìth then summoned Ghouls to attack Wizard, only for them to be easily defeated when Wizard used his Copy Ring to defeat the Ghouls, by gunning them down with a hail of bullets as each one of them used the WizarSwordGun.
Though Caitsìth tried to flee, Wizard changed to his Hurricane Style and easily caught up to him. Caitsìth once again summoned more Ghouls who were once again, easily defeated. Caitsìth then met his end when Wizard used the Hurricane Slash Strike to defeat him, without despairing Eisaku.
