He enslave of the humanity seeing them weakest race. Until then.... He was defeated and seal by the Heroes who lead united of other races against Giff using the Ancient Vistamps against him known as Alliance United Force...

Kaito: 30 years ago, my father was one of the researcher to researching about the ancient demonic races and magic of origins. They had breakthrough of demons needed in order to regain of their physical bodies to separating from humans. So he created the Vistamps with Mystic Codes to boost up of the Magic Circuits.

Okita: A human forms the cult worshipping the demons... That kinda scary to us.... 

Musashi: No way... We fighting with Masters and Servants and now... We fighting against of Demons.

I created of the magecrafts, demons, genetic DNA of memories of powerful orgasms. So the system can allow us to capable harnessing the powers of demons... Is Kamen rider Revice! 

Musashi: Kamen rider... Revice?

Nero: I see... When Master Shirou transformed summons of his armor his other partner appear! They have team name of Revice but split of different one is Revi that Master and Vice is the demon.

Kaito: Exactly! And also... Kamen rider system will allowed them to battle and combat of the Servants that I've been prepare. *Smirk*

Musashi: And you make it prepare for Holy Grail War?

Kaito: Did I prepare for Holy Grail War... Of course I do.... I designed the Revice System placing mystic code since I research about Servants. So Revice and Rider systems has capable to battle not only combat against Deadman.... But also Servants. Seeking to end the battle of War... Remember I use Kiritsgu as experiment researching of the Servants in Previous War? *Sit down on chair*
