Giff

is the main antagonist of Kamen Rider Revice. He is the extraterrestrial progenitor of demons who arrived on Earth in ancient times. After becoming dormant, he remained hidden for centuries until his excavation in 1971, leading to his revival by his worshippers, the Deadmans. He attempted to submit humanity to his servitude using his contract holder Hideo Akaishi, but ultimately opted to destroy it upon meeting resistance which led to his demise by the Igarashi siblings. 
==History==
===Background===
Giff is an extraterrestrial being that feeds on the malicious energy radiating from organisms. He had destroyed many alien civilizations across the universe, one of which was the homeworld of Izangi and Balidelo. Amazed by mankind's ability to give birth to malicious energy en masse, several millennia ago, Giff arrived on Earth and wished to co-exist with them. However as time passed, the many civilizations that rose and fell, all viewed Giff as a malevolent devil. One of them was an ancient prosperous civilization in America that was annihilated overnight for opposing him, leaving only their leaders, Hideo Akaishi and Azuma, behind. Before Giff could do the same with the rest of mankind, both convinced him to let them be the mediator between both races. Giff formed a contract with the two men, granting them immortality before entering a long slumber. Although Giff was still in his dormant state by 1971, he had determined that humanity had evolved to the point that their evil would cause them to destroy themselves. In order to protect his food supply, he arranged it so that he would be found by a team of South American archeologists, preparing for his own awakening.
===Studied by the Government===
Being deemed an by scientists, organizations such as NOAH desired to weaponize him and created the Vistamps. After Masumi Karizaki created the powerful yet lethal Vail Driver, its prime candidate Junpei Shiranami received a DNA transplant from Giff to bypass the lethality, however his future children: Ikki, Daiji, and Sakura Igarashi would also unknowingly receive Giff's DNA as well, essentially making them Giff's descendants.
===The Deadmans Crisis===
Following the fall of NOAH, Giff's coffined state was stolen by Akaishi who worshipped it as the leader of the Deadmans. The cult also sought out Giff's relative Diablo to help progress Giff's revival, but he was destroyed following his own standalone plans to take over the world for himself, though this still had a positive reaction to Giff which was a sign that his revival was imminent. 
Though Orteca told Aguilera that Giff's revival requires six sacrifices, it actually only needed one which was her. During the process to fully revive Giff, the Deadmans Base was destroyed by Ikki Igarashi, thus halting the process but not restarting it due to both Amahiko Haitani and Yasushi Kudo having been absorbed. Giff's coffin is then seized by Fenix who continue to research it under the direction of George Karizaki and Akemi Mikoshiba.
===Approaching Revival===
With Giff's stamp in the possession of Orteca, the Gifftarians are then unleashed into the public, with each defeat fueling Giff's revival due to the creation of each requiring one human sacrifice. With his revival imminent, the warning signs are seen with the negative effects having spilled over Vice, Lovekov, and Kagero. Eventually, Giff's coffin became sentient enough to consume humans on its own. After his influence over Vice is temporarily halted with the creation of Jack Revice, the continued energy absorptions make the latter go out of control on its fellow Riders. In the midst of Jack Revice's rampage, Orteca fuses with Giff to acheive Phase 4 in the hopes of surpassing the devil himself, but is defeated by the new Kamen Rider Revice. 
With his revival having been completed, Orteca is then absorbed while Giff sheds his coffin remains off revealing his true form. From then, he lies in his own personal domain with his victims floating around in cocoons. He had communicated with Akaishi to destroy the Fenix Skybase and several parts of the city while fighting the Riders. Ultimately after Akaishi falls, Giff's attempt to form a new contract with Daiji instead fails as he pulls Vice into his personal domain. He revealed his intent to destroy all of humanity except for his own family, the Igarashi family, who shared his DNA to Vice. However thanks to Daiji having regained Kagero and his balance of righteousness, EvilytyLive and Ultimate Revice are able to seal Giff back into his own domain temporarily.
===Final Battle and Destruction===
However, Giff would eventually find a way to escape from his domain by using Vice as his host. He would then offer the Igarashi family a chance to become his herald for the new world before leaving. After some time, Giff appears again with his army, confronted by Ikki, Vice and Daiji. 
Vice would enter Giff's domain, while Ikki and Daiji fight the demon lord. Within the domain, Vice discovers Giff's coffin and managed to destroy it along with Ikki, removing the demon's immortality. Greatly weakened, Giff immediately sics the copies of Deadmen on Igarashi siblings, but it is all for naught as he is destroyed by their combined Rider Kicks. Just before he met his end, Giff reminds the Igarashi siblings that humans will always repeat their mistakes over and over again.
===Legacy===
Following Giff's destruction, it created a rift that persisted for over a year. George Karizaki would obtain his eyeballs and keep it with him. However, Chic would then steal one of them from George and use it to power up the Chimera Driver.
The last remains of Giff's power dwelt within Koshiro, the newborn of the Igarashi family. Izangi and Balidelo, a duo of aliens who came from another planet that had been ravaged by Giff himself and Colus, a former Game Master for the Desire Grand Prix, schemed to use Koshiro's demon to conquer the universe and create an eternal Desire Royale, respectively, although their plans were ultimately thwarted by the efforts of Kamen Rider Revice and Kamen Rider Geats.
==Personality==
Although much is not known about Giff's personality, he is shown to be ruthless and unsympathetic towards his enemies. This lack of sympathy even extends towards most of the Deadmans, as he devoured Orteca and slapped Aguilera out of rejection. The only exception is Hideo Akaishi, his loyal contract holder and servant, showing that he expects complete obedience, as Orteca allied with him to take his power, and Aguilera chose to become a Deadman when she was meant to be his vessel. For some reasons, Giff prefers avoiding direct combat unless necessary, usually having his underlings to do the work for him while he retreats to his own realm.
