Isaac Ray Peram Westcott

Sir Isaac Ray Peram Westcott (in Japanese: アイザック・レイ・ペラム・ウェストコット, Aizakku Rei Peramu Uesutokotto), originally born as Ike (in Japanese: アイク, Aiku) and also simply known as Isaac Ray Peram Westcott, Isaac Westcott and later Second Spirit of Origin is one of the two main antagonists of the Date A Live franchise (alongside Mio Takamiya) and the catalyst individual to the franchise as a whole. He also served as the overarching antagonist in the games of Compile Heart studios and Date A Bullet spin-off, the overall main antagonist of the Chinese mobile game Spirit Pledge, the catalyst antagonist of the prequel spin-off manga Date A Strike and Nia Galge side-story and the overarching antagonist of the crossover game Danmachi Memoria Freese - Ais Catastrophe Campaign, becoming one of the main antagonists of Is It Wrong to Try to Pick Up Girls in a Dungeon? franchise under the form of Kaguya Ray Peram Westcott. He also appears in the Encore stories Ellen's Strongest Day and Mana Mission as a major character. Following his death in Volume 19, he becomes a posthumous antagonist in the final three volumes of the franchise's light novels, where his legacy and impact upon the world continued to haunt the heroes and humanity for centuries to come.

Regarded as one (if not the) of the most evil and the darkest Light Novel villain of all time, he was an abnormal and ruthless person yet a worldwide famous British brilliant man who worked as the founder and corrupt managing director of the largest company in the world, Deus.Ex.Machina Industries, a powerful military company that was responsible to arm all nations of the world to wage wars of aggression against the Spirits (all-female beings he created himself) and other political and military oppositions. Westcott was an intelligent, charismatic, composed and seductive man who ruled his company with a fascist iron fist and controlled almost all aspects of life inside of his company and had the entire Europe continent under his thumb. Recorded by history as the most powerful genuine magician who had ever lived, his entire life was the culmination of a half-century plan to destroy the current reality to create a new world by transforming himself into an Inverse Spirit and later in the Spirit of Origin to become a God-like figure. Westcott adopted the concept of supremacy as his aim was to unite "racially desirable" mages as comrades, while excluding those deemed either to be non-magicians and humans; including men, women, children, and infants. In his quest for genocide, he has been controlling the world's nations for 30 years, bringing waves of death and destruction across the globe with wars and terrorist attacks. His ultimate plan was not only make a world for Mages but to utterly annihilate humankind and create a new reality, a Nazi-like realm of Mages where he ruled as the supreme God for all eternity and planned to use every life form in the world as his playthings where he would torture, torment and kill everything and revive them to continue an infinite loop of eternal despair and sorrow, plunging the reality into diabolical torments to satisfy his own ego and twisted desire for pain.

Born as an innocent, altruist and kind magician, Ike was a genius of magic and was known by his village as a prodigy of his race who could probably have changed the world and the relationship between humans and magicians. After losing his pet and mother, Ike discovered he was abnormal and "sick" after he felt joy and happiness from the suffering of his family, friends and including his own. To keep his new hobby alive, he planned to get another pet just so he could watch it die and continue suffering. However, before it could happen, humans from the region discovered his village and wiped out the last remnants of his race before burning down his village, leaving only he, Elliot Woodman and the Mathers twins alive as the last magicians of the world after centuries of persecution. Adopted by the British Westcott family, a wealthy aristocrat family of United Kingdom, Ike, now known as Isaac Ray Peram Westcott, killed his foster parents in an "accident" to keep with inheritance of his new family and spent his entire youth with his friends, creating magical formulas and forbidden rituals. Growing up as an ambitious and cruel man who took the lives of millions, Westcott is the responsible for summoning the First Spirit (Mio Takamiya) and the person who created the Spirits to use their powers for his own gain, which resulted in the First Spacequake that took the lives of 150 million people and destroyed half of China and Eurasia 30 years prior the beginning of the series. Falling in love with Mio, Westcott captured her for himself to study her powers, from his research, his new DEM Industries company, created the Realizers and raised as the most powerful and important company of the world. After the First Spirit escaped from his laboratory, Westcott let his envy take over him after he discovered Mio was saved and was living with a Japanese boy called Shinji Takamiya, who took care of her and showed how beautiful the world was. Discovering their location, Westcott kidnapped Shinji Takamiya's 9 years old sister, Mana Takamiya and shot him in front of Mio Takamiya before she disappeared with his body. It was later revealed that Mio kissed Shinji's body turning him into a light to absorbed him inside of her for his childbirth to brought him back to life and allowing him to absorb and seal Spirits' powers within him by kissing them on the lips, starting the events of the overall plot. He is also the indirect creator of the Quasi-Spirits as well as the creator Neighboring World of Date A Bullet.
