Kamisato Kakeru

Kamisato Kakeru (上里翔流) is a character introduced in Shinyaku Toaru Majutsu no Index. Similar to Kamijou Touma, he holds a mysterious power in his right hand, the World Rejector, a power that is the exact opposite of what the Imagine Breaker represents. With this and his similar background, he can be viewed as a counterpart to Touma.

His appearance in the story marks the abrupt end to the magic god subplot that began since the end of the Othinus debacle after defeating most of the remaining magic gods in the world.

Appearance
Both he and the narration describes him as a normal high school boy. He has brown hair and eyes, and wears a uniform consisting of a white formal shirt with a blue tie, a blue jacket buttoned by two gold buttons and grey trousers.

Background
Not much is known about Kakeru other than the fact that his existence is unknown even to Aleister Crowley. At the time of his first appearance, only Laura Stuart knew he existed.

Magic God Invasion Arc
While Kihara Noukan was busy killing the High Priest, Kakeru was out and about and using his World Rejector in "exiling" the magic gods. His first appearance in the story is him easily exiling Niang-Niang, much to Nephthys's shock, right after they decided to destroy Academy City in order to kill the one (Noukan) who can kill them.

After defeating Niang-Niang, Kakeru explains that he has defeated all the other magic gods apart from the High Priest and Othinus as well as the nature of his power to Nephthys. Nephthys tries to stop herself from falling into the temptation of the World Rejector, mustering enough willpower to try and create a new phase where Kakeru is defeated as she had the ability to hold her powers in reserve. However, it is too late; Kakeru crushes the phase she tried to embed in the world, and she is then consumed by the World Rejector.

Despite this victory however, Nephthys manages to escape thanks to her being a mummy, with organs separated from her body, allowing her to escape after leaving her primary organs to be consumed, much to his dismay.

Abilities
Kakeru's ability is the World Rejector (理想送り (ワールドリジェクター)), a mysterious power that resides in his right hand.

When it was used by Kakeru it allowed him to "exile" the magic gods into the unused portions of the world. Each of the magic god will have their own portion of this unused part of the world depending on their "ideal" type of world. Because of this, Kakeru describes their "exile" as their "salvation". Unlike the Imagine Breaker, Kakeru doesn't needs to touch his target in order for it to work as merely opening and closing his hands can affect the magic god with his power. When used, the effects are slow but apparent as demonstrated by the "exile" of Niang-Niang. She was not wholly sent to her ideal world immediately, thus allowing Nephthys to see Niang-Niang's ecstasy at being sent to her ideal world. Nephthys upon initially seeing Niang-Niang's "exile" first assumed that Kakeru was absorbing her. As an extension of this, not only does the World Rejector "exile" magic gods, but it can also crush their powers even when they are at full power, as demonstrated by Kakeru after he easily crushes her attempts in changing the phase of the world again.

A side-effect of seeing the World Rejector in action is that the magic god would be tempted greatly to simply be exiled by World Rejector. Indeed, Nephthys quickly tried to use her reserved powers as a magic god before she fell into the temptation of the World Rejector.

Difference with Imagine Breaker
World Rejector is the exact opposite of what the Imagine Breaker represents. The Imagine Breaker represents the ideal for magicians and magic-users that will allow them to fix, repair, and remain in the current world, while World Rejector is the complete opposite. World Rejector on the other hand gives them an illusion that will let them abandon, leave, and throw out the current world. Nephthys describes World Rejector as the "hope" of magicians.

According to Laura Stuart, World Rejector solidified because the incomplete Imagine Breaker could not contain the dreams and desires of all magicians. Because of this, these desires and dreams overflowed to create the World Rejector, their hope that would grant them these dreams. So if Imagine Breaker represents the hope for magicians to return the world back to normal, then World Rejector represents the hope for magicians to escape the world.

Quotes

 * (From NT13): "I am the kind of normal high school boy you can find anywhere."

Trivia

 * The name "Kamisato Kakeru" is actually a play on words that hints at his actions against Gremlin. "Kamisato" (上里; lit. "upper village") can also be written as 神里, meaning "gods' village" or "divine village", and "Kakeru" (翔流; lit. "soaring current") is homophonous to the verb 欠ける, meaning "to be damaged/broken". Thus, as a whole, the name "Kamisato Kakeru" can be written as 神里欠ける, creating a phrase meaning "[the] gods' village is broken". This fits how, through his ability, Kakeru has eliminated multiple magic gods affiliated with Gremlin.
