Saraku

Saraku (査楽) is a minor character in Toaru Majutsu no Index. He is an esper and an operative of MEMBER.

Battle Royale Arc
While Accelerator was on his way to District 23, and after learning how Hikoboshi II's orbital laser works from GROUP's informant, he receives news from "Unabara" that the hacking of Hikoboshi II is BLOCK's doing, with the plans of eliminating GROUP. Upon arriving, however, he is attacked by Saraku who is there trying to delay Accelerator who unlike him and the rest of GROUP knew of BLOCK's true goal. Thinking that he had the upper hand because he could get near Accelerator's choker and had already bent the sight on his gun, Saraku was unprepared when Accelerator shoot him self to redirect the bullet at him with even higher accuracy then if he had used the sight. Though it appeared that Saraku was apparently killed however the Professor later disclosed that MEMBER should recover him since he's still alive.

Ability
His ability is Kill Point (死角移動 (キルポイント) ). He can teleport behind a person, but since he cannot calculate the theoretical value of the 11th dimension, he needs to know that person's current location in order to activate his ability.

His ability wasn't originally called Kill Point, but it's a name that Accelerator calls it since Saraku couldn't teleport through calculations involving the 11th dimension, and the Professor seemed fond of the name.

Power Level
It is unknown if his Level is actually 4; Accelerator noted that an esper who's able to teleport their own body is already considered a Level 4, but with the impairment of not being able to calculate the 11th dimension, a failure like Saraku couldn't be good enough to be a Level 4.
