Author notes/ wish

I should begin that my mc is cold and manipulative and yet charming and friendly willing to do anything if it furthers his goal. Kinda like Lelouch from Code Geass

The Power of Absolute Obedience", allows him to plant commands within a person's mind upon eye contact in a manner comparable to hypnosis. Activation of his Geass is visually represented by the manifestation of a Geass Sigil in his left eye. Commands dictated in this state are written into the minds of the designated targets once the Sigil projects from his eye to theirs. Lelouch could initially toggle Geass activation at will, but subsequently lost this control

Lelouch's Geass, bestowed upon him by C.C., gives him "The Power of Absolute Obedience", allowing him to plant commands within a person's mind upon eye contact in a manner comparable to hypnosis. Activation of his Geass is visually represented by the manifestation of a Geass Sigil in his left eye. Commands dictated in this state are written into the minds of the designated targets once the Sigil projects from his eye to theirs. Lelouch could initially toggle Geass activation at will, but subsequently lost this control

Of all the Geass abilities in the series, Lelouch's has been explored the most, and also seems to have the most restrictions and side effects of any Geass introduced:

Only affects the nervous system.

Commands must be issued verbally.

The victim must make direct eye contact for commands to be issued. The maximum effective distance is 272 meters. Line of sight via a reflective surface is sufficient for the effect to occur.

Commands may be issued only once to any given individual, but any number of commands may be issued at initial application so long as eye contact is unbroken. Since Jeremiah's Geass Canceller negates all Geass effects, those exposed to it may be commanded once again.

The victim will not perform any action disallowed by their physical or mental capabilities, though they will try to carry out the command to the best of their ability. For example, a victim will not be able to correctly answer a question they don't know the answer to, but will direct the user to someone who can if they are able. However, commands that affect the mind or consciousness (such as erasing memories or seeing hallucinations) are possible despite the fact that the victim could not normally force themselves to do so. Also, commands that ask for something unpreventable and physically impossible, such as telling a dying person to "not die", will have not make them immune to death. It should be noted that in non-canon appearances, his Geass could be used to unlock memories (Another Century's Episode: R), or put someone into an eternal sleep (Lost Colors).

An action will be carried out for as long as dictated in its command, or upon the indicated conditional circumstance. Eye contact does not need to be maintained for command execution to occur. No upper limit has been established, but the conditional command Lelouch gives Suzaku is still in effect more than a year later.

The victim's memories for the duration of command issue and execution are sealed and cannot be recalled.

As demonstrated in Princess Euphemia's response to the command that she kill the Japanese, a victim may resist a commanded action to some degree if it is utterly repugnant and morally incomprehensible to them.
