Keibi Keibi no Mi/Ojigisuru

Ojigisuru
Ojigisuru (お辞儀する, Literally meaning "To Bow") is a powerful technique created by Marshall D. Nicolas, using his great skill with hypnosis and his usage of The Mind Without Mind technique Nicolas found a new and effective way of using his devil fruit, while Nicolas' ability can only be activated when he is fully unaware that he is being attacked, after entering the stage of Mushin, Nicolas becomes only subconsciously aware of what's happening around him, meaning he would be only partially aware that he is being attacked, that is why in this state Nicolas keeps a part of his paralyzing ability, anyone who tries to attack him in this state will feel weightened down and half paralyzed, with their devil fruit abilities supressed making them uncapapble of controlling it properly, most opponents fall down on their knees when this is used on them and bow to Nicolas, thus earning it's name Ojigisuru (To Bow).

Using his incredible skill with Hypnosis, Nicolas would hypnotize his subconscious to preform Life Return after a short period of time from entering the state to reconfigure his Nervous system to the way it was before entering the state of Mushin, preforming the hypnosis is very hard to the point that Nicolas can't hypnotize his subconscious to do anything else but that. In that state Nicolas is still capapble of fighting while he is opponent is suffering from being weightened down and supressed, giving him a great advantage in battle.

This technique like any other technique has it's share of weaknesses, as Nicolas can't keep this state for too long and those with an exceptionally powerful haki and physical strength can resist and weaken the paralysis effect, but they won't be able to completely nullify it.
