Self Marionette (セルフ・マリオネット) is a Movement Type magic that covers the users body in order to manually move the users physical body.
This Magic Sequence attempts to suppress the flesh’s magical resistance as much as possible while prudently taking heed not to surpass the extents of the joints movements; this can help create attacks that should be impossible according to human anatomy and physics. 
A weakness is that once a powerful blow is directly inflicted, this impression would rewrite the variables for the Magic Sequence. Using a Magic Sequence that did not have a complete command interface causes a theoretical miscalculation.
