Homonoia is a dōjutsu that casts a powerful genjutsu on the target to controll his mind. The technique allows the user to enter the mind of any individual within their field of view, and manipulate them by giving them false experiences, making it seem as if they were doing things of their own free will. It is regarded as a genjutsu of the highest calibre, due to the victim being entirely unaware that they are being manipulated. Shizuki is able to apply this dōjutsu on multiple targets. Unlike most Yasugan-based genjutsu, Homonoia doesn't seem to require eye contact.
