PSI

PSI is the general term for various psychic abilities. It also is used to describe certain Magics which function the same way. It is notable for its use by Giegue, who uses it exclusively rather than mixing it with Magic like other PSI users. The term comes from the Mother series that Giegue hails from and was used to describe their psychic abilities. A particular sub-branch of PSI is PK or psychokinesis, which is most often used for attacks. ( Technically, PK could also mean Psychic Kappa, a name given for psychic abilities which effect the outside world which is distinct from Psychic Gamma, which is more what laymen would know as ESP. Related concepts include the difference between Kiai and Aiki. Coincidentally, PK Kiai is a thing, but has not been seen so far... )

Giegue's PSI
Giegue's PSI is unique. It operates in such an esoteric, cryptic way that it cannot be understood and sometimes cannot even be observed by others. As such, most of his PSI attacks themselves are described as "inexplicable" or describe by the similarity of their effects to known PSI. ( e.g. If Giegue uses a PSI which sets stuff on fire, it'll likely be called PK Fire or Fira.
