I just noticed you aske about aki, not aiki. Beats the hell out of me.
KAMI : Sometimes people just want to give a japanese sounding name to arts they "created". Bruce Tegner, of infamous memory in the 60's, "created" an art called JUKADO (you know it...JUdo, KArate and AIkido...); someone devised an art he called "X-Jutsu-Do" (Jutsu and Do together???) and in Brazil an art was "created" called "AMI-JUTSU"("Arte marcial Integrativa" Jutsu - Integrated Martial Art-Jutsu). I think I even heard about a "SUGAR-RYU JUJUTSU" (Heaven help us!)
The list is non-ending...
