Ki's Body is a location in Final Fantasy Legend II.
The party collect the MAGI located through Ki's body while fending off the shrunken minions of Ashura. One can be found in each of her hands, her feet, her heart, her stomach, and the last is in her brain. In order to access the last area, the player will need to collect all the other six MAGI before being able to enter her brain.
Once the party has acquired all of Ki's MAGI, they enter her brain and find the last MAGI being guarded by one of Ki's cells. Once the Phagocyt are defeated, the party exit her body and became full-sized again.
