Official Mekami

The year is 2078, an unstoppable force known as the Krytanis invaded Earth to seek a mysterious artifact. The humans were no match against Krytanis superior weaponry and were forced to hide in secret. This all changed when a group of scientists from Earth discovered a way to use the Krytanis weapons against them. Seeing this as humanity's last hope, the humans gathered the remaining supplies and assembled a resistance force called MEKAMI to battle the Krytanis army.
