In a world destroyed by the emergence of a portal to Another Space (AnoS), which spews out monsters from other worlds, humanity is nearly extinct. To fight this threat, humans created an armor called Relic. In the past, there was a legendary hero known as Rellic N502, who managed to clear 2 AnoS in one day and eradicate 30,000 B+ and A+ level, as well as disaster level, monsters. However, he was killed by Professor Dr. Hades Silk and was held in prison, although he is still alive today. N502's armor, which has extraordinary power and energy but cannot yet be used by anyone, is stored and the case is closed.
The focus of the story shifts to Akaya Sinanhomiya, a child who enters Meka Academy. There, he learned how to control and fight monsters using the Relic. Despite initially having average abilities (76% strength and 7.7% energy), Akaya was unexpectedly able to synchronize herself with Relic N502. This unlocks great potential in battles against monsters and reveals the mystery behind the Relic N502's incredible power.
