I completely forgot to upload this. My bad. It was drawn by
This is an OC based on the NES game "The Guardian Legend" (originally Guardic Gaiden), developed by Compile in 1988. It is one of the few NES-era games to have a female protagonist, the Guardian of Earth (System D.P., nicknamed Miria in the Japanese version). My OC's name is Zhaina, as the title implies.
Incidentally, it's that Compile, the predecessor to Compile Heart. So I don't believe the similarities between the protagonist of this game and the protagonists of the Neptunia games are accidental. Especially with the whole "Guardian of Earth" title.
