Gate Keepers 21

📖 SYNOPSIS

"Gate Keepers 21" is set thirty-two years after the initial defeat of the Invaders. The once-powerful organization A.E.G.I.S. has been dismantled, leaving only a few Gate Keepers to protect humanity. Ayane Isuzu, one of these remaining Gate Keepers, is disillusioned with society and fights the Invaders primarily out of resentment towards her father. The story takes a dramatic turn when Machine General and Devil Count, two formidable Invader leaders, are revived. However, they are now accompanied by a mysterious ghost girl, adding a new layer of complexity to the threat. Ayane and the few remaining members of A.E.G.I.S. must overcome their personal struggles and unite to confront these resurrected enemies and the enigmatic new presence, fighting to save humanity from a renewed invasion. The series explores themes of duty, legacy, and the burden of responsibility in a world that has largely forgotten its protectors.
