Is Gate Keepers coming back?

Set in an alternative 1969 Japan, a special group of teenagers has been gathered together under a secret government operation known as Aegis, to fight an enemy trying to take over the earth... called simply, "Invader". The Invader can turn ordinary citizens into zombies under their control, and only the Aegis agents, called the Gate Keepers, have the special ability to open the "Gate" separating the Invader's dimension and our own, and be able to eradicate them. The show opens with ordinary high school student Ukiya Shun witnessing an Invader attack, and quickly realizing that he is one of those with special power, is indoctrinated into Aegis. Each agent has a different ability and method of attack, everything from magic arrows to hallucinogenic piano music! Also crucial to story is young Ruriko, an experienced member of Aegis who has to work hard to prove her worth after the obviously powerful Shun joins the team.
