GATE Anime-Planet

On August 20XX, a gate suddenly appears in Tokyo's Ginza district, unleashing a portal where monsters, medieval knights and other fantasy beings come from another world and wreak havoc on Tokyo. The Japanese Defense Force take action against these monsters and push them back into the "Gate". Third Reconnaissance Team is dispatched to the "Special Region" lead by officer (and otaku) Youji Itami. On their travels, they are joined by a beautiful elf girl who is a survivor from the dragon's rampage and guide the group across the dangerous new world.
