You thought your neighbors were bad...but at least they're not aliens trying to kill you! Earth is under constant threat from Neighbors, invincible monsters from another dimension that destroy our way of life. At least we have the elite warriors of Border, who co-opt alien technology to fight back! Meet agent Osamu Mikumo, not the best, but along with his Neighbor friend Yuma, he’ll do whatever it takes to defend life on Earth as we know it. Earth is under constant threat from Neighbors, invincible monsters from another dimension that destroy our way of life. At least we have the elite warriors of Border, who co-opt alien technology to fight back! Our hero Osamu Mikumo may not be the best agent, but he’ll do whatever it takes to defend life on Earth as we know it. When Osamu meets a feisty humanoid Neighbor named Yuma, everything that he thinks is right is turned on its head. Can the two natural enemies ever become friends? Gr 7 Up—A gate to another world has opened in Mikado City from which invaders from another dimension attacked, causing a defense group called Border to fight back. Osamu Mikumo, a Mikado City high schooler, is a member of the Border defense, but hides this secret identity from others. New transfer student Yuma Kuga is has even bigger secrets of his own. The two boys form an unlikely friendship that has far-reaching implications for the future. This is an exciting manga with a lot of physical and psychological action, including battles against gigantic monsters, tension between members of Border, and the constant threat of secrets being exposed. Civilians' minds are erased whenever they learn sensitive information, so every time they realize that Mikumo is a hero they are guaranteed to forget it soon afterward, which adds to the pathos that readers will feel for the hero. Ashihara's artwork is very dynamic, particularly in action sequences when the movement affects the size and shape of the panels. During these scenes, panels jut out and overlap at crazy angles, heightening the narrative's pace.
