Osamu Mikumo is one of the main protagonists of World Trigger and is a member of the Border with low Trion level. He joined the Border after Jin saved him. He is usually referred as simply "Four Eyes" by people outside the Mikumo unit. 

~!He is later promoted into B-Class Border and later became a Shooter and the leader of the Mikumo Unit.!~

One day, a gate to another world suddenly opens in Mikado City. Aliens invincible to Earth’s weapons, called “Neighbors”, start coming over. Earth’s only line of defense is a mysterious group called the “Border” who are armed with weapons called “Triggers”. 
 
Four years later, the city has recovered from initial attacks and citizens of Mikado City have started to get used to the Neighbor’s attacks. Yuma Kuga, a transfer student, and his classmate Osamu Mikumo find themselves fighting a Neighbor that suddenly appears. Osamu, who is actually a Border agent, activates his Trigger but is unable to defeat it. This leaves Yuma to activate his own Trigger and defeat the alien. Yuma reveals that he is not part of Border and is actually a Neighbor who has transferred from the other side.
