Viz has announced World Trigger volumes 1 & 2:

The fan-favorite WORLD TRIGGER debuts in graphic novel format from VIZ Media on October 7th, with a simultaneous release of vols. 1 & 2 on the same day! Fans may purchase the first two print volumes of this scifi action series at favorite retailers everywhere, and also digitally through the VIZ Manga platform and the storefronts for Kindle, iBooks, Nook, GooglePlay and Comixology!

The popular manga is currently serialized in the digital anthology WEEKLY SHONEN JUMP *simultaneous* to Japan, and follows our hero Osamu. As a member of the elite agents of Border, he fights against invincible monsters from another dimension called Neighbors using co-opted alien technology. Osamu may not be the best agent, but he’ll do whatever it takes to defend life on Earth… When he meets a feisty humanoid Neighbor named Yuma though, everything he thinks is right is turned on its head!
