Chapter 129 of "World Trigger" is already available for online reading courtesy of Bato. The chapter continues the battle between Galopoula agents featuring some very interesting development for fighters assigned in various locations.
Before any spoilers/predictions, here's a recap of the recently released chapter.
The battle continues with a team of attackers now assigned in strategic locations against Galopoula agents. Due to the overwhelming disadvantage in numbers, the group is now used for defensive purposes so they can stand ground together against various attacks.
They were reminded that a single casualty/loss could limit the firepower and capability of the team.
Out of nowhere, a trion soldier appeared that outclasses the troops due to its immense speed. The enemy was classified as an "ace type human shaped" trion soldier that could have a devastating effect if not controlled.
Kitora and Kuroe were sent to handle the enemy due to their speed and ability to fight in melee, close combat battles.
They were able to defeat the trion soldier with ease. It was later revealed that the trion soldiers are just vessels controlled by Yomi. His ability to control two trion soldiers at the same time is due to his "Perfect Parallel Processing" side effect.
He also figured out that if he could predict the movements of Kitora and Kuroe, he could eventually inflict some damage. The troops are ordered to stand their ground as the battle continues.
The next chapter will most likely continue the battle between Galopoula agents, Suwa group and the rest of the attackers. However, forum users for Manga Helpers predict some character highlights which would have some significant impact in the battle.
Yomi, Kitora, Kuroe and even Hisato would be featured in the next chapters. Forum users at My Anime List also discussed the capability of Yomi since he's the first neighbor to have a side effect which could become a game changer in the later chapters.
