@RichardPercival: Evolution is just referring you Agito improving as a fighter. It’s not really referring to anything specific, it’s just thematically linked to Agito given the Gu ritual pretty much best in the concept of survival of the fittest into their heads. Formless just makes it easier for Agito and Lu Tian to “evolve” as they’ve developed a highly keen sense for combat that lets them analyze and come up with counter-measures on the spot.
@PyroclasticFlow: Following what N0b0dy07 said, this is less Purgatory vs Kengan Association as it is Worm vs Kengan Association. They failed to infiltrate the KA through Hayami, so this time they’re doing it through this merger deal after having already thoroughly infested Purgatory. So there really isn’t anything wrong with there having been these many infiltrators, and it’s already been hinted that the KA was aware of this and warned Toyoda in advance, hence why he’s called up Muteba now for a job.
Personally, I do find the fights lacking. Not really with the dramatic flow they have, but purely on the fight choreography itself. If I had to name what specifically, I’d say it’s the lack of more, uh, sequential action panels? Where you can clearly feel how each panel leads to another and the POV of the panel doesn’t feel too much like the scene is being shot from a different ion direction, or at least not unnaturally so. Okubo’s fight against Agito is a good example of what I’m talking about with his gimmick of transitioning between blows, throws, and holds.
Additionally, I feel like the authors are also starting to overuse that technique of having all these phantom limbs waving about in one panel, like when Lu and Agito were exchanging lots of blows all at once in a single panel. Makes it feel like they’re trying to condense the action in these fights instead of spreading it out more.
