In Kengan Azura I had the impression that the formless was also a reflection of Agito's wild psycho side. Like you have both the physical skill and tech that also shows how vicious he can be. It was like "ey this guy is also in bad mood but when he gets some fun he reveals that psycho-mad side".
The perspective that now he's fusing the formless with his martial art skills kinda diminishes that "psycho-side" of his character. Like if it would satin somehow that perfect psycho he seemed to hide. I guess now that there was not such a psycho-side and it was just my impression. But I liked that pure wild side....
No doubt the formless depiction is really really cool, specially the eyes and the smile and the deformed positions of the body...
Anyway the chapter shows clearly that Sandrovish goes for the hype even going against the character design: Lu owns the formless as well as Agito. But Agito didn't perfectioned. Lu did, so he's above. But now: Agito fuses the imperfected formless with martial art. So Agito is above. Next, Lu owns kure tech, so he's likeli above, etc... You also can wonder how Lu owns the kure tech. But, anyway the fights keep being really nice to watch...
