^Yeah, that's what he seemed to imply, I posted the page where he says that. Here's it again:

Spoiler for spoiler:

And now he has merged with a real angel and has become the ultimate being. In this chapter we have learnt that the process to copy a Stigmata is exactly the same of when you learn a fragment using the embedded crystal on the forehead, the only difference being the mark has to be activated in order to incorporate it in the system.

Arclight was already impossible, to the point his PF Zero had to be sealed in order for Blade to have a chance to hurt him even if it was just a little. But now? Now he isn't just impossible to defeat, he's invincible!! So terrifyingly strong he even told Riru to stay on the sidelines. Yeah, he's the very equivalent of a god now.
