Arima vs Azuma

I meant combat speed, mb. Azuma's amps let him blitz other ftl characters like Vlad, so his increases would be the same, they would not fall under still being slower.
"Speed Amplification techniques are assumed to grant the same percentile of increase to a character's equalized speeds, as they would to their usual speeds."

Arima has a faster reaction speed, so he can counter Azuma's blitz amp. His reaction speed, heightened senses, and skill also made him counter Kaneki's AD and kakuja amp, so Azuma simply won't be able to blitz him.

No. You can just have a special source for your regen. If you think special source equals unconventional then think of it that way by all means. Still it doesn't address the source of the regeneration being from the super cells.

An unconventional type of regeneration definitely outweighs the limited negation of regeneration. Thus, regeneration won't work on the Ajin from the manga of the same name, even if it's crap like Yoriichi's cell evaporation. Because Ajin regeneration is based on special particles beyond human comprehension, infinite in volume and disintegrating any matter in their path.
If Choujin has something similar, then I agree that the quinque won't be as effective. If not, then at worst, the quinque will slow down regeneration.
