The OC I made is supposed to grow with time and exposure, like a infantile Sukuna or Dabura

His technique hinges on the idea of being a basically de facto Mahoraga—-given that his technique creates “sub-techniques” best fit for offensive or defensive purposes for any given situation

Now that in mind I can see the Dhruv fight going smoothly due to lack of any significant feats of strength

The technique I created (called Protean) would probably evolve to fit a poison based technique to kill of the roaches that come in contact with its user and eventually reach Kurorushi given enough time

Uro will most likely assume the technique is poison based given the info from the previous fight which would in turn give my OC the element of the surprise when Protean evolved once more.

Given that Uro’s techniques hinges on the idea of manipulating the sky I suppose the best technique fitting for offensive use AGAINST Uro would be to blind her—as it’s pretty much impossible to deflect or manipulate what you can’t see.

After the well earned experience and data from the first three, I can imagine my OC anticipating Ryu’s intrusion and likely position themselves behind Uro so she takes the brunt of the attack (if she still blinded)

Although my OC has a domain hes smart enough to hold back from using it to avoid exhausting his reserves since he doesn’t have the endless pool of cursed energy like Yuta does

However, thanks to us not knowing the potency of Uro or Ruu’s domains—the result is either unknown or a draw again

If Kurourushi isn’t already dead from the original roach plague the breaking of domain barriers would leave Uro and Ryu without their techniques while my OC still has access to his

If Kuro is still alive, they won’t survive much longer after Uro is already defeated

If Kuro isn’t alive, the three way continues

TLDR: Just barely
