When anyone found themselves in a new place and unfamiliar situation, they needed to find a starting point for themselves.
In Adam's case, it was the Raven Beak and meeting Helasa and Reyla. But that wasn't enough. He needed to become part of the city, to find his place here, even if he wasn't going to stay in Izardo for too long.
Fight clubs were a great solution. This way, Adam could not only earn money but also attract the attention of the Hybrids, which was practically his goal for coming to this city.
Sure, in theory, Adam could have done it himself, without Helasa's help, but that would have been problematic. The idea might not have occurred to him, and what's more, he didn't know where the fight clubs were located or which one would be best to go to.
Helasa not only had connections in the city but also knew every important place in Izardo very well. It was her duty as a long-time resident of this city.
Step. Step. Step.
