Team Daenerys!
The swarming masses was something that Michonne was resolutely used to, she was exceptionally skilled at closer than close combat with walkers, enough that the closing in didn't deter her from swinging her blade with precision and power. At Wolverine's warning, she did exactly that, arms moving gracefully as she swung around and down to slice straight through the demons face.
This was where Michonne would admit that the more noisy but destructive power of the machine guns would be useful, both she and Wolverine had to let the beast get close enough to actually reach striking distance, and they tended to be limited to how many they could take out in a single blow. With the guns, it would be less trouble, but much noisier. They didn't need to attract further attention.
As much as Michonne was looking to go assist Wolverine as the monsters attacked in a higher number, she remained close to Daenerys, stepping to the side to impale one charging beast before pulling her blade out it's side to slash through another two. "Keep going." It would be easy to worry about their other companion, but the risk to aiding him was too great, although Michonne kept a wary eye on his progress just in case.
The focus was Daenerys, yes, but she wouldn't leave Wolverine to those beasts if she could help it either.
Razor sharp teeth came lunging towards Michonne and Daenerys, the dark skinned woman reacting on instinct to drive her sword up through it's skull, the beasts jaws sinking further down before she could yank it free. "You need to hurry, they're getting worse." This was indeed going to be a bloody, long and tiring night.
