How to find a monster. There were many ways to find a monster, Mariah could have hunted them down using her ability to see heat signatures, she could have hunted them through her chakra sight or she could do none of that and instead resort to something a lot more brash and loud... Which was exactly what she done, little else was to be expected from Mariah. She took a deep breath, or a facsimile of one due to her not needing to breathe, and let out a loud roar over the surrounding areas. It would definitely be enough to scare away all the smaller monsters but hopefully it would attract the attention of a humanoid beast.
Once she finished her roar, she rolled her shoulders and crossed her arms over her chest, hovering just above the ground and waiting for her opponents to show. This probably wasn't going to be too much fun, she had to kill monsters after all but it would probably be easy, she wasn't a weak genin, in fact such an idea was laughable!
