Ayano is trying to conduct an aura analysis of the remains, if that is still possible.
Then - roughly estimate what these "patterns" and "figures" on the ground represent and what they might have been made for.
Then - detect any unholy power/evil emanating from them or from the surrounding space, including the thickets.
Then - see if there are any bloody or other traces leading away from the remains, and if so, where they lead.
After a close examination of the patterns and figures on the ground, it could be concluded that they had absolutely no meaning and were made by someone who had no knowledge of the relevant sciences. They looked more like the work of a madman than some cultist or wizard.
Based on the aura of the area, it could be assumed that someone had cut up the victims, done their deed, and then calmed down - apart from the grotesque remains, everything around was calm.
There are no traces.
