I see

It seems like Oganehei's secret technique prioritizes targeting the red-eyed, shiny guy holding the kanabō that initiates attacks, if there are any attacking demons. If not, it targets randomly. I was imagining a flashy skill, but sometimes there are isolated attacking demons, which is personally helpful. I kind of wish the flashy skill would go to the rare version. With no duplicates and a special small-range 4-piece clear, the number of pieces cleared is modest, but Oganehei just makes me feel energetic by looking at them, so I have them in my party. They have firepower too.
