Koneko's senjutsu

The one who sent the Devils flying with her bare hands was Koneko-chan, who showed her cat ears and three tails! Koneko-chan’s Devil rank was Rook, and the Rook’s specialty was simple! It was the increase of offense and defense! Koneko-chan was originally a rare species even among the Youkai Nekomata, a [Nekoshou]. Having mastered Senjutsu, she was able to user her own Ki and the nature’s Ki, as well as controlling her Touki. Plus, she could also produce a Nekomata’s special power, Kasha. The wheel that Koneko-chan released — was covered with white flames that had the ability to purify as well. Devils would be burned to ashes if they got hit by that! Holy swords, light, purification, all of these attacks that we gave would give any Devil a fatal injury, so it wasn’t weird that those Devils flinched.
