Amami Vs Hirata, deception, mind manipulation and faking a loss by the good guy and reveals a trap to take down Hirata who was controlling three very powerful shikigami.
Harutora facing Shaver and nonchalantly setting him on fire after deciding to protect Natsume. He then uses the same spell Kagami used on the Nue, completely eliminating the deranged servant.
