S1·E24 Engetsurin

After seeing Raiko's body, Raimei and Gau try to attack Hattori, but are easily defeated. Hattori then blames everything on Miharu, who begins to believe it is actually his fault. Acting on his desires, the Shinra Banshou begins to awaken, much to Hattori's and Ichiki's glee. As Tobari uses the Engetsurin, the past is revealed regarding how Miharu possessed the Shinra Banshou. Hattori explains that he wants to possess the Shinra Banshou. Tobari attacks him, but is easily defeated. Yoite, on the other hand, drove himself to kill Hattori.
