Pretending to be a member of the Shinsengumi, Kurata Tenzen arranges a meeting with the chamberlain of Osaka Castle in order to acquire the "Assassination List" which lists the names of those who oppose shogun rule. But as a consequence of Choshichi's tip-off, the chamberlain quickly realizes that their guest is in fact Kurama Tengu. Kurata is then seriously injured as he attempts to flee from the castle retainers. He manages to take refuge in a storehouse on the castle grounds, but finds himself under siege as retainers surround the structure. When Kondo Isami hears of this, he heads to Osaka Castle on his own in order to settle the score with Kurama Tengu man-to-man.
