Murakamo must be destroyed

Hachiro attacks joujin, and hadaebou takes the opportunity to continue his mission. Joujin easily defeats hachiro, but then surprisingly sheathes his sword. The group of ninja regroup and shaizou tries to analyse kujaku's inverted halberd of time technique by firing test cannon balls at the murakumo. Hadaebou gains entry to the murakumo but realizes that tadanaga no intention of returning and has fully allied himself with joijin. Meanwhile joijin tries to convince hachiro to join him, but hachiro refuses and then escapes when hibiki and shikibu create a diversion. Joijin calls kujaku to fire his shiroku cannons at the ninjas which causes a massive earth displacement. Hachiro grabs hibiki, and as their eyes meet, they again create a powerful maelstrom of light, the ouka. They create the ouka again to defeat joujin, but rinne magoroku arrives to transport joujin back to the murakumo while hachiro and hibiki collapse into unconsciousness. Shaizou finally realizes that kujaku's technique has a time limit and during that period, namemba flies over the murakumo on a kite and successfully fires a cannonball into the tower, causing a series of explosions which consume the murakumo in flames.
