Tenzen among with Azuki Rousai, Nenki, Hotarubi, Jingorou and Koshirou 
decided to search for Kazamachi in order to kill him before he reaches Kouga manjidani and tell to the others that the war has begun. This would definitely give Iga the advantage. Tenzen also orders Jingorou to go back to the village and pretend to Gennosuke that everything is normal and even celebrate the arrival of Gennosuke at the Iga village. Jingorou wants to kill Gennosuke if he gets the chance but Tenzen disagrees because he believes that Gennosuke is too powerful for him.
After this short conversation the four remaining Iga (except Jingorou who went to the village) while they were searching for Kazamachi they get to find Jimushi Juubei (one of Kouga 
Manjideni 10) who was also searching for Kazamchi instead. They get shocked when they find out that Juubei has no arms or legs! Tenzen feeling confident for him self tells everybody to continue their search for Kazamachi and he will come find them after he finishes with Juubei. Juubei on the other hand is full of surprises. He manages to stub Tenzen with a knife that was hiding in his throat and knock him down.
The other 4 Iga finally get to find Kazamachi and attack him. Kazamachi quickly creates a spider web and immobilises all the Iga except Hotarubi who managed to dodge his attack. Hotarubi then attacks him with her secret ability that creates thousands of energy butterflies 
(cool soundtrack here) that attack him for enough time so that she throw one of Koshirou's sickly to Nenki who by his turn uses his hair to throw at Kazamachi and kill him. Just when Kazamachi was receiving Nenki's attack Juubei appears and Kazamachi throws him the scroll. Juubei for someone who has no legs or arms, he can travel very fast, faster than the other 4 Iga. But while he was trying to escape Tenzen appears in front of him back from the dead and slices him in two! Tenzen gets the scroll that was give to Kouga and burns it right away.
While Jingorou welcomes the unaware Kouga Gennosuke and Udono to Iga village the Iga seem to have the advantage for sure having 3 of Kouga ninja dead and being the only ones that know that the war has begun! What will happen with Gennosuke that is trapped in enemy territory? Will the Iga manage to finish the Kouga before even the Kouga find out that the war has begun? What will be the role of Oboro who deeply love Gennosuke?
