Blurb
"Naruto and the gang return home after a stint protecting Shibuki, the leader of Takigakure. But there's danger back in Konoha. Sasuke and Sakura are quickly captured and the tow-headed ninja-wannabe finds himself in a desperate situation. Turning to Shibuki for help, Naruto discovers the revered leader is actually a coward and false hero. Alone, Naruto must protect his home, his friends and the Takigakure's Hero Water."

Trivia

 * Senji, an extra character who supports, helps and protects Shibuki and his villagers.


 * Three summoning animals being used in the light novel.


 * Senji fighting against Suien instead of Shibuki.


 * Suien's three Amegakure partners being revealed to be alive (and captured by Kakashi) at the end of the light novel adaption.


 * Team Suien having faced off against Kakashi until they had been interrupted by Suien's summoning animal, Konenmaru.
