Despite the circumstances, Tsukiko holds no grudge against Senya and is determined to become Shinsuke's disciple no matter what.

While the unlikely trio heads towards their next destination, Tama Youko continues her journey to find the trail of Jinka, the nine-tailed fox who has the power to destroy the world.
