:

As the girls train in summoning animal spirits, Asuka is the only one having trouble summoning hers. Her grandfather, the legendary shinobi Hanzou, comes to visit and informs her that their family's spirit is the tree frog, which Asuka is afraid of. As Asuka attempts to get used to frogs, Hanzou informs Kiriya that the evil Serpent Girl's Academy is behind the puppet attack. On their way home, Asuka and Ikaruga are attacked by one of the enemy shinobi.
