The Second Rune-God Windam, the Lord of the Skies - S1.E15

Innova asks Zagato to have his turn to try and kill the girls, and he agrees.

In Cephiro's very first storm, the girls take refuge in a cave, near the sky shrine, where another Machine is being held.

When Fuu starts to worry about Ferrio, she brings out her communicator, only to be called by him. He tells them, he's nearby, and want to take refuge with them. Just before entering the cave, Ferrio notices a girl lying on the ground, holding a herb. Fuu is excited when she sees Ferrio's silhouette, but is crushed when he sees him carrying a girl.

The girl then wake up, and introduces herself as Selah. She starts to explain she leaves on the bottom of the mountain, and needed the herb she had to cure her brother's fever.

They then all take rest, but Fuu can't sleep. When she is about to talk to Ferrio, Selah beats her to it. Ferrio offers her some soup, she not only says yes, but offers to put the herb in it. She then gives it to Ferrio to taste.
