I'm Strongggg! Cure Sky VS Kabaton

Synopsis

Driven into a corner by his string of failures, Kabaton challenges Sora to a one-on-one duel. Hearing that, if Sora wins, he will lay off Ellee for good, Sora accepts. Heading to a campsite with everyone, Sora trains with the "Master of the Mountain" that Tsubasa has tracked down. Three days later, when Sora reaches the riverbed where the duel will take place, Kabaton hurls himself at her, using Undergu Energy on his own body. But Sky makes use of what she gained from her training to drive him back. Breaking his promise, Kabaton tries to snatch Ellee away, but Sky, together with Prism and Wing, keeps her safe. Defeated, Kabaton is attacked by storm clouds the Undergu Empire sends down on him, only to be rescued by Sky. Moved by Sky's action, Kabaton resolves to make a fresh start in Sorashido City. Meanwhile, with some lingering unease about the Undergu Empire, Sora and the others look up at the blue sky and renew their promise to protect Ellee together.
