S1·E10 Revival of Selece, the Legendary Rune-God

The girls reach a lake, and Mokona reveals a Machine is in it. They travel underneath the water, to a place with air (thanks to Mokona.)

Umi doesn't feel good, and starts to glow. She wanders off, and suddenly they notice a painting of a blue dragon. It's start to come out, and Umi is cut off from Hikaru and Fuu behind two large doors.

Ascot then shows up with his monster, and battle the Hikaru and Fuu. They don't to much damage, but Fuu points out the glowing jewel on its head, and Hikaru breaks it. The monster becomes stun, and Ascot comes out.

He then goes on how they all killed his monster friends. Hikaru tells him if they were his true friends, he would not hurt them or harm them in anyway. The monster wakes up, and starts to go berzerk on them. Ascot runs away, while Hikaru and Fuu fights it off.

Meanwhile with Umi, the dragon tests her, by telling her to show her courage of the heart. She hear the screams of Hikaru and Fuu, and suddenly the doors disappear.
