Next Episode:

Margery had a dream about her past - that this Tomogara was burning and destroying everything Margery knew. She woke up with a fright. Sakai was training with Wilhelmina while Shana was watching. Wilhelmina summoned the first Rinne who attacked Sakai. Sakai was scared of it, and started to run, but later punched the Rinne and it dispersed. Shana praised him for him “overcoming” his fear. Wilhelmina was studying about the Keeper of the Mystes and found something. The next day she left in a hurry. Keisaku asked Margery to train him, but Margery told him about her past instead…

It was starting with the Tomoagara, Annaberg, looking at the world’s evolution… it’s industrialized growth.
Margery appeared and started attacking him. She thought she killed him, but some giant serpent dragon attacked her and left her too weak to attack back. The serpent was actually Sydonay, who was being paid to help the weighter dude. They left Margery alone and left. Margery got up and was refreshing herself using Marchosias. A boy appeared - I believe his name was Yuri. Yuri saw her naked. She smacked him and later he followed her. He seemed to have a mission similar to that of Margery. She spoke with her client about her job and Yuri, but had little information. Later on, she told Yuri to buzz off and Yuri started to talk about how he became a Flame Haze - his tragic life.Then she went to find the Annaberg.

This episode seems to be reviewing Margery’s past life. Yuri sure seems to be a messed up kid to have went off and looked at Margery. What’s this called? The opposite of loli that is.
Besides that, I truly believe that Sakai isn’t really getting any better at fighting. He just seems to be the same - fragile, weak, and dumb. He should seriously go out with Konoe. That’d be full-on loli.
