Before I give my review for episode eighteen, I returned with seventeen to made remark about some general doubts.

Spoiler:

The Trinity obviously desires to retrieve Reiji Maigo for the purpose of immortality, specifically is for Hecate's sake.

Shuudonai's concern for Hecate hints that she has volunteered to be, I guess, the container to sustain the Reiji Maigo.

Exactly the Trinity's plans for Hecate don't differe much from Friagne's to had made Marianne into a living being.

What did Belpeol meant about Hecate calling for assistance from her (Hecate's) world within?

And why is it that Shuudonai is having misgivings about the Tomogara they hired, Dantalion, for their help?
1. Either The Professor works for the Tomogara Sovereign or
2. Has an agenda of his own.

I'm much to speculate that Dantalion will attempt to betray the Trinity somehow or other way in a near future.

As for Khamsin and Behemoth, they behave calm toward Kazumi explaining straightforwardly about the torches and guze, unlike other flames hazes behavior.
The scars on Khamsin's face quite indicate that he has endured several trauma against particular Tomogara in the past.

Exactly what is the job of Tuner Flame Haze like him?

Spoiler:

Khamsin explains that Tuners need help from a local human borned in the place where the
distortion erupted.

Kazumi happened to be chosen, because she maybe or not felt the ripple effects of the
distortion among the torches.

What does she needs to do for aiding Khamsin?

The Professor's plan.

Spoiler:

My theory he's cooking up some sort of time displacement fuzetsu to strain the Mistess holder of the Reiji Maigo, Yuuji, to exhaust all of his existence.

Once wasted the Mistess is deleted and the Reiji Maigo is freed for capture before moving onto another torch.

Belpeol mentioned that is what planned to use the Seirei-den. I wonder that Hecate, the Seirei-den, and the people to serve as sacrifice in the festival, all for energy to get the Reiji Maigo.

Anyways the plot is heading toward what is the Reigi Maigo, and unexpected surprises will be revealed along the way.

The new opening did not make an outstanding first impression, fortunately, I'm becoming so much very used to it listening over and over. Have to wait for the CD single to be released.
It's definite KOTOKO, but the song has not traditional flair of KOTOKO within the music
