Hey guys, I have another theory about Darker Gale and his possible host. In my previous comment I said the Gramps was probably a misdirection, someone presented in the story as a suspect to draw attention from the real culprit.

Gramps is shown having the Mark of Courage, meaning if he wanted to he could use the Ginga Spark, but we don't know if that also applies to the Darkness Spark, I doubt a pure hearted, old and contented Priest would have the darkness in his heart to be suitable for such an object.

My attention turned to the person told about the Dark Lords presence in the school, the Principal. Gray (Alien Nackle) seems like the playful type and the principal seems more likely to be the host. Her school was shut down, we have no idea what she is doing with her life right now, in fact she seems to like have a reason to come to the school as if she misses it. She may possibly be dealing with depression after all her life's main purpose, the school, has been shut down. Also in the trailer she is seen fainting in the Shrine room, where the spark dolls are kept, possibly their appearance may be causing memories to return painfully.

But it's just a theory, we'll have to wait until the episode comes out.
