For what I understand about Mantras, the mantras are needed to activate their abiliities. If i remember correrctly, their mantras are assigned during that whole hypnotic ritual with fire, so it could be possible that since they learn them during hypnosis, with a certain trigger like the paper dolls being burned, each person could be triggered to forget their own mantra. The monk managed to make each person forget their own mantras by triggering the earlier hypnotic suggestion. However, their abilities havent disappeared, they just cant use them. The mantra might allow them to focus enough to use their PK abilities. That is why they are so short and easy to remember, that way before using their abilities, they can recite their mantras quickly. There is a rule about not sharing mantras, and this is a culture where people dont break the rules. Since Saki learned Satoru's mantra outside of the hypnotic suggestion during that ritual, the monk would not have been able to make her forget his mantra, and could then teach Satoru his mantra again.

The one thing that seemed kind of interesting this episode is that I just dont trust the "ally" queerats. I might be too paranoid, but organizing so many ambushes for them without knowing where they are going to be would be difficult. It seems more believable that the allied queerats are directing the two kids through a path previously determined by the invasive queerats in order to kill/weaken them to a point where they are easy to kill. Idk, maybe the allied queerat queen was kidnapped or something like that, idk.

All of that is a ton of speculation though, its quite likely im wrong. I do really wonder what about what will happen next.

I wouldn't be surprised if we discovered that they gaining/losing their powers was just a form of hypnosis

fix his power but not hers. Until she breaks through the hypnosis, her power will remain sealed. I also wonder if she didn't get the "ceremony" completely right. It would help to explain his change of character, though the stress of the situation also helps with that.

I think there's some importance of the library getting killed before she could tell them the truth about the karmic demons. My guess is that it's some kind of descent into dark bloodlust. There were hints that the priest was going that way, and maybe the balloon dog was a creation of his own devising. There was definitely some kind of dark angel in the priests hurricane.

So unless Saki can snap him out of it, he may be headed along the same route.

Saki was right, they should of got out of there, the rats aren't her friends. The adults kept the children well away from the rats for a reason.

Looking forward to seeing Satoru lose control of himself. At least, that would be interesting to see.

From the preview we will get to here the fourteen year olds next episode with a two year time skip.
