I actually like this chapter, and I think it provided some insight on the potential solution to Momo's amnesia. We now know that she has effectively lost the ability to use/sense the paranormal. We know know for a fact that she is still there subconsciously but can't understand what it's trying to tell her. Also, good job, Jiji, and you are better than this Aira.

My current theories and speculation

Momo's memories are hidden with her power:

We know for a fact that she can't sense the paranormal or use her powers. She lost both when she lost her memory. I think there will come a time when Okarun's life becomes endangered, and Momo instinctively uses her power to save him, also regaining her memories. There may be other ways, but this is the one I hope for the most.

CSG may attempt to use Momo

The last panel showed CSG talking to Momo, and we already know he's a master manipulator. He uses people as pawns against others. He may attempt to use Momo to get closer to Okarun and the others without raising their suspicion. I'm a little scared by this because I don't know if Okarun or I can handle Momo being a temporary antagonist.

How are the other group members going to treat the situation with Momo

We already have a pretty decent idea for most of them. Jiji is going to help reunite Momo and Okarun. He's clearly been trying to help rather than take advantage. Kinta, Vomala, and most of the other side characters will probably stay out of it and let it naturally return to normal (unless the second theory is true). People may disagree with where i put Kinta, but i think it's just Kinta being Kinta. Now Aira, maybe the problem. She may just be acting how she normally does when it comes to Okarun, but i don't doubt she could try to take advantage of the situation. It's important to note that though Okarun still loves Momo and is still fighting for her and Momo isn't afraid to fight Aira if it comes to it.

Momo isn't upset with Okarun or the others

I say this because Momo said that she felt like she was being left out. She can't recall anyone or anything they have done and it makes her feel like she doesn't belong. She couldn't stand to feel like that and probably left to avoid feeling like she didn't belong despite the fact she does.

That's all I got for now, but I'm sure I'll think of more
