Either I’m reading too much into this due my inability to sleep rn or there is something with all this. As X in this series appears or gets emphasized on usually when it is related to hybrids in some manner.
@eto-when-and-where sorry it took me so long to get back to you. :3 Actually, leaving Hide’s headphones aside because a better version of the cover gave me the impression it rather seemed to be a ray of sunlight (not that it changes anything to these theories), I think the whole “X” thing really is supposed to imply hybrid/crossbreed:
Itori introduced the concept by making that X gesture with her fingers, but she also showed just one kakugan so far so… I’m not saying her being a OEG is the most likely possibility but, y’know, I wouldn’t exclude anything either until Sensei addresses the topic. xD Anyway, there seems to something personal about hybrid babies with her. EDIT: also…
you made a great point about Eto, who’s a natural OEG (it always was such a confusing part about vol 8 for me. I couldn’t understand why they’d refer to her as X)
same about ch125, even if it most likely wasn’t the day Touka became pregnant (unless ghoul pregnancy lasts longer than 9 months), but it was just to imply that Kaneki and Touka falling in love would eventually result in conceiving a lil hybrid baby
finally, there is a Uta: artificial or natural I don’t know, but there are hints that he could be a OEG. To give an example, the X headphones happened during the same chapter as….
