Haha, it's crazy to this point but to answer this:

Mika and Yu arguing about silly stuff is more like a touch of comedy; more likely to soften the dire situation they're on right now.

Second, I highly doubt Mitsuba will join and leave her squad behind in order to see her sister. Mitsuba more likely will meet up with the guys in order to get updated about he situation which more likely Kimizuki will tell that Shinoa is not acting herself or that she's lost; perhaps he'll have a mix of feelings.

And yes, definitely Yu will be exclaiming: I must save Shinoa, she's my family; meanwhile Mika will be like: no Yu, let's run away, we can't face up the first progenitor.

For Guren...I think Guren will make his last battle; to be honest, there's a theory I updated in a spanish fandom but, it's really long. It'll take a while to translate it to english haha; but I can see how his betrayal will go; he'll more likely won't obey Rigr on the meeting point since Shikama mentioend about Mahiru going to Shinjuku; which is something I can see as a betrayal, Guren and Mahiru won't go there; same with Krul, she's focusing on her brother but of course, the deal might have consisted on bringing her close to him from a certain method but well, the deal will break somehow due to the fact that Yu will be with Asuramaru a little longer.

Likewise, Shinya will be focusing on searching up for Guren, to the point he'll see Mahiru in charge again.

Man this will be a party for next chapter and yes, you're right on that. Urd and company will finally reach the first progenitor
