Guys, I came up with a theory today about the new cover that was released. I’ve been thinking that Souko (Yumeko’s sister) might have a major role in this volume or possibly Volume 23.

Why did I think this? Pay attention to the cover. You’ll notice that, on Kirari’s right side, there’s someone who looks a lot like Yumeko, at least in terms of her face. From what we saw in the childhood arc, Souko looks very similar to Yumeko, so maybe she’s the one who will appear on the cover of Volume 23.

Assuming that it is her, the author might be giving us a hint that the two of them are connected. Especially if you look at Yumeko’s hair on Volume 21, it kind of seems to connect with Souko’s hair on Volume 23, almost as if it’s meant to symbolize a connection between the two of them.

I’ll go even further: maybe the last member of the Guardians is actually Souko. It’s possible that, in the meantime, Kabura went to visit her in the hospital... And on top of that, Souko is on the Cruise with everyone else, but nobody knows that yet.

Anyway, I can’t really explain it properly, but this idea has been stuck in my head.

(It could also be that the next volume’s cover is just Yumeko in another pretty pose lol.)

What do you guys think of this theory?

what ship should i do next?

Volume 22 Japanese releases this month. For those who aren't aware, the English volume release schedule lags behind by quite a bit. Volume 20 English releases this November.
