And now we wait another 4 months.

So it's a fairly typical harem comedy except that the main character has a vagina

Just call it yuri harem comedy. Your crude comparison pretty much reduces yuri to 'het, except no one has a penis'.

My point there was that in this specific case it might as well be het, as the MC fill all the functions of typical harem protagonist and even looks pretty androgynous

That's not true (yet atleast). Almost every harem MC is simply nice and has no other personality. You can't judge a character based on one chapter atleast give it 3.

.... It's seNpai

You saw me standing alone without dream in my heart, without a love of my own.

I'd rather live with this pacing than with any of shounen jump's series. A single battle takes a lot chapters, good grief. Anyway, does anyone know how old is Yuri and the captain?

According to their profiles, Yuri is 15...no, 16 by last chapter - and Marina is 20.

Thanks! Captain, she's still a minor! (but oh well)

She's only a minor in a few places. In Japan, most of Europe and a lot of states she would be legal.
