I honestly didn't even notice that, but it's also a strap-on that shoots out semen and stays perfectly attached with no signs of being a strap-on outside of one single panel. The wiki doesn't make any clarifications about how such a thing should be tagged, and I've often seen such situations tagged as futa before, rather than strap-on.

So, This is a somekind of strap-on which is 100% looks and feel the same with penis (just like some stuff I found on Neptunia doujins) that are able to eject some semen-like stuff?

Kancolle futa doujins gave me new lesson everyday.
