P-Patchy! I find Kazunoko is not Kazu(Noun)'s children!! Kazunoko(herring roe) can be interpreted as "Kazu's children", if you think literally.

It is herring's roe, right? I knew it.

I've been fooled!! I won't eat them anymore!

How much did you have a special feeling for Kazu(Unknown fish)?

Nice to meet you, Ms. Remilia. I'm "Koakuma" who is a librarian of this library from today.

This shook me as much as when I knew Koa·Kuma was not bear. Koakuma...Koa-Kuma...Koa-Bear.

I don't think I want to employ a bear as a librarian.
