Koharu tries to convince her dad to let her go on a fishing and camping trip with just Koharu and Koi, which causes a disagreement in the family, and results in Koharu and Hiyori running away from home.
That's when I learned
that fish eat their own eggs...
...حينئذٍ عرفت بأن السمك يأكل بيوضه
So hab ich gelernt,
dass Fische Eier fressen.
Así aprendí que los peces
también comen huevos.
Voilà comment j’ai appris
que les poissons mangeaient leurs œufs.
Così,
E então, eu aprendi que
peixes comem as ovas...
