Koharu gets frustrated by Hiyori trying to help her so much as she's fishing and Koi celebrates her sixteenth birthday.
Oh, but I've only ever done fly fishing...

Ah, aber wir nutzen nur Fliegen …
Oh, pero solo he pescado con mosca.
Mais uniquement à la mouche…
Però peschiamo solo a mosca, per cui...
Mas eu só sei pescar com fly...
