Koharu gets frustrated by Hiyori trying to help her so much as she's fishing and Koi celebrates her sixteenth birthday.
If you leave those mats, you drown.
.إذا غادرتما الحصيرتان فستغرقان
Wenn ihr drüberfallt,
ertrinkt ihr und das war’s.
Si salen de ahí, se ahogan y pierden.
En sortir, ce serait se noyer.
Se uscite dal tatami, morite annegate, chiaro?
Se saírem daí, vão morrer afogadas.
