Ami is being her usual goofy self when Ouka suddenly yells at her. It turns out "Ouka" was actually Ouka's twin sister, Kikka, and she proceeds to insult Familia and all six of its workers. It seems Ouka and Kikka have a complicated relationship...
Your sister showed up at the beach hut 
in some weird disguise today.
ظهرَتْ أختكِ في كوخ الشّاطئ
بزيّ تنكُّري غريب اليوم
Sua irmã apareceu na cabana
usando um disfarce esquisito hoje.
Твоя сестра сегодня заходила
в пляжный домик в странной маскировке.
