Miss Kobayashi and the others go to the beach. But Lucoa's immediately dragged off by one of the lifeguards for her overly skimpy swimsuit. After regrouping, they put sunscreen on each other, split a watermelon, go swimming together, and enjoy summer to the fullest. After the beach, it's comiket! Tohru and Miss Kobayashi both head for the otaku's battlefield, and even Tohru gets shivers from the incredible aura surrounding those otaku. While helping Takiya with his circle, Tohru's horns and wings are mistaken as cosplay?!
Oh yeah, you humans can't 
breathe under water, can you?
تذكّرت، أنتم البشر لا تستطيعون
التنفُّس تحت الماء، صحيح؟
Sí, los humanos no pueden
respirar bajo el agua, ¿no?
Los humanos no pueden 
respirar bajo el agua, ¿no?
C’est vrai que les humains
ne peuvent pas respirer sous l’eau !
Oh, giusto.
Ah, é, humanos não conseguem
 respirar debaixo d'água, né?
А, точно, люди ведь не могут дышать под водой.
