It's Ren's first summer vacation in Japan. The landlord of the apartment he and Haru once lived in hires him to clean one of his apartment units. Haru becomes unbearably curious when Ren refuses to tell him why he got a part time job. Kiyoka suspects Kiri, Ren's female classmate who has been coming over with her dog to hang out, but...? And while this is happening, an unknown man suddenly approaches Ren--?!
Since it's the Day of the Ox, 
I'll get you some eel.
Heute ist es so heiß wie in der Savanne,
da isst man Aal.
Como es el día del buey,
te compraré anguila.
Como es el día del buey,
te compraré anguila.
C’est la journée du bœuf, 
mangeons de l’anguille.
Visto che oggi è il Giorno del Bue,
ho pensato di offrirti un po' di anguilla.
Já que é Dia do Boi, comprarei 
 uma enguia para você.
