Saku and Yukichi receive invitations to Yume's birthday party. Yukichi convinces Saku that it'll be completely fine to attend since it'll be a costume party. However, will Saku and Yukichi really be able to fool all the parents and children there?!
Thank you for always taking 
care of my little brother.
Ich hoffe, mein kleiner Bruder
ist Ihnen kein Ärgernis.
Seguro que tú también
ayudas mucho a mi hermano menor.
Encantada de conocer a una compañera
de mi hermano pequeño.
Ça ne doit pas être facile,
de supporter mon petit frère.
Ne sono felice! Sono certa
 che mio fratello minore conta molto su di lei!
Eu que agradeço por estar
cuidando do meu irmão mais novo.
Спасибо, что помогаешь
моему младшему брату.
