Today is Celebri-Tea member Shirakabe Mako's birthday. Living with so many friends at Takako-so, Mako has good reason to expect a big party with lots of presents. However, for some reason, Mako isn't able to tell her new friends what day it is. Hoping to be pampered, but unable to say the word "birthday," Mako starts taking unusual steps to make her friends notice. Meanwhile, one other Takako-so resident also starts acting suspiciously.
Both of you forgot that 
today's the anniversary!
‫لقد نسيتما أن اليوم هو ذكرى مجموعتنا!
Aber ihr habt vergessen,
was für ein Tag heute ist!
ustedes se habían olvidado.
vosotras os habíais olvidado.
Vous avez complètement zappé !
Vi siete dimenticate entrambe che cadeva oggi!
As duas esqueceram
que hoje é o aniversário!
Вы обе забыли, что это сегодня.
