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.
The next time you say "birthday," 
I'm gonna dump you in the Dotonbori Canal!
‫إن ذكرت ذلك مجددًا،
‫سألقيك في قناة "دوتونبوري"!
Di "cumpleaños" una vez más
y te hundo en Dotonbori.
Di "cumpleaños" una vez más
y te hundo en Dotonbori.
La prossima volta che parli di compleanno
ti getto nel canale Dotonbori!
A próxima vez que você disser "aniversário"
eu vou te jogar no Canal Dotonbori!
Ещё раз это скажешь,
скину тебя в канал Дотонбори!
