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.
