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.
It's a death match. A life or 
death battle for presents.
‫إنها مباراة حتى الموت.
‫معركة مصيرية من أجل الهدايا.
Das ist ein Todeskampf!
Es un duelo a muerte por un regalo.
Es un duelo a muerte por un regalo.
Un combat à mort.
Notre vie pour des cadeaux.
Uno scontro mortale. 
Una battaglia all'ultimo sangue per i regali.
É um jogo mortal. Uma batalha
de vida ou morte pelos presentes.
Смертельный поединок.
Бой не на жизнь, а на подарки.
