Laid off six months ago and calling internet cafes his home ever since, Ishida Shinta's life has damn near hit rock bottom. Luckily (?), a curious posting on a shady job site may just be his saving grace:
Looking for someone young and fit.
Will pay 100 million yen once done.
Just kick up a fuss; easy peasy.
Probably done in a day.
A payout of 100 million yen? Now that's an offer no one can refuse.
On the day of the job, Ishida arrives at a hospital to meet...a man in a strange mask? He almost thinks twice, but dons the outfit with his new friend as he and "Niconico Man" march into the hospital on Christmas Eve, with everyone in "Celeb ward" on their naughty list.
As of December 24th, 2011, 2200 hours, you of "Celeb ward" are all under the rule of I, Niconico Man!!
