The song remains me a bit of Miku's Merry-Go-Round (also done by mothy). But still, it's a good song to hear and as always, the story is also worth to know. Gobanme no Piero takes place in Rolled City, Lucifenia and takes time on E.C.610 or one year after Nemurase Hime kara no Okurimono. Gobanme no Piero actually tells about Pere Noel, an organization that was "behind the scene" in Nemurase Hime kara no Okurimono. The story is told from Pierrot of Number V (Kagamine Len). He said that his main job was to punish naughty children. There were 5 members of Pere Noel: V. Pierrot (Kagamine Len), I. Santa (seems to be Meiko), III. Nemurase Hime (Princess who Brought Sleep, Margarita [Miku]), II. the blue one (maybe Kaito?), and VI. Samurai (unknown, perhaps Gakupo). Apparently, Pierrot admired Santa so much. One day, Magician of Number VII (unknown, seems to be Luka?) asked Pierrot to runaway with her. Pierrot refused and he told Santa that there was a traitor in her house. The next day, The Magician was missing. In the end, when Pierrot was doing his job, he was shot by Sniper of No VIII (also unknown, probably Gumi? Remember in Saigo no Revolver, Gumi said that her revolver was from "Santa"). Then in his dream Pierrot saw his real parents smiling at him and The Magician was laughing at him because he didn't escape with her.
Now we know why Elluka in Nemurase Hime kara no Okurimono said that she and Gumillia needed to know more about Pere Noel. It's because Margarita was actually one of Pere Noel member. And I also assume that Julia (Margarita's friend who told her about the "medicine") is Santa (that's why I'm pretty sure Meiko takes role as Santa). By the way, I guessed the Vocaloid roles in this song by the color given by the translator, animeyay (from Anime Lyrics).

E.C.610 Rolled-city Lucifenia
At 2 a.m., in a town shrouded in night's darkness, who will be the victim?
I will need to punish the bad children, since that is my job as Pierrot.
Ms. Santa has taught me that the world is infested with mistakes.
I, Pierrot of No.V, will dance once again in today's dark night.
The silly-looking boy, with his face painted white,
thrusts his silver knife into a chunky pig.
Tonight the restless Pierrot, in a circus devoid of an audience,
plays his flute to the moon, and then dyes the blackness into crimson.
Today, too, the magical cage enclosing the ecstatically dancing Pierrot has been opened,
and that wild beast, while jumping through fire hoops, wanders in the street.
~Members of "Pere Noel"~
V. Pierrot → the yellow one (male)
I. Santa → the adult woman sexy beauty
III. Princess Sandman → the first green → retired ✝
II. the blue one → he will never get his debut
VI. samurai → used for chores and others
The Magician of No.VII, with her gentle yet gloomy eyes,
tried to ask me to escape from this place with her,
so I told Ms. Santa that we had a traitor in the house.
The immediate next day, the Magician became missing.
Gently caressing Pierrot's head,
Ms. Santa's hand was almost...
There was another job for Pierrot today. I waited for my prey in the dark back valley.
Suddenly, I heard a rupture sound, and everything changed from black to crimson.
Pierrot's chest hurts! Pierrot doesn't want to die! I don't want to die!
Standing soundlessly before my eyes is the Sniper of No.VIII.
Tonight the restless Pierrot was very tired, so he closed his eyes.
In his dream, he saw his real father and mother smiling at him.
Pierrot will not be able to dance again. "See, I told you to escape with me!"
Muttering and then laughing wickedly was the Magician of No.VII...
