If you guys have listened to quite a lot of Vocaloid songs or Miku songs, then you might have come across this song-- "World is Mine".
That's what this relates to. I was listening to Gazelle's version of this song (yes, really really good Japanese fandubber who was on nico nico douga but quit... So now we can only listen on youtube... TTATT)
I drew this when I drew Miku and she seemed kinda Tsundereish so I thought of the "World is Mine" song and I used the lyrics and just drew this. Yeah, the Japanese is part of the lyrics.
The one by the pudding says "とろけるプリン". (lit: creamy pudding-- I'm not sure if it's exactly "creamy" but if you guys can think of a better word for it, that'd be great. ;3 That's why I can't be a translator.) That's one of my favorite parts of the song by the way. ;3
The one by the cake says "いちごののったショートケーキ" (lit: short cake with strawberry on top) (yes, I'm bad at kanji so I won't use a lot)
The cloud says the name of the song "World is Mine".
And the one under Miku herself says "わがままなんて言ってないんだから". (lit: I'm not saying any complaints)
