Oodles of Pop'n characters! [Pop'n Music]

Because the Pop'n Music franchise is celebrating its 18-year anniversary tomorrow, I decided to draw a whole bunch of my favorite Pop'n Music characters dressed casually♪ 

If you have been tagged here, it is because I need your help! I'm going to be digitizing and coloring in ONE of these characters (in the exact outfit and pose shown here), and your vote is going to decide who the winner is! If you're unfamiliar with these characters, I have included each character's name above the character for your convenience. Post the name(s) of the character(s) you're voting for in the comments. You can vote for up to 3 of them. The winner will be announced over the weekend! 
_{Pssst! If you know why I chose to draw Nico in the pose I drew him in, your vote will count TWICE! I know there are people who know exactly why in the list below...}
