Akko either leave or join in.... Wait I like my second option better. I would love to see a threesome between Akko and her sensei's. Plus, I love it this pair!! XD.
I love how you didn't just draw the two lovers ;33 making love, but yet also spaced it out and created a very visible surrounding as well around the lovers ;33
I thought she looked somewhat like Kao from New Game! But that might be because I've never watched Idol Master and am just associating Miki with someone I do know.
