Lovely Super Fantastic

About what is this drawing? 
Simple, is a crossover and seiyuu conection between two of 2 characters, whose voices are played by Hidaka Rina, my fave voice actress.  
They are Ayano Keiko, or Silica, from Sword Art Online, and Last Order from To Aru Majutsu No Index. Since I found out they shared the seiyuu, I was very excited and couldn't help making this crossover, I really hope you like it, it took me long to do Dx , don't forget to comment please!
