I hope I am not too late for this challenge ^^''
Element: Music
IMHO, Music is an element that could be found in any anime and manga. We've come to love their theme songs and for myself, there is never a time where I could say I'm bored listening to their songs and singing along ^^'' I believe that without music, anime would be just moving pictures and without anime and manga, we'd never enjoy music as much as we would expect.
I featured Mio from K-on! as music is the best element suited for her IMHO. K-on! songs are very cheerful and their rhythms are very catchy Killua-san, sorry for this late wallie ^^'' but hope you like it as much as I did.
Hope you all like it though there are better wallies for this challenge ^^ Credits below~!
