Have fun with it ^^ if you want to have the full Single, then ask me (: I’ve got a lot of Higurashi music x3
When I requested it, I went with what I read on a Youtube comment where someone had uploaded a video with that song so I thought that it was HIMEKA XD But it works ^_^
Also, if you don’t mind putting it up, sure, I’d like the single too ^_^ But thanks once again!
