for anyone who doesn't know, the Hirokitachi are Takahashi Hiroki (Japan) and Yasumoto Hiroki (Germany). Two men with super sexy voices and exceedingly huge dorkage ratios.
sexy oniisan is Onosaka Masaya (France)
yes, I'm using Hetalia for my reference point today. lol. I don't know why. Well, I don't think Hiroki-san has joined the tenipuri dorkage yet. they are all in Bleach, however.
