I like to think of myself as pretty relaxed about correcting translations or transliterations when new information presents itself. We've been saying "Precia", but the car she's named after was the "Presea"? Fine. The bridge bunny guys aren't Alex and Randy, but Allex and Landy? Sure, whatever. It's supposed to be "Raising Heart", not "Raging Heart"? Okay, I guess.
But there are times when a line must be drawn. I refuse to refer to the Best Dog in Multiple Worlds as anything other than Arf.
Back on topic, coming up with ear-licking from an entirely innocent place is amazing. More proof that Arf is best doggo, for facilitating this. May Madoka and/or Haruhi bless Nanashiki and bless NanoFate.
