That's really sad....

I also think Mothy's going for her respective Vocaloid age(Hatsune Miku, Age:16) as a real-life reference, also as I recall from reading a book about "Samurais" in Middle School is that "13" is the legal citizen age in Japan(in contrast to America's legal citizen age being 18), but that's just me, though I think EC 600's Elphegort works differently due to being based off of real-life 1800's Germany.
