Another thing to support the possibility though, is that I don't see why anyone would go through all the trouble of making this, just to get one of the names blatantly wrong. It doesn't add up. The fact that it's so unhidden actually works for it in terms of reliability (somehow!) for me.
With that it mind, maybe fake 90%/real 10% now?
The girl's name seems to be Airisu, Airyu (doubt it) or airiko. The last letter is too blurry for me to make out, but on this scan it comes out looking remarkably like the "su" in "Nyaasu", hence I lean toward it being "Airisu". (that and the other names just don't sound as right to me). Anyway, if it is "Airisu", then an appropriate English interpretation is probably "Iris' (pronounced like the part of an eye)
Also, the flying bat thing's name seems to begin with "Koro" and ends in "ri" (can't make out the 3rd letter!), this sound like a genuine naming sense for that kind of pokemon. (Koro being round and rolly). If it IS fake, then probably a Japanese person, or something with good Japanese knowledge made it.§
btw, take my readings of the names (except Ivy) with a pinch of salt. It's INCREDIBLY blurry!
