Perspective fail.
ANYWAY... yeah...
That was a fuckin cop-out.
Force-fed a potion, belly swells in seconds, a huge egg just fuckin pops out through her panties without any sort of blood and she goes right back to normal instantly.
... That is just so fucking stupid. Even if you overlook the instantaneous pregnancy (hentai has made me used to that sort of thing), that process should have utterly wrecked her body... and her underwear.
Oh yeah, and this blatantly isn't shounen. Looks like shoujo to me, despite the apparent bustiness of the girl relative to most usual shoujo protagonists. Given this is about birthing children it'd be a shame if she doesn't get to put those tiddies to use.
