Hmm well then I make no excuses for the anime team but maybe Hiro was to busy drawing the other 3 omakes and the main chapter at the time and the editor was like "look Mira in a bikini and the old guys looking I approve." I kid somewhat.

Looks like he made a Nirvana mistake it happens, I looked at a couple of colored cover pages(390 & 400) and it should be more or less parallel to his belly button on his left side. Maybe the anime team read the chapter and saw he forget and didn't correct it I don't just throwing out random reason to see if one sticks.
