Based on the manga "Chieris Love is 8 Meters", a quite cute manga about a giant schoolgirl. It has been published in the US and I had it ordered at my LCS, unfortunatly that was when Diamond went tits up and I never got it.

Anyway, there was an AU omake in the books where the main girl Chieri and the other giant girl Neiro have kind of a growth contest which end with then in the terra range. But what if we would go further...?
